The Sitta 201M is a precision-machined aluminium rear sprocket purpose-built for the R7 (2021–2026), available in twelve tooth counts from 37 to 48 and eight anodised finishes, so you get exactly the gearing and look your bike needs without compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLightweight aluminium construction weighing just 350 g (at size 45), keeping unsprung mass low for sharper handling and reduced drivetrain strain.\u003c\/li\u003e\n\u003cli\u003eTwelve tooth count options from 37 to 48 teeth let you dial in gearing for everything from relaxed road touring to aggressive track sessions.\u003c\/li\u003e\n\u003cli\u003eOptimised for 520 pitch chains — the standard fitment for performance-focused R7 builds and direct replacements.\u003c\/li\u003e\n\u003cli\u003eSprocket carrier pattern 110\/130 – 5-hole for a precise, rattle-free fit and straightforward installation without modification.\u003c\/li\u003e\n\u003cli\u003eEight colour options including hard-anodised finish — more durable than standard anodising — alongside silver, black, red, blue, gold, orange and green.\u003c\/li\u003e\n\u003cli\u003ePart number 201M guarantees you are ordering the exact Sitta specification for this fitment.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eChoosing the Right Tooth Count for Your Riding\u003c\/h2\u003e\u003cp\u003eThe 201M covers a wide enough range that you can meaningfully change how the R7 behaves day to day. A smaller rear sprocket (37–42 teeth) lowers the overall gearing ratio, which translates to a higher top speed and lower engine revs at motorway speeds — ideal if most of your riding is open-road touring or you commute regularly and want the engine to breathe more easily at a cruise.\u003c\/p\u003e\u003cp\u003eMoving up to a larger sprocket (43–48 teeth) tightens the gearing and improves acceleration, making the R7 feel more responsive out of slow corners and in stop-start urban conditions. Track riders often run 45 or 46 teeth for more precise corner exit drive, while riders who want a livelier, more engaging feel on B-roads also benefit from the extra low-speed punch without needing any engine modifications.\u003c\/p\u003e\u003ch2\u003eBuild Quality and Finish\u003c\/h2\u003e\u003cp\u003eSitta manufacture the 201M from high-grade aluminium — a material chosen for its combination of strength, machinability and low weight rather than cost alone. The tooth profile is CNC-machined to tight tolerances so chain engagement is smooth and consistent, which reduces chain and sprocket wear over time and extends the service life of the whole drivetrain. The hard-anodised option provides a surface treatment that is considerably harder and more abrasion-resistant than conventional anodising, making it the sensible choice for riders who cover high mileage or want the longest possible service interval between sprocket changes.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Sitta 201M rear sprocket is
