Eight anodised colour options, a featherlight construction and a gearing range that spans track to road make this one of the most considered rear sprocket designs on the market.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighing just 350 g at the 45-tooth size — reduces unsprung and rotating mass for sharper throttle response\u003c\/li\u003e\n\u003cli\u003eEight finish options: silver, black, hard-anodised, orange, red, gold, green and blue — hard-anodised finish outlasts standard anodising under sustained load\u003c\/li\u003e\n\u003cli\u003eTwelve tooth counts from 37 to 48, all in 520 pitch, enabling precise gearing for circuits, mountain roads or fast motorway touring\u003c\/li\u003e\n\u003cli\u003eSprocket carrier bolt pattern 76\/100-5 hole — direct fitment to Marchesini, OZ and BST carriers with no modification required\u003c\/li\u003e\n\u003cli\u003ePrecision-machined profile for consistent chain engagement and minimised wear on both sprocket and chain\u003c\/li\u003e\n\u003cli\u003ePart number 201H for straightforward identification and reordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has long been a benchmark name among European racing paddocks, and the 201H embodies that heritage in a part engineered as much for the eye as for the drivetrain. The colour range goes well beyond the usual black-or-silver binary: the deep hard-anodised finish — a thicker, denser oxide layer than conventional anodising — not only looks exceptional but actively resists the abrasion and heat cycling that progressively dull lesser sprockets. Whether you choose the understated silver, a bold orange or a track-matched gold, every option is processed to the same exacting standard so the aesthetic does not come at the cost of longevity.\u003c\/p\u003e\u003cp\u003eThe machined tooth profile is clean and purposeful, reflecting the same design discipline that makes Sitta components a regular sight on Superbike-class machinery. Fitted to the lightweight forged wheels from Marchesini, OZ or BST, the 201H completes a drivetrain assembly that is genuinely worth looking at — not just performing well, but looking the part in the paddock or on the road.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the right tooth count transforms how a motorcycle feels and performs, and the 201H gives you twelve steps across a meaningful range. A smaller rear sprocket in the 37–42 tooth band lowers the overall ratio, extending top speed and easing engine revs on long, fast sections — ideal for circuits with extended straights or open-road touring. Moving up to the 43–48 tooth range raises the ratio, sharpening acceleration out of tight corners and improving agility through technical sections. With the 201H available across the full 37-to-48 range, there is a configuration to suit every rider and every circuit.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201H is designed specifically for motorcycles equipped with Marchesini, OZ or BST sprocket carriers using the 76\/100-5 hole bolt pattern. All variants are machined for 520 pitch chain only — confirm your carrier specification and chain pitch before ordering. This sprocket is suitable for both track and sporting road use.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: Sitta\u003c\/li\u003e\n\u003cli\u003ePart

RSV4 is as much about daily riding comfort as it is about outright performance. The Sitta 202P aluminium rear sprocket lets you dial in your gearing with twelve tooth options — from 37 to 48 teeth on a 520 pitch — so every ride, whether a weekend blast on the road or a full track day, feels exactly as it should from the first corner to the last.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight, high-grade aluminium construction strikes an ideal balance between durability and unsprung weight reduction.\u003c\/li\u003e\n\u003cli\u003eAvailable in 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47 or 48 teeth, giving genuine flexibility to tailor acceleration and top speed to your riding style.\u003c\/li\u003e\n\u003cli\u003e520 pitch compatibility across the full tooth range — ideal for standard and converted lightweight chain setups.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option delivers superior surface hardness and corrosion resistance for extended service life.\u003c\/li\u003e\n\u003cli\u003eFive-hole sprocket carrier pattern 100\/120-5 ensures a precise, rattle-free fit directly to the Aprilia hub.\u003c\/li\u003e\n\u003cli\u003eEight colour choices — silver, black, hard-anodised, red, gold, blue, orange and green — allow a clean visual match to any RSV4 livery.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAluminium Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta machines the 202P from high-grade aluminium alloy, keeping rotating mass low without sacrificing the structural integrity that a high-power V4 demands. The standard anodised surfaces resist everyday wear and corrosion well; the hard-anodised variant goes a step further, building a noticeably tougher surface layer that holds up on track where chain loads are highest and replacement intervals matter most. All colour options retain the core anodised treatment, so the finish is integral to the material rather than a superficial coating that chips or flakes.\u003c\/p\u003e\u003ch2\u003eChoosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eThe gearing choice you make here changes the character of the motorcycle in a very tangible way. Fitting a smaller sprocket in the 37-to-42 teeth range shortens the overall gearing ratio, raising top speed and reducing engine revs at motorway cruising speeds — a sensible choice for long-distance road riders or circuits with extended straights such as Hockenheim or Mugello. Moving up through 43 to 48 teeth lengthens the ratio, sharpening throttle response and intensifying acceleration out of slow corners — exactly what a tight, technical track like Oschersleben rewards. Because the Sitta 202P is available across this full range at 520 pitch, you can experiment and refine without sourcing a different carrier or chain standard.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 202P rear sprocket is designed to fit the following Aprilia models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 R (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2009-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eChain pitch: 520.

Aluminium Rear Sprocket for MV Agusta F3 675\/800 (2012-2026) – 37-47 Teeth, 520 Pitch (201A)","description":"\u003cp\u003eA rear sprocket that earns its keep day in and day out: the Sitta 201A is CNC-machined from quality aluminium and engineered specifically for the MV Agusta F3 675 and F3 800, covering all model years from 2012 through 2026. Whether your F3 splits its time between weekend road runs and occasional track days, the 201A delivers smooth, vibration-free power transfer and a weight saving that is immediately noticeable — all at a price that makes upgrading a straightforward decision.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUltralight aluminium construction — only 350 g at size 45 — reduces unsprung mass for sharper handling without compromising strength.\u003c\/li\u003e\n\u003cli\u003eCNC-machined for an exact, rattle-free fit on the 80\/104 mm, 6-bolt sprocket carrier standard to the F3 platform.\u003c\/li\u003e\n\u003cli\u003e520 pitch — the correct specification for both road-going and race-prepared MV Agusta F3 builds.\u003c\/li\u003e\n\u003cli\u003eWide tooth selection from 37 to 47 teeth allows precise gearing adjustment to suit your riding style and circuit layout.\u003c\/li\u003e\n\u003cli\u003eAvailable in hard-anodised, black, red, silver, gold, orange, green, and blue — so the drivetrain complements the rest of your build.\u003c\/li\u003e\n\u003cli\u003eResistance to wear under sustained high loads makes it equally suited to spirited road riding and regular track use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eChoosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eGearing has a direct and tangible effect on how the F3 feels beneath you, and the 201A range gives you genuine flexibility. A smaller sprocket in the 37-42 tooth range lowers the overall gearing ratio, raising top speed and reducing engine rpm at motorway pace — ideal if your F3 sees long open roads or fast, flowing circuits. Moving up to 43-47 teeth increases the overall ratio for stronger acceleration out of tight corners and a more responsive throttle in urban or technical riding. With eleven tooth options available, you can tailor the drivetrain precisely rather than settling for a compromise.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Everyday Reliability\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 201A from high-grade aluminium selected for the right balance between low weight and durability. The CNC machining process ensures every tooth profile is consistent, which means the chain seats and releases cleanly with each revolution — reducing wear on both the sprocket and the chain itself. The hard-anodised finish option adds a surface hardness that extends service life noticeably on sprockets that see frequent use. For riders who want a performance component that does not demand constant inspection or early replacement, the 201A is a sensible, long-term choice.\u003c\/p\u003e\u003cp\u003eNote: product images

Aluminium Rear Sprocket Kawasaki ZX-10R\/RR Ninja (2004-2026) 201W – 37-47 Teeth, 520 Pitch","description":"\u003cp\u003eEngineered for the ZX-10R and ZX-10RR across every generation from 2004 to 2026, the Sitta 201W aluminium rear sprocket lets you tailor your Kawasaki's gearing with precision — selecting from eleven tooth counts between 37 and 47 to match your riding style, whether that means chasing top speed on long straights or sharpening acceleration for technical circuits and spirited road riding.\u003c\/p\u003e\u003ch2\u003eKey

Count\u003c\/h2\u003e\u003cp\u003eGearing selection has a direct impact on how your ZX-10R behaves in every situation. Getting it right means the bike works with you rather than against you, and the 201W makes that adjustment simple.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket in the 37-to-42-tooth range raises overall gearing, reducing engine rpm at motorway speeds and extending top-end reach — the natural choice for circuits with long straights or fast cross-country touring. Moving up to the 43-to-47-tooth range shortens gearing, sharpening throttle response out of slow corners and producing more aggressive acceleration — ideal for tight, technical tracks or urban sportsbike riding where instant drive matters more than outright top speed.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta machines the 201W from high-grade aluminium, keeping weight to a minimum without compromising structural integrity under the sustained loads of hard acceleration and track use. The hard-anodised finish option delivers a surface hardness that outlasts conventional anodising, resisting wear and corrosion even when the drivetrain is running in demanding conditions. The seven further colour choices — black, silver, orange, blue, gold, red and green — allow the sprocket to complement or contrast any ZX-10R livery, from factory superbike colours to custom builds.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201W rear sprocket fits the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eKawasaki

rear sprocket is engineered to deliver exceptional power transfer and long-term durability on the Honda CBR 1000 RR across all three chassis generations — SC57, SC59 and SC77.

Each tooth profile is machined to precise tolerances, which translates directly into smoother chain engagement and reduced wear on both the sprocket and chain over extended service intervals.\u003c\/p\u003e\u003cp\u003eThe hard-anodised finish deserves particular mention: the electrochemical treatment creates a surface layer that is considerably harder than standard anodising, resisting abrasion from the chain side-plates and maintaining a cleaner appearance for longer. For riders who train regularly on track or cover significant mileage on road, the hard-anodised option represents a worthwhile upgrade in service life.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count reshapes the entire character of how the CBR 1000 RR delivers its performance. Opting for a smaller sprocket in the 37-to-42-tooth range reduces overall gearing ratio, lowering engine speed at a given road speed and extending the top-end reach — the preferred choice for fast circuits with long straight sections. Moving to a larger sprocket in the 43-to-48-tooth range tightens the gearing ratio, sharpening acceleration out of slow corners and increasing mechanical advantage — ideal for technical tracks or riders who want a more responsive throttle on the road.\u003c\/p\u003e\u003cp\u003eWith twelve distinct tooth options under a single part number, the Sitta 201N gives CBR 1000 RR owners a level of drivetrain customisation that is rarely available at this quality point.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is compatible exclusively with the 520 chain pitch.

Aluminium Rear Sprocket BMW S1000RR K46 (2009-2018) 202Y – 37-47 Teeth, 520 Pitch","description":"\u003cp\u003eForged from high-grade aluminium and finished in eight anodised colours, the Sitta 202Y rear sprocket is the definitive upgrade for BMW S1000RR, S1000XR and S1000R riders who refuse to compromise on either aesthetics or outright performance. Eleven tooth counts spanning 37 to 47 teeth let you dial in your gearing precisely, whether you are chasing lap times at a circuit or demanding everyday reliability on the road.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePremium aluminium construction keeps weight to just 350 g (size 45), reducing unsprung mass for sharper throttle response and more agile handling.\u003c\/li\u003e\n\u003cli\u003e520 pitch specification optimises the sprocket for performance and racing applications where every gram and every watt of drivetrain efficiency counts.\u003c\/li\u003e\n\u003cli\u003eEleven tooth options from 37 to 47 teeth give you granular control over your final-drive ratio to suit any track layout or riding style.\u003c\/li\u003e\n\u003cli\u003eAvailable in eight anodised finishes — silver, black, hard-anodised, red, blue, orange, gold and green — so the sprocket becomes a visual statement as well as a functional upgrade.\u003c\/li\u003e\n\u003cli\u003eHard-anodised option delivers a surface treatment measurably more durable than standard anodising, resisting wear and corrosion under sustained high-load use.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier pattern 110\/131 – 5-hole ensures precise, fuss-free fitment with no modification required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has built its reputation over decades by supplying drivetrain components to both privateer racers and factory-supported teams across Europe. The 202Y rear sprocket reflects that heritage: the tooth profile is CNC-machined to exacting tolerances, producing a surface finish that mates cleanly with a 520-pitch chain from the first link. Each colour variant is anodised rather than painted, meaning the finish penetrates the aluminium rather than sitting on top of it — it will not chip, flake or fade the way a lacquer can. The hard-anodised option takes this further still, producing a surface hardness that stands up to the abrasive conditions of repeated track days without demanding early replacement.\u003c\/p\u003e\u003cp\u003eThe eight colour choices are not an afterthought. Whether you are building a race-replica livery around your S1000RR's M Motorsport bodywork or simply want a subtle silver or black sprocket that disappears into the drivetrain, the range covers every taste. This is the kind of detail-level attention to finish that separates a true performance component from a generic replacement part.\u003c\/p\u003e\u003ch2\u003eGearing Strategy\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count is one of the simplest and most cost-effective tuning decisions available to a BMW S-series rider. The Sitta 202Y makes that choice accessible across a wide spectrum:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSmaller counts (37-42 teeth) reduce the final-drive ratio, raising top speed and lowering engine revs at motorway cruising speeds — ideal for high-speed circuits or long-distance road riding.\u003c\/li\u003e\n\u003cli\u003eLarger counts (43-47 teeth) increase the final-drive ratio, sharpening acceleration out of slow corners and making the bike feel more agile and responsive — the preferred choice for tight, technical track layouts or spirited back-road riding.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eBecause the 202Y is available across all eleven counts in a single quality tier, you can experiment with different ratios without investing in a new sprocket at each step.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 202Y is engineered exclusively for 520-pitch chains and fits the following BMW models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW S1000RR K46 (model years 2009 – 2018)\u003c\/li\u003e\n\u003cli\u003eBMW S1000XR (model years 2015 – 2018)\u003c\/li\u003e\n\u003cli\u003eBMW S1000R (model years 2014 – 2018)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSprocket carrier pattern: 110\/131 – 5-hole.

Aluminium Rear Sprocket for BMW HP4, HP4 Race \u0026 S1000RR HP Forged Wheel – 37-47 Teeth, 520 Pitch (204Y)","description":"\u003cp\u003eWhen the drivetrain is the last thing you want to think about mid-corner, the Sitta 204Y aluminium rear sprocket delivers the confidence to focus entirely on the riding. Precision-manufactured from high-grade aluminium and available in eleven tooth counts from 37 to 47, this sprocket is engineered specifically for the BMW HP4, HP4 Race, and S1000RR fitted with the HP forged wheel — giving you exact, repeatable power transfer whether you are chasing lap times or carving fast roads.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighs just 350 g at size 45, reducing unsprung mass for sharper steering response and faster acceleration.\u003c\/li\u003e\n\u003cli\u003e520 pitch specification, optimised for performance and racing use on the HP4 and HP4 Race platform.\u003c\/li\u003e\n\u003cli\u003eEleven tooth options spanning 37 to 47 teeth allow precise gearing adjustment to suit your riding style, circuit layout or road conditions.\u003c\/li\u003e\n\u003cli\u003eCarrier pattern: 70\/100-5 hole — matches the BMW HP forged wheel carrier for accurate, straightforward fitting.\u003c\/li\u003e\n\u003cli\u003eAvailable in eight anodised finishes including hard-anodised, which outlasts standard anodising and resists wear under sustained high-load conditions.\u003c\/li\u003e\n\u003cli\u003ePart number 204Y guarantees an exact reference for ordering and workshop records.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing Strategy: Choosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eThe tooth count you select has a direct and measurable effect on how your BMW HP4 or S1000RR behaves. Understanding the trade-offs lets you extract the most from Sitta's broad 37-47 tooth range.\u003c\/p\u003e\u003cp\u003eA smaller sprocket in the 37-42 tooth range shortens overall gearing, raising top speed and reducing engine revs at motorway cruise — the preferred choice for high-speed circuits with long straights such as Hockenheim or the Autobahn runs.\u003c\/p\u003e\u003cp\u003eStepping up to 43-47 teeth lengthens the effective gearing ratio, sharpening acceleration out of tight corners and making the bike feel more agile through technical sections. This is the setup favoured on shorter, more technical circuits or for riders who want a more responsive throttle on twisting roads.\u003c\/p\u003e\u003cp\u003eWith eleven discrete options, the Sitta 204Y lets you dial in the precise character you need rather than accepting a compromise.\u003c\/p\u003e\u003ch2\u003eConstruction \u0026amp; Finish Quality\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 204Y from high-quality aluminium, balancing structural integrity with the lowest possible rotational weight. The anodising options are not merely cosmetic: hard-anodising in particular creates a surface layer that is significantly harder than standard anodising, extending service life when the sprocket is used hard on track. The remaining seven colour finishes — silver, black, red, blue, gold, orange, and green — are standard anodised and offer a clean, corrosion-resistant surface suited to road and occasional track use.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 204Y rear sprocket is designed exclusively for the following BMW models equipped with the 520 pitch chain conversion:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW HP4 (all years)\u003c\/li\u003e\n\u003cli\u003eBMW HP4 Race\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR fitted with HP forged wheel\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCarrier specification: 70\/100-5 hole.

Aluminium Rear Sprocket Suzuki GSX-R 600 \u0026 750 (2003-2010) – 520 Pitch, 37-47 Teeth (201Z)","description":"\u003cp\u003eCrafted from high-grade aluminium and offered in a palette of striking anodised finishes, the Sitta 201Z rear sprocket brings race-proven heritage and meticulous engineering to the drivetrain of your Suzuki GSX-R 600 or GSX-R 750 (2003–2010). Where lesser sprockets compromise on finish or longevity, the 201Z delivers both — a component that looks as precise as it performs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHigh-grade aluminium construction keeps weight to just 350 g (size 45), reducing unsprung mass for sharper throttle response and improved agility.\u003c\/li\u003e\n\u003cli\u003e520 pitch optimised for performance and racing applications — lighter and faster than the stock 530 conversion.\u003c\/li\u003e\n\u003cli\u003eEleven tooth options from 37 to 47 teeth let you dial in the exact gearing ratio for your riding style, circuit or road conditions.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option offers superior surface hardness and wear resistance compared to standard anodising — ideal for high-mileage or track use.\u003c\/li\u003e\n\u003cli\u003eAvailable in multiple colours — hard-anodised, black, silver, blue, red, green, orange and gold — so your drivetrain reflects your build's character.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier dimensions of 120 x 140 mm, 5-bolt pattern, 10.50 mm bolt holes ensure precise, straightforward fitment with no modification required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has built its reputation on sprockets that satisfy both the scrutineer's eye and the stopwatch. The 201Z is machined to tight tolerances, and every anodised colour variant — from understated silver to vivid gold — is applied as a proper hard-anodised layer rather than a cosmetic dip. Hard-anodising penetrates the aluminium surface rather than sitting on top of it, producing a finish that resists corrosion, chain wear and road debris far longer than conventional anodising. The result is a sprocket that looks purposeful from new and stays that way through a full season of hard riding.\u003c\/p\u003e\u003ch2\u003eGearing Strategy\u003c\/h2\u003e\u003cp\u003eChoosing the right tooth count is one of the most cost-effective performance adjustments you can make to any GSX-R. Fitting a smaller sprocket in the 37–42 tooth range shortens overall gearing, raising top speed and easing engine revs at motorway pace — a popular choice for track days on longer circuits. Moving to the 43–47 tooth range lengthens gearing in the traditional sense, sharpening acceleration out of slower corners and giving the engine more to work with on technical layouts or spirited road riding. The 201Z's eleven available tooth counts mean you can find the precise ratio that suits your chassis setup, tyre choice and preferred circuit or road.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201Z rear sprocket is designed exclusively for the following models and is compatible with 520 pitch chains only:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuzuki GSX-R 600 (model years 2003–2010)\u003c\/li\u003e\n\u003cli\u003eSuzuki GSX-R 750 (model years 2003–2010)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSprocket carrier interface: 120 x 140 mm, 5-bolt pattern, bolt hole diameter 10.50 mm.

Rear Sprocket for PVM Sprocket Carrier (201J) – 37-47 Teeth, 520 Pitch","description":"\u003cp\u003eWhen lap times matter, every gramme counts. The Sitta 201J aluminium rear sprocket is engineered for riders who demand race-ready precision from their drivetrain — weighing just 350 g at size 45 and available in tooth counts from 37 to 47, it lets you dial in exactly the gearing your track session or sprint stage demands. Paired with the PVM sprocket carrier via an 80\/100-5 bolt pattern, installation is clean and positive every time.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUltralight aluminium construction — only 350 g at size 45, keeping unsprung weight to a minimum for sharper turn-in and faster acceleration response.\u003c\/li\u003e\n\u003cli\u003e520-pitch specification, optimised for performance and racing use where reduced chain mass translates directly into drivetrain efficiency.\u003c\/li\u003e\n\u003cli\u003eWide tooth-count range from 37 to 47 teeth, covering everything from high-speed track configurations to aggressive short-circuit gearing.\u003c\/li\u003e\n\u003cli\u003eEight colour options including hard-anodised finish — more durable than standard anodising — plus black, silver, gold, red, blue, orange and green for a personalised build.\u003c\/li\u003e\n\u003cli\u003e80\/100-5 hole pattern engineered specifically for PVM sprocket carriers, ensuring precise alignment and a rattle-free fitment.\u003c\/li\u003e\n\u003cli\u003eHigh resistance to wear under sustained heavy load, maintaining consistent power transfer across race distances and spirited road riding alike.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing Strategy: Choosing Your Tooth Count\u003c\/h2\u003e\u003cp\u003eThe Sitta 201J gives you genuine flexibility to tailor your motorcycle's character to the circuit or road section in front of you. Understanding how tooth count affects behaviour makes the choice straightforward.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket in the 37-to-42-tooth range raises overall gearing, reducing engine rpm at a given road speed and extending your top speed — the sensible choice for fast, flowing circuits with long straights or motorway-heavy touring stages.\u003c\/p\u003e\u003cp\u003eStepping up to the 43-to-47-tooth range lowers overall gearing for snappier acceleration and more responsive throttle feel out of tight corners — exactly what short, technical circuits and twisting mountain roads reward. With eleven tooth-count options across a single part number, you can carry a spare sprocket pre-selected for a different venue without changing any other component.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 201J from high-grade aluminium, balancing the tensile strength required to survive repeated hard acceleration loads against the weight savings that make a measurable difference on track. The hard-anodised option goes through a thicker, denser oxide layer than conventional anodising, resisting surface abrasion and chain-induced wear for a significantly longer service life — a worthwhile upgrade for riders who cover high annual mileage or compete regularly. All other colour options receive a quality anodised finish that protects the alloy while delivering a consistent, factory-level appearance.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201J is designed exclusively for motorcycles fitted with a PVM sprocket carrier.

The aluminium billet is machined to close tolerances, producing a tooth profile that engages your chain cleanly from cold starts through to sustained high-speed running. Each colour variant is anodised rather than painted, meaning the finish penetrates the aluminium surface rather than sitting on top of it — the result is a component that stays looking purposeful long after lesser sprockets have faded or flaked.\u003c\/p\u003e\u003cp\u003eThe hard-anodised option takes this further still. By deepening the oxidation layer, it achieves a surface hardness that measurably outperforms standard anodising, making it the first choice for riders who cover serious mileage or spend extended time on track. Yet even the standard anodised finishes — from the understated silver to the vivid orange and gold — bring a level of visual intention rarely seen on a drivetrain component.\u003c\/p\u003e\u003ch2\u003eGearing Strategy: Choosing Your Tooth Count\u003c\/h2\u003e\u003cp\u003eThe 201M's range of 37 to 48 teeth gives GSX-R riders genuine flexibility to tailor the bike's character to their riding environment. A smaller sprocket in the 37-to-42 tooth range lowers overall gearing, raising top speed and easing engine revs on long, open sections — useful for circuit configurations with extended straights or for relaxed motorway touring. Moving to the 43-to-48 tooth range tightens gearing, sharpening acceleration out of slower corners and making the GSX-R feel more responsive in technical sections. Many track-day riders run a larger rear sprocket as a simple, reversible way to transform a street-biased setup into a more aggressive track tool without touching suspension or electronics.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201M is engineered exclusively for the following models and is compatible with 520 pitch chains only:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuzuki GSX-R 600 (2011 – 2016)\u003c\/li\u003e\n\u003cli\u003eSuzuki GSX-R 750 (2011 – 2016)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSprocket carrier: 110\/130 — 6-bolt pattern.

Aluminium Rear Sprocket Suzuki GSX-R 1000 (2009-2023) – 520 Pitch, 37-48 Teeth (201M)","description":"\u003cp\u003eA straightforward upgrade that rewards daily riders and weekend track-day enthusiasts alike, the Sitta 201M aluminium rear sprocket gives your Suzuki GSX-R 1000 a noticeable reduction in unsprung and rotating mass without asking you to spend beyond reason. Weighing just 350 g at 45 teeth, it slots directly onto the stock carrier and lets you fine-tune your gearing with a simple sprocket swap rather than a full drivetrain overhaul.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction — 350 g at size 45 — reduces rotating mass and sharpens throttle response on both road and track\u003c\/li\u003e\n\u003cli\u003eWide tooth selection from 37 to 48 teeth in 520 pitch covers every gearing preference, from motorway cruising to tight circuit work\u003c\/li\u003e\n\u003cli\u003eAvailable in eight anodised colours — silver, black, hard-anodised, red, blue, orange, gold and green — the hard-anodised finish offering superior durability over standard anodising\u003c\/li\u003e\n\u003cli\u003eCarrier specification 110\/130-6 bolt pattern ensures a precise, rattle-free fit and makes installation straightforward with standard workshop tools\u003c\/li\u003e\n\u003cli\u003ePrecision-machined tooth profiles promote even chain engagement, minimising wear on both the sprocket and the chain\u003c\/li\u003e\n\u003cli\u003ePart number 201M — a well-established Sitta reference stocked for quick despatch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing, Road Use and Track Use\u003c\/h2\u003e\u003cp\u003eChoosing the right tooth count is the single easiest way to tailor the GSX-R 1000's character to how you actually ride. Smaller sprockets in the 37-42 teeth range produce a taller overall gearing ratio: engine revs drop at a given road speed, top speed ceiling rises, and the bike feels more relaxed on long motorway runs. Larger sprockets in the 43-48 teeth range shorten the gearing ratio, delivering snappier acceleration out of slow corners and a more immediate, agile feel through technical sections — the configuration most track riders reach for when circuit lap times matter.\u003c\/p\u003e\u003cp\u003eFor mixed road riders who occasionally visit a circuit, a mid-range tooth count such as 42 or 43 typically offers a well-rounded compromise: adequate top-end for A-road riding and enough drive to make overtakes feel effortless. Because swapping a rear sprocket is a modest job, many GSX-R 1000 owners keep a second sprocket on the shelf for dedicated track days.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta machines the 201M from high-grade aluminium chosen for its balance of tensile strength and low density. The standard anodised options — silver, black, red, blue, orange, gold and green — provide a durable surface layer that resists corrosion and light abrasion. The hard-anodised variant goes further: the electrochemical process penetrates deeper into the aluminium matrix, producing a surface hardness that measurably outlasts conventional anodising under the abrasive conditions of chain contact and road grime. If longevity between service intervals is your priority, the hard-anodised option is the practical choice regardless of colour preference.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201M rear sprocket is designed and manufactured specifically for the following application:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuzuki GSX-R 1000 — model years 2009 to 2023\u003c\/li\u003e\n\u003cli\u003e520 pitch chain only — confirm your chain pitch before ordering if you have already converted your drivetrain\u003c\/li\u003e\n\u003cli\u003eCarrier bolt pattern: 110\/130 — 6 bolt\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIf you are running a 525 or 530 pitch chain in standard configuration, a chain conversion to 520 pitch is required before fitting this sprocket.

Aluminium Rear Sprocket Yamaha YZF-R1 (2003-2014) 201M – 37-48 Teeth, 520 Pitch","description":"\u003cp\u003eCrafted from precision-machined aluminium and finished in a palette of eight anodised colours, the Sitta 201M rear sprocket brings race-bred heritage and unmistakable style to the Yamaha YZF-R1 drivetrain. Whether you are chasing lap times or simply demanding the best from a decade-old superbike platform, this is a sprocket built to the same exacting standards that have made Sitta a trusted name in European motorsport.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighing just 350 g at 45 teeth — reducing unsprung rotational mass for sharper throttle response and improved handling.\u003c\/li\u003e\n\u003cli\u003eEight finish options including silver, black, hard-anodised, red, blue, gold, green and orange — hard-anodising delivering significantly greater surface hardness and longevity than standard anodising.\u003c\/li\u003e\n\u003cli\u003eBroad tooth range from 37 to 48 teeth on a 520 pitch, allowing precise gearing adjustment for road sport or track use.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier pattern 110\/130-6 bolt for accurate, straightforward installation on the YZF-R1 hub.\u003c\/li\u003e\n\u003cli\u003eEngineered for high-load durability — the alloy and surface treatment resist wear even under sustained track conditions.\u003c\/li\u003e\n\u003cli\u003ePart number 201M — a Sitta catalogue reference with a long competition heritage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDialling In Your Gearing\u003c\/h2\u003e\u003cp\u003eThe 520 pitch and twelve tooth options make the 201M one of the most versatile sprockets available for the R1 platform. Selecting a smaller sprocket in the 37-to-42 tooth range lengthens the overall gearing ratio, raising top speed and reducing engine revs at motorway pace — ideal for open circuits or long touring stints. Moving up to the 43-to-48 tooth range shortens the ratio, sharpening acceleration out of slow corners and making the bike feel more responsive through technical sections. Pairing a new rear sprocket with a matched front sprocket and fresh 520 chain will unlock the full benefit of any ratio change.\u003c\/p\u003e\u003ch2\u003eFinish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has been producing drivetrain components for road and competition machines across Europe for decades. The 201M reflects that lineage: tolerances are held tight, the tooth profile is optimised for 520 chain engagement, and every colour option receives a consistent, hard-wearing anodised layer. The hard-anodised variant in particular offers a surface that resists abrasion from chain contact and road debris far beyond what standard anodising can provide, making it the finish of choice for riders who log serious mileage.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R1 — model years 2003 to

measurable performance gains without the premium price of exotic materials, the Sitta 201M is the straightforward, sensible upgrade. Weighing just 350 g at size 45, this precision-machined aluminium sprocket covers every tooth count from 37 to 48 and fits every R6 variant from the 2003 RJ11 through to the 2026 RJ27 — making it one of the most versatile and accessible gearing solutions available for this chassis.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction at only 350 g (size 45), reducing unsprung and rotating mass for sharper throttle response\u003c\/li\u003e\n\u003cli\u003eFull 520 pitch compatibility, optimised for performance road and track use\u003c\/li\u003e\n\u003cli\u003eTwelve tooth options from 37 to 48 teeth, allowing precise gearing tuning for any riding style or circuit\u003c\/li\u003e\n\u003cli\u003eSprocket carrier pattern 110\/130-6 bolt for accurate, straightforward fitment\u003c\/li\u003e\n\u003cli\u003eAvailable in eight finishes: silver, black, hard-anodised, red, blue, gold, orange and green — hard-anodised offering greater surface durability than standard anodising\u003c\/li\u003e\n\u003cli\u003eEngineered for consistent power transfer and low wear even under sustained high load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing — Choosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eSelecting the correct rear sprocket tooth count has a direct influence on the way the R6 pulls through the rev range. It is worth understanding the trade-off before ordering.\u003c\/p\u003e\u003cp\u003eA smaller sprocket (37–42 teeth) lowers the overall gearing ratio, raising top speed and reducing engine revs at motorway pace — useful for long-distance road riding or high-speed circuits where sustained full-throttle stretches dominate. A larger sprocket (43–48 teeth) raises the overall ratio, sharpening acceleration and making the bike feel more aggressive out of slow and medium-speed corners — the preferred choice for technical circuits and enthusiastic road riding where drive out of bends matters more than outright top speed.\u003c\/p\u003e\u003cp\u003eThe Sitta 201M range covers the full spectrum, so whether you are chasing lap times at a track day or simply want a sprocket that suits your daily commute and weekend mountain roads, the right option is available without sourcing a different product entirely.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eThe 201M is machined from high-grade aluminium, balancing the need for low weight against the durability demands of a 520 pitch chain running under race-derived loads. The hard-anodised finish option provides a harder surface layer than conventional anodising, extending the service life of the teeth and retaining the visual finish longer under chain contact and road grime. The remaining seven colour options — silver, black, red, blue, gold, orange and green — are standard anodised, offering a clean, corrosion-resistant surface that holds its colour well over normal service intervals.\u003c\/p\u003e\u003cp\u003eThe 110\/130-6 bolt carrier pattern ensures the sprocket locates precisely on the standard R6 hub with no modification required, keeping installation time short and fitment repeatable across the full 2003–2026 model range.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201M rear sprocket is designed and confirmed for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R6 RJ11 (2003–2004)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R6 RJ15 (2006–2007)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R6 RJ27 (2008–2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible with 520 pitch chains only.

engineering and a striking eight-colour palette to the Yamaha YZF-R1 and YZF-R1M, covering every RN32, RN49 and RN65 chassis from 2015 through 2026. Weighing just 350 g in 45-tooth trim, it is the kind of component that earns its place on a World Superbike-derived machine — lightweight where it matters, precise in its fit, and available in a tooth range wide enough to transform the character of the bike entirely.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUltra-light aluminium construction — only 350 g (45-tooth size), reducing unsprung and rotating mass for sharper throttle response\u003c\/li\u003e\n\u003cli\u003eEight anodised finishes available: silver, black, hard-anodised, blue, red, gold, green and orange — hard-anodised option outlasts standard anodising for extended service life\u003c\/li\u003e\n\u003cli\u003eFull tooth range from 37 to 47 teeth in 520 pitch, allowing precise gearing adjustment for road or track use\u003c\/li\u003e\n\u003cli\u003eSprocket carrier spec 112\/138 — 5-bolt mount for accurate, rattle-free installation on RN32, RN49 and RN65 frames\u003c\/li\u003e\n\u003cli\u003eEngineered for low wear under sustained high load, suitable for race-track duty and spirited road riding alike\u003c\/li\u003e\n\u003cli\u003ePart number 202M — a catalogued Sitta reference for straightforward ordering and reordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFinish, Design and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has supplied drivetrain components to the racing paddock for decades, and the 202M reflects that lineage in every detail. The anodised surface does more than look the part: it hardens the aluminium against the constant abrasion of chain contact and the thermal cycling that comes with track sessions. The hard-anodised variant goes a step further, producing a surface harder than standard anodising and significantly more resistant to wear — an important consideration when you are running a lightweight 520-pitch setup at sustained high revs.\u003c\/p\u003e\u003cp\u003eThe colour range — silver, black, hard-anodised, blue, red, gold, green and orange — means the 202M sits naturally alongside aftermarket wheels, caliper finishes and frame details without looking like an afterthought. Each finish is applied with the same dimensional precision, so whichever colour you select, the sprocket runs true on the 112\/138 five-bolt carrier.\u003c\/p\u003e\u003ch2\u003eGearing Strategy\u003c\/h2\u003e\u003cp\u003eThe 520-pitch chain standard is the natural choice for a performance-oriented R1 build, offering a meaningful weight saving over the stock 530 pitch while maintaining the tensile strength needed for track use. Within that pitch, the 202M gives you eleven tooth options to dial in exactly the gearing character you want.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSmaller sprockets (37-42 teeth): shorter overall gearing, raising top speed potential and reducing engine revs on fast, open circuits or motorway stretches\u003c\/li\u003e\n\u003cli\u003eLarger sprockets (43-47 teeth): taller overall gearing, sharpening acceleration out of slow corners and making the power more accessible in technical, stop-start sections\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe right choice depends on your circuit, riding style and whether the bike also sees road use — but the range covered by the 202M means you can fine-tune without compromise.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp;

long days on road or track.

By reducing unsprung and rotating weight at the rear wheel, you sharpen the V4's already-crisp throttle response and reduce drivetrain inertia through fast direction changes. The breadth of available tooth counts — from a short 37 to a tall 46 — means you can dial gearing precisely for short, technical tracks demanding rapid acceleration or longer, faster circuits where top-speed matters most. Switching between 520 and 525 pitch also gives you the flexibility to align with a full chain kit conversion or retain your existing setup.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eSitta has manufactured drivetrain components for competition motorcycles for decades, and the 206D reflects that pedigree. The hard-anodising process penetrates the aluminium surface rather than simply coating it, creating a hardened layer that resists the abrasive wear generated by high-tension chain contact at race RPM.

The hard-anodising process penetrates the aluminium substrate rather than sitting on top of it, creating a surface layer that is harder and denser than standard anodising. The result is a sprocket that resists the grinding wear of high-power chain loads far longer while retaining the weight advantage that makes aluminium the material of choice at circuit level. The finish also gives the sprocket a purposeful, uniform appearance that suits the visual language of the Panigale 1299 perfectly.\u003c\/p\u003e\u003ch2\u003eOn Road and Track\u003c\/h2\u003e\u003cp\u003eAt 625 g for a 45-tooth unit, the 206D sits well below the weight of an equivalent steel sprocket. That reduction in rotating mass is felt immediately in how the 1299's engine revs and how the chassis responds to mid-corner throttle inputs. Teams running the Panigale in Superbike or track-day trim frequently choose a shorter rear sprocket — stepping from 41 to 43 or 44 teeth — to sharpen exit drive, while road riders may prefer a taller setup for relaxed motorway cruising. With ten tooth options in the range, the right compromise is always within reach.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is engineered specifically for the Ducati Panigale 1299 and 1299 S produced between 2015 and 2018.

Moving to the upper end, between 43 and 47 teeth, shortens gearing, sharpening acceleration out of tight corners and delivering a more aggressive throttle response throughout the rev range.

aluminium rear sprocket for the Ducati Panigale 1199\/R\/S cuts unsprung rotational mass without sacrificing the structural integrity a 1199 superbike requires. At just 625 g in the 45-tooth configuration, this is a precision drivetrain component that sharpens throttle response, improves acceleration feel and lets you dial in your exact gearing for every circuit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard-anodised aluminium construction delivers a surface hardness that outlasts conventionally anodised sprockets, resisting wear and corrosion even under repeated track-day punishment.\u003c\/li\u003e\n\u003cli\u003eAvailable in ten tooth counts from 37 to 46, covering every gearing strategy from short-circuit acceleration to longer, faster circuits where top-speed ratios matter.\u003c\/li\u003e\n\u003cli\u003eCompatible with both 520 and 525 pitch chains, giving you the freedom to stay on your current chain standard or convert to the lighter 520 pitch for additional drivetrain weight savings.\u003c\/li\u003e\n\u003cli\u003eWeighs just 625 g at 45 teeth — a meaningful reduction in unsprung and rotating mass that sharpens the Panigale 1199's already razor-edged throttle response.\u003c\/li\u003e\n\u003cli\u003e6-bolt 60\/110 sprocket carrier pattern ensures a precise, rattle-free fit on the standard Ducati Panigale 1199 hub with no modification required.\u003c\/li\u003e\n\u003cli\u003ePart number 206D — a dedicated fitment for the Panigale 1199 family, not a universal compromise.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTrack Performance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eThe Ducati Panigale 1199 is a machine built around peak performance, and its drivetrain deserves components held to the same standard. Sitta machines this rear sprocket from high-grade aluminium billet and subjects it to a hard-anodising process that creates a surface layer significantly harder and more abrasion-resistant than standard anodising. The result is a sprocket that maintains clean tooth geometry through extended track use, keeping chain engagement consistent and reducing the micro-vibrations that accompany a worn drivetrain.\u003c\/p\u003e\u003cp\u003eThe 6-bolt 60\/110 carrier interface is the same pattern used by OEM Ducati components, so installation is straightforward and the sprocket seats exactly where it should — no shimming, no improvisation. Whether you are switching pitch from 525 to 520 for a weight-reduction build or simply replacing a worn sprocket with a correctly specced upgrade, the 206D slots in with the precision the Panigale platform demands.\u003c\/p\u003e\u003ch2\u003eGearing Strategy for the Panigale 1199\u003c\/h2\u003e\u003cp\u003eChoosing between 37 and 46 teeth gives you a wide spread of final drive ratios. Dropping to a smaller rear sprocket raises top speed and suits longer tracks with extended straights; stepping up to a larger count sharpens acceleration out of tight chicanes and hairpins. Because the Sitta 206D is available in half-tooth increments across the full range in both 520 and 525 pitch, you can fine-tune your ratio without being forced to change front sprockets at the same time — a practical advantage when setting up on the grid.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDucati Panigale 1199 (2012-2017)\u003c\/li\u003e\n\u003cli\u003eDucati Panigale 1199 R (2012-2017)\u003c\/li\u003e\n\u003cli\u003eDucati Panigale 1199 S (2012-2017)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSitta\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e206D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eAluminium, hard-anodised\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAvailable Teeth\u003c\/th\u003e\n\u003ctd\u003e37, 38, 39, 40, 41, 42, 43, 44, 45, 46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChain Pitch\u003c\/th\u003e\n\u003ctd\u003e520 \/ 525\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e625 g (45-tooth)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSprocket Carrier\u003c\/th\u003e\n\u003ctd\u003e6-bolt, 60\/110\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eDucati Panigale 1199\/R\/S, 2012-2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Sitta","offers":[{"title":"37 \/520 \/ Hard-Anodised","offer_id":53167002616074,"sku":"si206D37od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"37 \/525 \/ Hard-Anodised","offer_id":53167002648842,"sku":"si206D37od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"38 \/520 \/ Hard-Anodised","offer_id":53167002681610,"sku":"si206D38od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"38 \/525 \/ Hard-Anodised","offer_id":53167002714378,"sku":"si206D38od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"39 \/520 \/ Hard-Anodised","offer_id":53167002747146,"sku":"si206D39od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"39 \/525 \/ Hard-Anodised","offer_id":53167002779914,"sku":"si206D39od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"40 \/520 \/ Hard-Anodised","offer_id":53167002812682,"sku":"si206D40od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"40 \/525 \/ Hard-Anodised","offer_id":53167002845450,"sku":"si206D40od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"41 \/520 \/ Hard-Anodised","offer_id":53167002878218,"sku":"si206D41od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"41 \/525 \/ Hard-Anodised","offer_id":53167002910986,"sku":"si206D41od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"42 \/520 \/ Hard-Anodised","offer_id":53167002943754,"sku":"si206D42od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"42 \/525 \/ Hard-Anodised","offer_id":53167002976522,"sku":"si206D42od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"43 \/520 \/ Hard-Anodised","offer_id":53167003009290,"sku":"si206D43od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"43 \/525 \/ Hard-Anodised","offer_id":53167003042058,"sku":"si206D43od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"44 \/520 \/ Hard-Anodised","offer_id":53167003074826,"sku":"si206D44od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"44 \/525 \/ Hard-Anodised","offer_id":53167003107594,"sku":"si206D44od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"45 \/520 \/ Hard-Anodised","offer_id":53167003140362,"sku":"si206D45od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"45 \/525 \/ Hard-Anodised","offer_id":53167003173130,"sku":"si206D45od525","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"46 \/520 \/ Hard-Anodised","offer_id":53167003205898,"sku":"si206D46od520","price":164.91,"currency_code":"EUR","in_stock":false},{"title":"46 \/525 \/ Hard-Anodised","offer_id":53167003238666,"sku":"si206D46od525","price":164.91,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/NEWIMG_2298_26fee481-d727-413e-8914-e0f107711f04.png?v=1780787834"},{"product_id":"sitta-207y","title":"Sitta Aluminium Rear Sprocket BMW S1000RR K67 (2019-2026) 207Y – 37-47 Teeth, 520 Pitch","description":"\u003cp\u003eKeeping your BMW S1000RR K67 running smoothly day after day demands drivetrain components that genuinely earn their place.

Aluminium Rear Sprocket Honda CBR 1000 RR-R SC82 (2020-2026) (201N) – 37-48 Teeth, 520 Pitch","description":"\u003cp\u003eA direct-fit rear sprocket that works as hard on a Sunday road ride as it does on track day — the Sitta 201N is precision-machined from high-grade aluminium to give your Honda CBR 1000 RR-R SC82 reliable power transfer, low rotating mass and the gearing flexibility to suit your riding style straight out of the box.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHigh-grade aluminium construction delivers an excellent strength-to-weight ratio, reducing unsprung and rotating mass without sacrificing durability under sustained hard use.\u003c\/li\u003e\n\u003cli\u003eAvailable in twelve tooth counts from 37 to 48, covering every gearing preference from relaxed motorway cruising to aggressive short-circuit acceleration.\u003c\/li\u003e\n\u003cli\u003e520 pitch specification — optimised for performance applications and compatible with 520 conversion chain kits.\u003c\/li\u003e\n\u003cli\u003eEight anodised colour options including hard-anodised finish (more wear-resistant than standard anodising), giving you both protection and personalised aesthetics.\u003c\/li\u003e\n\u003cli\u003ePrecision-machined for a direct, rattle-free fit to the Honda CBR 1000 RR-R SC82 rear hub — no modification required.\u003c\/li\u003e\n\u003cli\u003eConsistent tooth geometry promotes even chain wear, extending the service life of both the chain and the front sprocket.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eChoosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eGearing selection has a real impact on how your CBR 1000 RR-R delivers its power. Understanding the trade-offs lets you optimise for your most common riding environment without compromise.\u003c\/p\u003e\u003cp\u003eA smaller sprocket in the 37-42 tooth range shortens the overall gearing ratio, which translates to a higher top speed and reduced engine revs at motorway speeds — ideal if you cover long, open stretches or want a more relaxed power delivery for road use.\u003c\/p\u003e\u003cp\u003eMoving up to the 43-48 tooth range lengthens the ratio, sharpening acceleration out of corners and improving low-speed agility. This is the preferred choice for track days and twisty road work where exit speed matters more than outright top end.\u003c\/p\u003e\u003cp\u003eThe Sitta 201N range lets you dial in exactly the balance you want — and if your riding evolves, swapping to a different tooth count is a straightforward workshop job.\u003c\/p\u003e\u003ch2\u003eColour Options\u003c\/h2\u003e\u003cp\u003eThe 201N is available in eight finishes: silver, black, hard-anodised, gold, blue, red, green and orange. The hard-anodised option undergoes a deeper electrochemical treatment than standard anodising, producing a harder surface layer that resists abrasion and corrosion particularly well — a sensible choice for year-round road use or high-mileage applications where longevity matters as much as looks.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is

The material resists the deformation and fatigue cracking that cheaper alloys can exhibit under the cyclical loading of a high-revving inline-four. The hard-anodised surface treatment, where selected, penetrates the aluminium substrate rather than simply coating it, producing a finish that outlasts standard anodising in abrasive conditions and resists the oil and chain lubricant contamination inevitable in real-world use.\u003c\/p\u003e\u003cp\u003eThe 520 pitch teeth are profiled to optimise engagement with the chain rollers, distributing

Pairing it with a front sprocket change extends the range of ratios even further.\u003c\/p\u003e\u003ch2\u003eFinish \u0026amp; Colour Options\u003c\/h2\u003e\u003cp\u003eAll eight finishes are available across the full tooth range. The hard-anodised option offers superior surface hardness compared to conventional anodising, making it the preferred choice for riders who complete regular track days and want a sprocket that keeps its appearance under sustained use. The remaining colours — silver, black, red, blue, gold, orange and green — are standard anodised and give plenty of scope to coordinate with the RS 660's bodywork or wheel

confidence-inspiring durability across the full riding day.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard-anodised aluminium construction resists abrasion,

V4\/S\/R cush drive carrier with no modifications required.\u003c\/li\u003e\n\u003cli\u003ePurpose-designed for the Ducati Panigale V4, V4 S and V4 R from 2018 through 2024, covering all major

hard-anodising process that significantly increases surface hardness beyond standard anodising. The result is a component that not only weighs considerably less than the factory part but actively resists the micro-abrasion that degrades standard carriers over time. Whether you are completing back-to-back track days or logging long-distance road miles, the hard-anodised surface maintains its integrity and appearance across the life of the component.\u003c\/p\u003e\u003cp\u003eThe weight reduction achieved by replacing the original cush drive carrier with the Sitta unit contributes directly to reduced rotating mass in the drivetrain. On a high-performance machine like the Panigale V4, even modest reductions in rotating unsprung mass translate into a more immediate throttle response, improved acceleration feel and a more connected ride — qualities that become increasingly noticeable over the course of a long day in the saddle.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSitta designed the 206D02 to be a true plug-and-play component. It mounts directly in place of the OEM rear sprocket carrier using the standard fixings, requiring no drilling, re-machining or bespoke hardware. The fitment process is straightforward and accessible to any competent home mechanic or race-day technician looking to optimise the drivetrain between sessions.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis carrier is specifically developed and verified for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDucati Panigale V4 (2018-2024)\u003c\/li\u003e\n\u003cli\u003eDucati Panigale V4 S (2018-2024)\u003c\/li\u003e\n\u003cli\u003eDucati Panigale V4 R (2018-2024)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSitta\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e206D02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003ctd\u003eRear sprocket carrier (cush drive carrier)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eHigh-grade aluminium, hard-anodised\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eHard-anodised\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eDucati Panigale V4, V4 S, V4 R (2018-2024)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInstallation\u003c\/th\u003e\n\u003ctd\u003ePlug-and-play, direct OEM replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Sitta","offers":[{"title":"Hard-Anodised","offer_id":53167363424522,"sku":"206D02","price":161.01,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/206D02.png?v=1780796273"},{"product_id":"sitta-201u","title":"Sitta Aluminium Rear Sprocket Triumph Street Triple 765 S \/ R \/ RS \/ Moto2 \u0026 Daytona 765 Moto2 (2017-2026) – 37-48 Teeth, 520 Pitch (201U)","description":"\u003cp\u003eWhen lap times and power delivery matter most, drivetrain weight is the enemy.

Aluminium Rear Sprocket for Aprilia RS 660 (2020-2026) – 37-48 Teeth, 525 Pitch (202P)","description":"\u003cp\u003ePrecision-machined from high-grade aluminium, the Sitta Aluminium rear sprocket is built to a standard that serious RS 660 riders will immediately recognise. Available in 37 to 48 teeth at 525 pitch, and finished in eight distinct anodised colours, this sprocket delivers a measurable reduction in unsprung mass alongside a surface treatment that goes well beyond what standard anodising can offer — making it a genuine performance and longevity upgrade for both road and track use on the Aprilia RS 660 (2020-2026).\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard-anodised surface treatment provides significantly greater wear resistance and service life than conventional anodising, keeping the sprocket looking and performing at its best through extended use.\u003c\/li\u003e\n\u003cli\u003eLightweight aluminium construction weighs approximately 350 g in size 45, directly reducing unsprung mass and contributing to sharper, more responsive handling.\u003c\/li\u003e\n\u003cli\u003eWide tooth selection spanning 37 to 48 teeth on a 525 pitch gives you precise control over gearing — whether you want stronger acceleration for the track or a more relaxed top-gear pull for road touring.\u003c\/li\u003e\n\u003cli\u003eCompatible with both 520 and 525 chain versions, offering flexibility when paired with a chain conversion kit.\u003c\/li\u003e\n\u003cli\u003e5-hole sprocket carrier mounting pattern (100\/120-5 hole) ensures a straightforward, bolt-on installation with no modification required.\u003c\/li\u003e\n\u003cli\u003eAvailable in eight colours — silver, black, hard-anodised, red, gold, blue, orange and green — so the finish can be matched to any RS 660 livery.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eThe Sitta 202P rear sprocket is manufactured from aerospace-grade aluminium alloy and processed to tight tolerances throughout. The hard-anodising treatment applied as standard creates a surface layer that is considerably harder and denser than a conventional anodised finish, resisting wear from chain contact, road grit and the thermal cycles a motorcycle drivetrain generates in everyday use. The result is a sprocket that holds its tooth profile longer and resists corrosion far more effectively than budget alternatives — qualities you notice not just at purchase but over thousands of kilometres of use.\u003c\/p\u003e\u003ch2\u003ePerformance and Gearing\u003c\/h2\u003e\u003cp\u003eRear sprocket tooth count is one of the most cost-effective ways to tailor an RS 660's character. Moving to a higher tooth count shortens gearing, sharpening acceleration out of corners — a popular choice for circuit days where exit speed matters. Stepping down in teeth lengthens gearing, lowering engine revs at motorway speeds for a more comfortable touring setup. With twelve tooth options between 37 and 48, Sitta gives RS 660 owners the resolution to dial in exactly the right ratio for their riding style and preferred circuit or road profile.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is designed and confirmed to fit the Aprilia RS 660 across the full production run from 2020 to 2026. It is compatible with both 520 and 525 chain pitches. The 5-hole carrier interface (100\/120-5 hole pattern) matches the RS 660's rear wheel hub directly. Always confirm chain pitch compatibility with your existing or replacement chain before ordering.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eAttribute\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSitta\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart

meaningful effect on how your RSV4 accelerates and pulls through the rev range. A smaller sprocket shortens your overall gearing, raising top speed and reducing engine revs at motorway cruising speeds. A larger sprocket lengthens the gearing ratio, sharpening initial acceleration and mid-range punch — an advantage on technical circuits or twisty mountain roads where drive out of slow corners matters most.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e37–42 teeth: taller overall gearing — more top speed, relaxed cruising revs, ideal for fast open circuits and motorway touring\u003c\/li\u003e\n\u003cli\u003e43–48 teeth: shorter overall gearing — stronger acceleration, more responsive throttle, suited to tight technical tracks and spirited road riding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Finish\u003c\/h2\u003e\u003cp\u003eEvery Sitta 202P sprocket is machined from high-grade aluminium billet, keeping rotating mass low without sacrificing the tensile strength needed to cope with the RSV4's considerable torque output. The hard-anodised variant takes durability a step further: the treatment penetrates the aluminium surface to create a hardened outer layer that resists wear, corrosion, and chain abrasion more effectively than conventional anodising. For riders who want a balance of personalisation and protection, the full colour range — silver, black, red, gold, blue, orange, and green — is anodised to a consistent, chip-resistant standard.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is designed exclusively for the following models and is compatible with 525 pitch chains only:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 R (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2009-2026)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 1100 Factory (2009-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eImportant: this sprocket is produced exclusively in 525 pitch.

aluminium rear sprocket gives you full command of your gearing without adding unnecessary mass.

Understanding the trade-off lets you make a confident, informed choice before you order.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket in the 37–42 tooth range effectively raises overall gearing, reducing engine revs at a given road speed. This suits circuits with long straights or riders who want a more relaxed, highway-oriented character with a higher top speed potential.\u003c\/p\u003e\u003cp\u003eMoving up to the 43–48 tooth range shortens gearing, sharpening acceleration out of tight corners and improving agility in stop-start traffic or technical sections. This is the preferred setup for most track-focused applications on the SC82, where exit speed from corners matters more than outright top-end velocity.\u003c\/p\u003e\u003ch2\u003eColour Options and Finish Quality\u003c\/h2\u003e\u003cp\u003eThe 201N is available in eight finishes: silver, black, hard-anodised, gold, blue, red, green and orange. The hard-anodised variant deserves particular attention — the process creates a significantly harder surface layer than conventional anodising, resisting chain wear, abrasion and corrosion more effectively over the long term. All other colour options are anodised to a high standard and retain their appearance well under normal riding conditions.\u003c\/p\u003e\u003ch2\u003eFitment and

exacting tolerances, the Sitta 201N rear sprocket delivers a measurable reduction in unsprung and rotating mass — exactly where it counts on the Honda CBR 1000 RR.

The sprocket body is milled from high-grade aluminium billet, offering an excellent strength-to-weight ratio that outperforms cheaper cast alternatives. The tooth profile is precision-cut to mesh cleanly with 525 pitch chain from the first kilometre, reducing the bedding-in period and limiting early wear on both the sprocket and chain.\u003c\/p\u003e\u003cp\u003eThe hard-anodised variant deserves particular attention. Unlike conventional anodising, the hard-anodise process builds a denser, thicker oxide layer into the aluminium surface itself, dramatically improving abrasion resistance. Riders who cover high annual mileage or regularly use their CBR 1000 RR on track will find it outlasts a standard anodised sprocket by a considerable margin.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count is one of the most cost-effective performance tuning decisions available to a CBR 1000 RR owner. A smaller rear sprocket in the 37-42 tooth range lowers overall gearing, raising top speed and reducing engine revs at motorway cruising speeds — ideal for long-distance road riders and high-speed circuits such as Hockenheim or Mugello. Moving up to the 43-48 tooth range tightens the gearing ratio, sharpening acceleration out of slow corners and improving overall agility — the preferred choice for short, technical circuits or riders who prioritise drive over ultimate top speed. The Sitta 201N makes it straightforward to experiment with gearing without significant outlay.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201N rear sprocket is designed specifically for the following Honda CBR 1000 RR variants and years:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHonda CBR 1000 RR SC57 — model years 2004 to 2007\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR SC59 — model years 2008 to 2016\u003c\/li\u003e\n\u003cli\u003eHonda CBR 1000 RR SC77 — model years 2017 to 2019\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eImportant: this sprocket is compatible with 525 pitch chain only.

Getting it right costs nothing extra but makes a noticeable difference to everyday rideability.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket in the 37-to-42 tooth range raises overall gearing, reducing engine revs at motorway cruising speeds and extending top-end reach — a practical choice for riders who cover longer distances or want a more relaxed power delivery. Moving up to the 43-to-48 tooth range shortens the overall ratio, sharpening throttle response out of corners and improving pull from lower speeds. This suits more spirited riding, track days, or urban environments where brisk acceleration matters more than outright top speed.\u003c\/p\u003e\u003cp\u003eEither way, the Sitta 201N slots straight onto your existing carrier without any fuss, so experimenting with gearing is a straightforward and cost-effective way to personalise your ride.\u003c\/p\u003e\u003ch2\u003eConstruction and Finish\u003c\/h2\u003e\u003cp\u003eThe 201N is machined from high-grade aluminium, striking the practical balance between weight reduction and wear resistance that most road and occasional track riders actually need. The hard-anodised option is worth considering if longevity is a priority — this surface treatment penetrates deeper into the metal than standard anodising, resisting abrasion and corrosion more effectively over time. The remaining colour options — black, silver, blue, red, orange, gold and green — use a quality anodised finish that holds its appearance well under normal riding conditions and adds a clean visual accent to the drivetrain.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201N is engineered specifically for the following Honda models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHonda CBR 600 RR PC37 (2007-2008)\u003c\/li\u003e\n\u003cli\u003eHonda CBR 600 RR PC40 (2009-2016)\u003c\/li\u003e\n\u003cli\u003eHonda CBR 600 RR PC69 (2017-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThis sprocket is compatible with 525 pitch chains only.

Aluminium Rear Sprocket Yamaha YZF-R1 2003-2014 (201M) – 37-48 Teeth, 525 Pitch","description":"\u003cp\u003eCrafted from lightweight aluminium and finished in eight anodised colours, the Sitta 201M rear sprocket is engineered specifically for the Yamaha YZF-R1 (2003–2014). This is a sprocket that earns its place on the bike through precise manufacturing heritage and a finish that holds up under sustained track and road punishment alike.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePremium aluminium construction weighing approximately 350 g (at size 45) for an immediate reduction in unsprung mass without sacrificing structural integrity.\u003c\/li\u003e\n\u003cli\u003eEight finish options — silver, black, hard-anodised, red, blue, gold, green and orange — allowing a tailored visual match to your R1's livery. The hard-anodised variant offers superior surface hardness and longer service life compared to standard anodising.\u003c\/li\u003e\n\u003cli\u003eWide tooth selection from 37 to 48 teeth in 525 pitch, covering the full range from top-speed-biased gearing to aggressive acceleration setups.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier interface: 110\/130 – 6-hole bolt pattern for precise, rattle-free fitment on the YZF-R1 carrier.\u003c\/li\u003e\n\u003cli\u003eConsistent tooth profile geometry ensures low wear even under sustained high-load conditions, on circuit or on road.\u003c\/li\u003e\n\u003cli\u003ePart number 201M — a long-established Sitta reference, ensuring straightforward reordering and cross-referencing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has supplied drivetrain components to serious riders across Europe for decades, and the 201M reflects that accumulated expertise. The sprocket blank is machined to close tolerances, then anodised in the colour of your choice. The hard-anodised option is worth special mention: the electrolytic process penetrates deeper into the aluminium substrate than conventional anodising, producing a surface that resists abrasion from the chain side-plates far longer than a standard colour finish. Whether you are chasing lap times at a trackday or accumulating kilometres on a favourite road route, the finish you choose will perform proportionally to the demands placed on it.\u003c\/p\u003e\u003ch2\u003eChoosing the Right Gearing for Your Riding Style\u003c\/h2\u003e\u003cp\u003eThe tooth count you select shapes the entire character of the YZF-R1's drivetrain response. A smaller rear sprocket in the 37–42 tooth range lowers the overall gearing ratio, raising top speed and reducing engine revs at motorway cruising speeds — useful for long open-road stages or high-speed circuits. Moving up to the 43–48 tooth range tightens the gearing, sharpening throttle response out of slow corners and improving acceleration from low speeds, which suits technical circuits and twisting B-roads. The 201M's availability across the full 37–48 tooth spread means you can dial in exactly the ratio your riding demands without sourcing a different sprocket family.\u003c\/p\u003e\u003ch2\u003eFitment

generations — RJ11, RJ15 and RJ27 — the Sitta 201M aluminium rear sprocket delivers a precise, secure fit that makes installation straightforward and long-term reliability a given. Available in tooth counts from 37 to 48 and eight distinct finishes, it gives every R6 rider a single part that covers both gearing strategy and personal expression without compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFeatherlight aluminium construction tips the scales at just 350 g (size 45), reducing unsprung mass and sharpening throttle response without sacrificing rigidity.\u003c\/li\u003e\n\u003cli\u003e525-pitch teeth precisely machined for consistent chain engagement and minimised wear across both track sessions and high-mileage road use.\u003c\/li\u003e\n\u003cli\u003eSix-bolt carrier pattern 110\/130-6 ensures a flush, rattle-free mount on all compatible R6 rear hubs — no adapters, no fuss.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option outlasts standard anodising, resisting chain abrasion and road grime significantly longer for riders who demand maximum longevity.\u003c\/li\u003e\n\u003cli\u003eEight colour choices — silver, black, hard-anodised, red, blue, gold, orange and green — let you tailor the drivetrain's appearance to the rest of the build.\u003c\/li\u003e\n\u003cli\u003eBroad tooth range (37-48) covers everything from top-speed-oriented circuit gearing to short, aggressive street ratios in a single part number.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing Strategy Made Simple\u003c\/h2\u003e\u003cp\u003eSelecting the right rear sprocket tooth count has a direct and measurable effect on how your R6 feels at every point in the rev range. Understanding the trade-offs lets you choose once and ride with confidence.\u003c\/p\u003e\u003cp\u003eA smaller sprocket in the 37-42 tooth range raises the overall gearing, reducing engine revs at motorway speeds and unlocking a higher top speed on long straights — the preferred choice for circuits with sustained high-speed sections or touring-oriented road riders.\u003c\/p\u003e\u003cp\u003eStepping up to the 43-48 tooth range shortens the gearing, placing the R6's powerband to work earlier in each gear. The result is crisper acceleration out of slow corners, more responsive roll-on delivery and a more agile feel through technical sections — ideal for tight, twisty circuits or urban sport riding.\u003c\/p\u003e\u003ch2\u003eBuild Quality \u0026amp; Surface Finishes\u003c\/h2\u003e\u003cp\u003eThe 201M is cut from high-grade aluminium chosen for its combination of low mass and genuine structural integrity under sustained drivetrain load. The standard anodised finishes — silver, red, blue, gold, orange and green — provide a hard, corrosion-resistant surface layer that holds its colour well through the seasons. For riders operating in wet climates or running extended service intervals, the hard-anodised variant adds a measurably denser surface treatment that stands up to chain side-load and abrasive road contamination far better than conventional anodising.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is designed exclusively for the following models and is compatible only with 525-pitch chain:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R6 RJ11 (2003-2005)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R6 RJ15 (2006-2007)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R6 RJ27 (2008-2026)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCarrier bolt pattern: 110\/130 — 6-bolt.

Aluminium Rear Sprocket Suzuki GSX-R 1000 (2009-2023) – 525 Pitch, 37-48 Teeth (201M)","description":"\u003cp\u003eMachined from high-grade aluminium and finished to exacting tolerances, the Sitta 201M rear sprocket is engineered specifically for the Suzuki GSX-R 1000 in model years 2009 through 2023. Where stamped steel sprockets add unnecessary rotating mass, the 201M keeps weight to just 350 g at 45 teeth — a measurable advantage whether you are hunting lap times on track or extracting the most from spirited road riding.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePremium aluminium construction delivers a weight of only 350 g (at size 45), reducing unsprung and rotating mass for sharper throttle response and improved handling.\u003c\/li\u003e\n\u003cli\u003eEight anodised colour options — silver, black, hard-anodised, red, blue, orange, gold and green. The hard-anodised finish penetrates deeper into the alloy than standard anodising, providing superior abrasion resistance and a longer service life.\u003c\/li\u003e\n\u003cli\u003eTwelve tooth counts available — 37 through 48 — allowing precise gearing adjustment for track use, road touring or anything in between.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier pattern 110\/130-6 bolt ensures a precise, rattle-free fit and straightforward installation without modification.\u003c\/li\u003e\n\u003cli\u003eExclusively engineered for 525 pitch chains, maintaining optimal load distribution across each link for reduced wear on both sprocket and chain.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePrecision Build Quality\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 201M from a high-strength aluminium alloy that balances low mass with the rigidity required to handle sustained high-load power delivery. Each tooth profile is CNC-machined for consistent chain engagement and even wear distribution, extending service intervals beyond what a cast or stamped alternative can offer. The hard-anodised variant takes this further: the electrochemical treatment creates a surface hardness that outlasts conventional anodising, making it the preferred choice for track riders who cover high mileage between sprocket changes.\u003c\/p\u003e\u003ch2\u003eGearing Strategy\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count is one of the most cost-effective performance adjustments available for the GSX-R 1000. Fitting a smaller sprocket in the 37-42 teeth range shortens the overall gearing ratio, raising top speed and reducing engine revs on long straights or motorway runs. Moving to a larger sprocket in the 43-48 teeth range lengthens the ratio, sharpening acceleration out of corners and delivering more responsive throttle feel — the choice of track riders who prioritise drive over maximum speed. The 201M's twelve-count range means you can dial in exactly the ratio that suits your riding style without compromising fitment quality.\u003c\/p\u003e\u003ch2\u003eFitment and

craftsmanship and an eight-colour anodised finish range to give the Suzuki GSX-R 600 and GSX-R 750 rider a genuinely bespoke drivetrain upgrade. Whether the goal is shaving fractions off lap times or tuning the gearing for a long road season, the 201M delivers the substance to match its looks.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighing just 350 g at size 45 — reducing unsprung mass without sacrificing rigidity\u003c\/li\u003e\n\u003cli\u003eAvailable in eight distinct anodised finishes: silver, black, hard-anodised, blue, red, orange, gold and green — hard-anodised offering superior durability over standard anodising\u003c\/li\u003e\n\u003cli\u003eTwelve tooth counts from 37 to 48 teeth, letting you dial in acceleration bias or top-speed advantage to suit your riding style and circuit\u003c\/li\u003e\n\u003cli\u003eMachined exclusively for 525 pitch — optimised chain engagement for consistent power delivery and reduced wear\u003c\/li\u003e\n\u003cli\u003eSprocket carrier fitment: 110\/130-6 hole pattern for accurate, straightforward installation\u003c\/li\u003e\n\u003cli\u003eSuitable for both track and road use, resisting wear even under sustained high-load conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has been producing drivetrain components for competitive motorcycle use for decades, and the 201M rear sprocket reflects that pedigree. Every sprocket is CNC-machined from high-grade aluminium billet and finished with an anodised surface treatment that does more than look the part — it protects the tooth profile against corrosion and surface abrasion across seasons of hard use. The hard-anodised variant goes a step further, producing a surface hardness that measurably outlasts a conventional anodised finish, making it the preferred choice for riders who cover high mileage or compete regularly.\u003c\/p\u003e\u003cp\u003eThe colour palette — silver, black, hard-anodised, blue, red, orange, gold and green — gives every GSX-R owner the freedom to coordinate the sprocket with their machine's livery or simply choose the finish that appeals. This is not aftermarket cosmetics applied as an afterthought; the anodising is integral to the aluminium and will not peel or chip under normal operating conditions.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count is one of the most cost-effective ways to reshape how a motorcycle performs. On the GSX-R 600 and GSX-R 750, the 201M's range covers both ends of the spectrum.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket in the 37-to-42-tooth range produces a taller overall gearing ratio. The engine runs at lower revs at any given road speed, improving motorway composure and raising potential top speed — useful for fast, open circuits or extended road touring.\u003c\/p\u003e\u003cp\u003eA larger rear sprocket in the 43-to-48-tooth range shortens the gearing, sharpening throttle response out of slower corners and producing noticeably stronger acceleration through the lower gears. This is the preferred setup for technical tracks, hillclimbs or urban road riding where punch matters more than outright top speed.\u003c\/p\u003e\u003cp\u003eAt only 350 g for the size 45 example, the 201M is light enough that swapping sprockets between configurations adds a negligible weight penalty — a genuine advantage for riders who switch between road and track use.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is machined specifically for the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuzuki GSX-R 600 (2011-2016)\u003c\/li\u003e\n\u003cli\u003eSuzuki GSX-R 750 (2011-2016)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCompatible with 525 pitch chains only.

Aluminium Rear Sprocket for Marchesini, OZ and BST Carriers (201H) – 37-48 Teeth, 525 Pitch","description":"\u003cp\u003eEngineered for riders who refuse to compromise on fit, feel, or longevity, the Sitta 201H aluminium rear sprocket slots directly onto Marchesini, OZ and BST sprocket carriers with the precision you would expect from a purpose-built racing component. Available in 37 to 48 teeth for the 525 pitch chain, it lets you dial in exactly the gearing character your riding demands — whether that means effortless highway cruising or razor-sharp track acceleration.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighing just 350 g at size 45, reducing unsprung and rotating mass for sharper throttle response and more agile handling.\u003c\/li\u003e\n\u003cli\u003e12 tooth options from 37 to 48 teeth allow precise gearing tailored to your riding style, circuit layout or road preference.\u003c\/li\u003e\n\u003cli\u003eExclusive 525 pitch compatibility ensures optimum chain engagement, load distribution and drivetrain durability.\u003c\/li\u003e\n\u003cli\u003e76\/100-5 hole sprocket carrier pattern guarantees a secure, rattle-free fit on Marchesini, OZ and BST hubs with no modification required.\u003c\/li\u003e\n\u003cli\u003eEight anodised colour options — including hard-anodised finish which outlasts standard anodising under sustained stress and heat — let you match or contrast your wheel and chassis livery.\u003c\/li\u003e\n\u003cli\u003eHigh resistance to wear even under sustained high-load conditions, making it equally suited to track days and spirited road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGearing Guide: Choosing Your Tooth Count\u003c\/h2\u003e\u003cp\u003eSelecting the right tooth count transforms how your motorcycle feels on the road or circuit. Understanding the trade-offs helps you make the most of the 201H's wide range.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket (37–42 teeth) lowers the overall gearing ratio, reducing engine revs at a given road speed and extending your top speed potential — ideal for fast, flowing circuits or motorway commutes. A larger rear sprocket (43–48 teeth) raises the ratio, sharpening acceleration out of slow corners, improving low-speed traction feel and giving the bike a more responsive, agile character. The 201H covers both ends of the spectrum, so a single sprocket change is all it takes to remap your motorcycle's character for the day's task.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 201H from high-grade aluminium, struck to tight dimensional tolerances for consistent chain alignment and smooth power transfer. The standard anodised finishes — silver, black, orange, red, gold, green and blue — provide a clean protective layer that resists corrosion and minor abrasion. Riders who put heavy miles on track or in harsh conditions should consider the hard-anodised option, which delivers a substantially denser, harder surface than conventional anodising and significantly extends service life before visible wear appears.\u003c\/p\u003e\u003cp\u003eAt only 350 g for a 45-tooth sprocket, the weight saving over a steel equivalent is substantial. Lower unsprung mass directly benefits suspension compliance, and reduced rotational inertia means the engine spins up and responds to throttle inputs more freely — a genuine on-road and on-track advantage that you feel with every corner exit.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201H rear sprocket is designed exclusively for motorcycles equipped with Marchesini, OZ or BST wheels using the standard sprocket carrier interface. It is compatible only with 525 pitch chains and chains must be verified as 525 before ordering. The carrier bolt pattern is 76\/100-5 hole. Always verify your wheel brand, pitch, and carrier specification before purchasing.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart Number:

ride. The Sitta 207Y aluminium rear sprocket is precision-machined for the BMW S1000RR K67 (2019–2026), available in eleven tooth counts from 37 to 47 and eight anodised colours — giving you genuine gearing flexibility at an accessible price point, whether you use the bike daily or at the weekend.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrecision-machined aluminium construction delivers a strong power-to-weight ratio without excess cost\u003c\/li\u003e\n\u003cli\u003e525-pitch compatibility ensures direct fitment with standard and upgraded chain sets on the S1000RR K67\u003c\/li\u003e\n\u003cli\u003eEleven tooth options (37–47) let you tailor acceleration and top-speed characteristics to suit your exact riding style\u003c\/li\u003e\n\u003cli\u003eFive-bolt sprocket carrier interface (119 x 140 mm, 12.50 mm bolt hole) guarantees a precise, wobble-free fit\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option offers superior surface hardness and extended service life compared to standard anodising\u003c\/li\u003e\n\u003cli\u003eEight colour choices — silver, black, hard-anodised, red, blue, orange, gold and green — so the sprocket matches your bike's look\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Everyday Value\u003c\/h2\u003e\u003cp\u003eSitta manufactures the 207Y from quality aluminium chosen for its combination of light weight and resistance to the sustained loads a high-revving litre-class superbike generates. The tooth profile is cut to close tolerances so chain engagement stays clean from the first ride, reducing the uneven wear patterns that shorten chain life prematurely. For riders who cover a mix of commutes, touring and occasional track days, this is a sensible, cost-effective upgrade over OEM — easy to swap during a routine chain-and-sprocket service and available in enough colour options to suit any livery.\u003c\/p\u003e\u003ch2\u003eChoosing the Right Tooth Count\u003c\/h2\u003e\u003cp\u003eThe tooth count you select changes the effective gearing of your S1000RR in a predictable way, and with eleven options there is a meaningful choice for every use case.\u003c\/p\u003e\u003cp\u003eA smaller sprocket (37–42 teeth) raises overall gearing, reducing engine speed at motorway cruising pace and nudging the top speed ceiling higher — useful for extended road riding or long straights on track. A larger sprocket (43–47 teeth) shortens the gearing, sharpening throttle response out of slow corners and improving drive off the line, which suits tight, technical circuits or urban riding where acceleration matters more than outright speed. The stock tooth count is a sensible baseline; moving one or two teeth either side produces a noticeable but manageable change.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 207Y is designed and manufactured exclusively for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW S1000RR K67 — model years 2019 to 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThis sprocket is compatible with 525-pitch chains only.

Aluminium Rear Sprocket BMW M1000RR K66 (2021-2026) – 37-47T, 520 Pitch, Part 207Y","description":"\u003cp\u003eCrafted from aircraft-grade aluminium and available in eight distinctive anodised finishes, the Sitta 207Y rear sprocket is engineered specifically for the BMW M1000RR K66 — a machine that demands components as purposeful and refined as the chassis they serve. Whether you are chasing lap times or dialling in the perfect road setup, the 207Y gives you the precision, finish quality and heritage craftsmanship that Sitta has built its reputation on.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePremium aluminium construction delivers exceptional strength with minimal rotational mass — exactly what the high-revving M1000RR drivetrain deserves.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option provides significantly greater surface hardness and wear resistance than standard anodising, extending service life under sustained track use.\u003c\/li\u003e\n\u003cli\u003eEight colour options — silver, black, hard-anodised, red, blue, orange, gold and green — allow precise aesthetic matching to your BMW's livery or personal style.\u003c\/li\u003e\n\u003cli\u003eTooth range from 37 to 47 teeth lets you fine-tune gearing for your preferred circuit or riding discipline without changing the sprocket carrier.\u003c\/li\u003e\n\u003cli\u003e520-pitch specification pairs with performance chain kits for reduced weight and friction compared to heavier OEM-equivalent pitches.\u003c\/li\u003e\n\u003cli\u003ePrecise 5-bolt sprocket carrier interface (119 x 140 mm, 12.50 mm bolt holes) ensures a direct, play-free fit on the K66 carrier — no adaptation required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has been producing high-quality drivetrain components for road and race use for decades, and the 207Y reflects that accumulated engineering knowledge. Every sprocket is machined to tight tolerances, and the anodised surface treatments are applied to exacting standards — not as an afterthought, but as an integral part of the product's durability story.\u003c\/p\u003e\u003cp\u003eThe hard-anodised variant deserves particular attention. Where standard anodising adds colour and a modest degree of corrosion resistance, hard anodising penetrates deeper into the aluminium substrate, creating a surface layer that resists abrasion and chain wear far more effectively. For riders who cover high mileages or who regularly use their M1000RR on track, the hard-anodised 207Y is the intelligent long-term choice.\u003c\/p\u003e\u003cp\u003eFor those where visual impact is equally important, the full palette of colours — from understated silver to vivid orange and gold — means the 207Y can complement every specification of the M1000RR, from stock to fully race-prepared.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the right tooth count is one of the most cost-effective performance adjustments available to any M1000RR owner. The 207Y's 37-to-47-tooth range covers the full spectrum of road and track requirements.\u003c\/p\u003e\u003cp\u003eA smaller sprocket in the 37-to-42-tooth range shortens the overall gearing, raising top speed and reducing engine rpm at motorway cruising speeds — ideal for high-speed circuits or long touring stints. Moving to a larger sprocket in the 43-to-47-tooth range increases overall gearing, sharpening acceleration response and improving drive out of tight corners, which suits technical circuits and aggressive street riding alike.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 207Y is designed exclusively for the following

delivers a precise, rattle-free fit that inspires confidence whether you are carving through a Sunday morning road route or pushing hard on a track day.

Moving to a smaller sprocket in the 37-42 tooth range reduces the overall ratio, raising top speed and lowering engine revs at motorway cruise — ideal for fast circuit layouts or long-distance road riding. Stepping up to 43-47 teeth increases the ratio, sharpening acceleration out of slow corners and improving agility in technical sections. The Sitta 207Y sprocket gives you the freedom to swap between setups without investing in a new wheel carrier each time.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta machines the 207Y from high-grade aluminium to tolerances that ensure every tooth engages cleanly with the 525 chain link. The result is a drivetrain that transfers power efficiently and wears evenly across the full tooth profile. Standard anodised colours provide a durable, corrosion-resistant surface suited to road use in all conditions. The hard-anodised option goes further, creating an oxide layer with significantly greater hardness — the preferred choice for riders who log high mileage or compete regularly. All finishes are applied after machining so the dimensional accuracy of every sprocket remains unaffected.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 207Y rear sprocket is designed exclusively for the following model:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW M1000RR K66 — model years 2021 to 2026\u003c\/li\u003e\n\u003cli\u003e525 pitch chain only\u003c\/li\u003e\n\u003cli\u003eCarrier interface: 119 x 140 mm, 5-hole, 12.50 mm bolt holes\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlways verify your existing chain pitch before ordering.

Aluminium Rear Sprocket Yamaha YZF-R1\/M RN32\/RN49 \u0026 RN65 (2015-2026) 202M – 37-47 Teeth, 525 Pitch","description":"\u003cp\u003eFew components define the character of a Yamaha YZF-R1 or YZF-R1M like the rear sprocket, and the Sitta 202M has been shaped with that philosophy at its core. Machined from high-grade aluminium and finished in eight distinct anodised colours, this sprocket pairs racetrack-honed precision with a visual refinement that marks it out as something more than a simple replacement part — it is a deliberate upgrade for riders who care about every detail, from the first corner to the last straight.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHigh-grade aluminium construction delivers outstanding strength at genuinely reduced rotating mass, sharpening throttle response and agility on both road and track.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option outlasts standard anodising, resisting wear and corrosion even under sustained high-load conditions.\u003c\/li\u003e\n\u003cli\u003eEight colour options — silver, black, hard-anodised, blue, red, gold, green and orange — allow the sprocket to complement or contrast any livery.\u003c\/li\u003e\n\u003cli\u003eEleven tooth counts from 37 to 47 teeth let you fine-tune gearing precisely to your circuit or riding style, all in a single 525-pitch specification.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier dimensions of 112 mm x 138 mm with a 5-hole bolt pattern ensure a direct, play-free fit without adaptation.\u003c\/li\u003e\n\u003cli\u003ePrecise manufacturing tolerances mean straightforward installation and consistent chain alignment from the moment of fitting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eSitta has been producing drivetrain components for competition and road use for decades, and the 202M carries that heritage visibly. The anodising is applied after machining, locking colour into the metal surface rather than sitting on top of it, which is why the finish resists chipping and fading long after lesser sprockets have lost their appeal. The hard-anodised variant takes this further still, producing a surface hardness that bridges the gap between aluminium convenience and steel durability — the preferred choice for riders covering high mileages or running demanding track programmes.\u003c\/p\u003e\u003cp\u003eThe sculpted spoke design reduces material where it is not needed, and every colour variant is held to the same dimensional tolerances as the unfinished billet. Whether you select the understated silver or the more assertive gold or orange, you are receiving the same precision part underneath.\u003c\/p\u003e\u003ch2\u003eGearing and Performance\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count is one of the most cost-effective performance adjustments available on the YZF-R1 platform. A smaller rear sprocket in the 37-to-42-tooth range shortens the overall gearing ratio, raising top speed and reducing engine revolutions on long, open sections — ideal for high-speed circuits or motorway touring. Moving up to the 43-to-47-tooth range lengthens the ratio in the rider's favour, producing stronger acceleration out of tight corners and a more responsive throttle through technical sections. The 202M's eleven-step range means riders can dial in the exact characteristic they want without compromise.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta

Rear Sprocket for PVM Sprocket Carrier (201J) – 37-47 Teeth, 525 Pitch","description":"\u003cp\u003eGetting the most from a PVM sprocket carrier starts with a rear sprocket that is precision-made to match it — and the Sitta 201J delivers exactly that. Machined from lightweight aluminium, available in eleven tooth counts from 37 to 47, and offered in eight anodised colours, this is a practical, high-quality drivetrain component that works equally well on road and track without demanding a premium budget.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction keeps unsprung weight low — just 350 g in size 45 — improving handling response and reducing drivetrain stress.\u003c\/li\u003e\n\u003cli\u003eEleven tooth options (37 through 47) let you fine-tune your gearing to suit your riding style, your bike and the roads or circuits you frequent.\u003c\/li\u003e\n\u003cli\u003eDedicated 525 pitch ensures correct chain engagement and maximises sprocket longevity when paired with a matching 525 chain.\u003c\/li\u003e\n\u003cli\u003e80\/100 five-bolt carrier pattern fits PVM sprocket carriers precisely for a straightforward, play-free installation.\u003c\/li\u003e\n\u003cli\u003eHard-anodised finish option offers significantly greater surface hardness and wear resistance than standard anodising — ideal for riders who cover high mileage or run aggressive acceleration.\u003c\/li\u003e\n\u003cli\u003eEight colour choices — silver, black, hard-anodised, gold, red, blue, orange and green — so the sprocket can complement any livery rather than being an afterthought.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDialling In Your Gearing\u003c\/h2\u003e\u003cp\u003eChoosing the right tooth count is the single cheapest way to change how your motorcycle feels to ride. With the Sitta 201J spanning 37 to 47 teeth in one part number, you have real flexibility without needing to source from multiple suppliers.\u003c\/p\u003e\u003cp\u003eA smaller sprocket in the 37-42 tooth range shortens the overall gearing ratio, which reduces engine rpm at cruising speed and raises top speed — a useful tweak for motorway commuters or long-distance sport riders. Moving to the 43-47 tooth range lengthens the ratio, sharpening acceleration out of slow corners and making the bike feel more agile in technical sections. Either way, the part number remains 201J and the installation process is identical.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Everyday Reliability\u003c\/h2\u003e\u003cp\u003eSitta machines the 201J from quality aluminium chosen for its strength-to-weight ratio. The tooth profile is cut to maintain consistent engagement across the full service life of the sprocket. The hard-anodised variant goes a step further: the electrochemical process penetrates the surface of the aluminium rather than simply coating it, producing a finish that resists wear, corrosion and chain abrasion far better than conventional anodising. For riders who want a longer service interval without moving to a heavier steel sprocket, hard-anodised is the sensible choice.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis sprocket is designed exclusively for motorcycles equipped with a PVM sprocket carrier using the 80\/100 five-bolt pattern.

A smaller sprocket in the 37-to-42 tooth range lowers overall gearing, which reduces engine rpm at motorway speeds and extends the top end — useful for circuits with long straights or for relaxed road touring. Moving to the 43-to-47 tooth range raises the gearing ratio, sharpening initial acceleration and making the bike feel more responsive through tight sections. The Sitta 204Y range lets you make that adjustment without changing your sprocket carrier or chain pitch.\u003c\/p\u003e\u003ch2\u003eBuild Quality \u0026amp; Finish\u003c\/h2\u003e\u003cp\u003eSitta machines the 204Y from high-grade aluminium, balancing the need for low mass with genuine structural integrity. The standard anodised finishes — silver, black, red, blue, gold, orange and green — provide good corrosion resistance and a clean appearance that holds up well in road use. The hard-anodised option goes further, producing a surface layer that is significantly harder and more abrasion-resistant, making it the sensible choice if the bike sees heavy track use or high-mileage road riding where chain wear is a constant concern.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 204Y is designed exclusively for BMW models fitted with the HP Schmiederad (HP Forged Wheel).

confidence-inspiring combination of low unsprung weight, dependable power transfer and all-day riding comfort on the BMW S1000RR K46.

Understanding the trade-off lets you build a drivetrain that genuinely suits how you ride.\u003c\/p\u003e\u003cp\u003eA smaller rear sprocket (37 to 42 teeth) lowers engine revs at any given road speed, easing the workload on long runs and nudging the bike's character towards a more relaxed, mile-eating feel without blunting outright performance. A larger rear sprocket (43 to 47 teeth) shortens the overall gearing ratio, sharpening initial acceleration out of corners and giving the bike a more aggressive, responsive feel — the preferred choice for track days and technical roads where momentum changes are constant.\u003c\/p\u003e\u003cp\u003eWith eleven tooth counts available in the Sitta 202Y range, you can step the gearing in single-tooth increments until the bike responds exactly as you want it to, without any compromise on fitment or chain alignment.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Durability\u003c\/h2\u003e\u003cp\u003eSitta machines the 202Y from aerospace-grade aluminium alloy, achieving the strength-to-weight ratio that performance riders demand. The anodised surface treatments — particularly the hard-anodised option — add a dense oxide layer that resists the abrasion generated by chain side-loads and the grit thrown up during real-world riding. The result is a sprocket that maintains its tooth profile and carrier register far longer than cheaper alternatives, protecting your chain investment at the same time.\u003c\/p\u003e\u003cp\u003eThe 5-bolt carrier interface distributes load evenly around the full hub diameter, eliminating the stress concentrations that contribute to premature carrier wear. Every hole is machined to close tolerances so that fitting is straightforward and torquing the bolts to specification produces the same feel every time — no oval holes, no rework required.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 202Y rear sprocket is designed exclusively for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW S1000RR K46 — model years 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 and 2018\u003c\/li\u003e\n\u003cli\u003eCompatible with 525 pitch chain only\u003c\/li\u003e\n\u003cli\u003eCarrier bolt pattern: 110 mm x 131 mm, 5-hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAlways verify your existing chain pitch before ordering.

Aluminium Rear Sprocket Kawasaki ZX-10R\/RR Ninja (2004-2026) 201W – 37-47 Teeth, 525 Pitch","description":"\u003cp\u003ePrecision-engineered in premium aluminium and offered in eight distinctive finishes, the Sitta 201W rear sprocket brings genuine German manufacturing heritage to the drivetrain of the Kawasaki ZX-10R and ZX-10RR Ninja.

The colour range is far wider than most aftermarket alternatives — not merely a cosmetic gesture, but a reflection of Sitta's commitment to precision anodising processes that are integral to the part's surface hardness and corrosion resistance. The hard-anodised variant in particular undergoes a more intensive electrochemical treatment, producing a surface that outlasts conventionally anodised aluminium under the heat and abrasion cycles typical of track use. Whichever colour you select, the finish is uniform and deep, not a thin coat applied after the fact.\u003c\/p\u003e\u003cp\u003eThe machined tooth profile is consistent across the full range of tooth counts, maintaining the same engagement geometry whether you run a 37-tooth setup for maximum top speed or push to 47 teeth for sharper corner-exit drive. This consistency is characteristic of a manufacturer that tools every variant from the same design philosophy rather than treating fringe sizes as afterthoughts.\u003c\/p\u003e\u003ch2\u003eUnderstanding Gearing Choice on the ZX-10R\u003c\/h2\u003e\u003cp\u003eSelecting the correct tooth count fundamentally changes the character of the ZX-10R's power delivery. A smaller rear sprocket in the 37-to-42 tooth range lowers overall gearing, raising top speed and reducing engine revs at motorway speeds — ideal for long circuit straights or fast road riding. Moving to the 43-to-47 tooth range raises overall gearing, sharpening acceleration out of slow corners and making the bike feel more responsive in traffic or on tight technical circuits. The 201W's breadth of choice means a single part number covers every realistic scenario for this platform without compromise.\u003c\/p\u003e\u003ch2\u003eFitment and

a trackday — the Sitta 201W is machined from quality aluminium to give your Kawasaki ZX-6R, ZX-636 or ZX-6RR a lighter drivetrain without sacrificing durability.

Each sprocket is machined to close tolerances so that chain engagement is even across all teeth, reducing localised wear and extending service intervals. The hard-anodised colour option goes through an electrochemical process that converts the surface layer into a dense aluminium oxide, producing a finish that outlasts conventional anodising under repeated chain contact. The remaining seven colours are standard anodised, offering a clean, corrosion-resistant appearance that holds up well in road conditions.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201W is designed exclusively for the following models:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKawasaki ZX-6R \/ ZX-636 \/ ZX-6RR (2007-2026)\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThis sprocket is compatible with 525 pitch chain only.

Sitta 201W aluminium rear sprocket is purpose-built for the Kawasaki ZX-6R, ZX-636, and ZX-6RR (2007–2026).

The hard-anodised finish option is particularly notable: the hard-anodising process penetrates deeper into the aluminium surface than standard anodising, producing a significantly harder outer layer that resists abrasion and corrosion far more effectively during prolonged use. The remaining seven colour finishes — black, silver, orange, blue, gold, red, and green — are standard anodised and offer a clean, durable appearance suited to road and occasional track use.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201W rear sprocket is compatible with the following models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eKawasaki ZX-6R Ninja — model years 2007 to 2026\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-636 Ninja — model years 2007 to 2026\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-6RR Ninja — model years 2007 to 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSprocket carrier specification: 80\/104-6 hole pattern.
