Sitta Aluminium Rear Sprocket for Suzuki GSX-R 600 & 750 (2011-2016) – 37-48 Teeth, 520 Pitch (201M)

Crafted from precision-machined aluminium and offered in eight distinctive anodised finishes, the Sitta 201M rear sprocket is where considered engineering meets real aesthetic intent. Designed specifically for the Suzuki GSX-R 600 and GSX-R 750 from 2011 to 2016, this sprocket brings Sitta's long-standing drivetrain heritage to one of the most celebrated middleweight supersports ever built.

Key Features

• Ultralight aluminium construction weighing just 350 g at size 45, reducing unsprung and rotating mass for sharper throttle response
• Available in 37 to 48 teeth across 520 pitch, giving you complete control over your final drive ratio for both track and road use
• Eight anodised colour options — silver, black, hard-anodised, blue, red, orange, gold and green — each a genuine finish, not a coating
• Hard-anodised variant offers superior surface hardness and wear resistance compared to standard anodising, extending sprocket life under sustained high loads
• 110/130 6-bolt sprocket carrier fitment ensures accurate alignment and straightforward installation without modification
• Precision CNC machining guarantees consistent tooth profile for smooth, efficient power transfer and reduced chain wear

Design, Finish and Heritage

Sitta has been manufacturing drivetrain components for performance motorcycles for decades, and the 201M reflects that accumulated knowledge in every detail. 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.

The 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.

Gearing Strategy: Choosing Your Tooth Count

The 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.

Fitment & Compatibility

The Sitta 201M is engineered exclusively for the following models and is compatible with 520 pitch chains only:

• Suzuki GSX-R 600 (2011 – 2016)
• Suzuki GSX-R 750 (2011 – 2016)

Sprocket carrier: 110/130 — 6-bolt pattern. Always verify your current sprocket carrier specification before ordering, and ensure your chain is 520 pitch or convert your drive accordingly.
