Sitta Aluminium Rear Sprocket Suzuki GSX-R 600 & 750 (2003-2010) – 520 Pitch, 37-47 Teeth (201Z)

Crafted 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.

Key Features

• High-grade aluminium construction keeps weight to just 350 g (size 45), reducing unsprung mass for sharper throttle response and improved agility.
• 520 pitch optimised for performance and racing applications — lighter and faster than the stock 530 conversion.
• Eleven tooth options from 37 to 47 teeth let you dial in the exact gearing ratio for your riding style, circuit or road conditions.
• Hard-anodised finish option offers superior surface hardness and wear resistance compared to standard anodising — ideal for high-mileage or track use.
• Available in multiple colours — hard-anodised, black, silver, blue, red, green, orange and gold — so your drivetrain reflects your build's character.
• Sprocket carrier dimensions of 120 x 140 mm, 5-bolt pattern, 10.50 mm bolt holes ensure precise, straightforward fitment with no modification required.

Design, Finish and Heritage

Sitta 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.

Gearing Strategy

Choosing 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.

Fitment & Compatibility

The Sitta 201Z rear sprocket is designed exclusively for the following models and is compatible with 520 pitch chains only:

• Suzuki GSX-R 600 (model years 2003–2010)
• Suzuki GSX-R 750 (model years 2003–2010)

Sprocket carrier interface: 120 x 140 mm, 5-bolt pattern, bolt hole diameter 10.50 mm. Always verify your chain pitch before ordering — if your bike is running the original 530 chain, a full 520 conversion kit is required.
