DescriptionThe whole story▼
When every tenth of a second matters at the track, rotating mass is the enemy. The Sitta 202P aluminium rear sprocket for the Aprilia RS 660 (2020-2026) addresses that directly — tipping the scales at just 350 g in size 45, it trims unsprung and rotating weight simultaneously, sharpening throttle response and acceleration in a way no engine tune alone can match.
Key Features
- Lightweight aluminium construction weighing just 350 g (size 45), reducing rotating mass for faster acceleration and more responsive handling on track and road alike.
- Wide tooth range from 37 to 48 teeth in 520 pitch, letting you fine-tune gearing for specific circuits, sprint stages or your preferred road riding style.
- High-grade aluminium alloy with corrosion resistance built in, ensuring lasting reliability even under the heat cycles and mechanical stress of repeated track sessions.
- Eight colour options including hard-anodised finish — more durable than standard anodising — plus silver, black, red, blue, gold, orange and green to match or contrast your RS 660's livery.
- 100/120-5 hole sprocket carrier pattern for a direct, secure fit with no modification required.
- Precision CNC manufacturing to tight tolerances, guaranteeing consistent chain engagement and predictable power delivery lap after lap.
Built for the RS 660 Rider Who Pushes Limits
The Aprilia RS 660 is one of the most track-ready middleweights available, and the Sitta 202P is engineered to complement that intent. Reducing rotating inertia at the rear wheel means the engine's power translates more directly into forward motion — you feel the difference most acutely when rolling on out of slow corners or during rapid gear changes. The precision tooth profile keeps the 520 chain seated cleanly under hard acceleration and aggressive engine braking, minimising drivetrain snatch and extending chain life at the same time.
Gearing Flexibility for Every Application
Choosing the right rear sprocket tooth count is one of the simplest and most cost-effective performance adjustments available. Fitting a larger sprocket increases acceleration and bottom-end pull — ideal for tight, technical circuits. A smaller count raises top speed and relaxes engine revs at motorway speeds. With 12 tooth options spanning 37 to 48, the Sitta 202P covers every realistic use case for the RS 660, from trackday sprint to long-distance road riding. Pairing it with a front sprocket change extends the range of ratios even further.
Finish & Colour Options
All eight finishes are available across the full tooth range. The hard-anodised option offers superior surface hardness compared to conventional anodising, making it the preferred choice for riders who complete regular track days and want a sprocket that keeps its appearance under sustained use. The remaining colours — silver, black, red, blue, gold, orange and green — are standard anodised and give plenty of scope to coordinate with the RS 660's bodywork or wheel colour.
