DescriptionThe whole story▼
Machined 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.
Key Features
- Premium aluminium construction delivers a weight of only 350 g (at size 45), reducing unsprung and rotating mass for sharper throttle response and improved handling.
- Eight 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.
- Twelve tooth counts available — 37 through 48 — allowing precise gearing adjustment for track use, road touring or anything in between.
- Sprocket carrier pattern 110/130-6 bolt ensures a precise, rattle-free fit and straightforward installation without modification.
- Exclusively engineered for 525 pitch chains, maintaining optimal load distribution across each link for reduced wear on both sprocket and chain.
Precision Build Quality
Sitta 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.
Gearing Strategy
Selecting 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.
Fitment and Compatibility
This sprocket is designed and validated for the following application:
- Suzuki GSX-R 1000 — model years 2009 to 2023
- 525 pitch chain only — not compatible with 520 or 530 pitch chains
- Sprocket carrier: 110/130-6 bolt pattern
- Part number: 201M
