DescriptionThe whole story▼
Keeping your BMW S1000RR K67 running smoothly day after day demands drivetrain components that genuinely earn their place. The Sitta 207Y aluminium rear sprocket delivers reliable power transfer, precise fitment and a wide range of tooth counts — making it equally at home on your morning commute or a weekend blast, without asking you to spend race-team money.
Key Features
- Machined from quality aluminium for a practical balance of low weight and everyday durability
- 520 pitch compatible — suits the popular conversion standard for the S1000RR K67 platform
- Eleven tooth options from 37 to 47 teeth let you tailor gearing to suit your riding style and route
- Sprocket carrier dimensions of 119 x 140 mm, 5-hole pattern, bolt hole 12.50 mm ensure a precise, rattle-free fit
- Hard-anodised finish option offers superior wear resistance compared to standard anodising, extending service life under repeated stress
- Available in eight colours — silver, black, hard-anodised, red, blue, orange, gold and green — so the look matches your bike without a premium
Built for Reliable Everyday Use
The 207Y is manufactured to consistent tolerances, which means installation is straightforward and the sprocket seats correctly against the carrier without the need for adjustment. The aluminium construction keeps unsprung weight in check, which helps the suspension do its job more effectively whether you are filtering through city traffic or carrying speed through a sweeping A-road.
The hard-anodised colour variant deserves a mention for riders who cover serious mileage. The harder surface layer resists chain wear noticeably longer than conventional anodising, so you spend less time in the garage and more time riding. The remaining seven colour options use a quality standard anodised or dye finish that holds up well under normal road conditions.
Understanding Gearing — Choosing the Right Tooth Count
Selecting the correct rear sprocket tooth count changes the character of your S1000RR in a meaningful way, and the 207Y range makes experimenting affordable.
- Smaller sprockets (37–42 teeth): lower overall gearing raises top speed and reduces engine revs at motorway cruising speeds — ideal for long touring stints or track circuits with extended straights
- Larger sprockets (43–47 teeth): higher overall gearing improves acceleration response and makes the bike feel more agile out of slow corners — suited to technical roads and shorter circuits
Because the 207Y is available across eleven sizes, you can make a single tooth change at a time to find exactly the ratio that suits your style, rather than committing to a large jump.
Fitment and Compatibility
This sprocket is engineered specifically for the BMW S1000RR K67 produced between 2019 and 2026. It is compatible with 520 pitch chains only. Always verify your chain pitch before ordering if you are unsure whether your bike has already been converted from the standard 525 pitch.
