DescriptionThe whole story▼
When lap times matter, every link in the drivetrain counts. The Sitta M005 front sprocket is machined from high-tensile chrome-molybdenum steel and engineered to deliver precise, consistent power transfer on the Yamaha R3 across its full 2015-2026 model range — whether you are chasing a personal best on circuit or pushing hard on a favourite road.
Key Features
- Chrome-molybdenum steel construction for exceptional strength and resistance to wear under sustained high-rpm conditions
- Six tooth options — 13, 14, 15, 16, 17 and 18 teeth — allowing you to dial in exactly the gearing ratio your riding demands
- 520 pitch compatibility, matching the standard Yamaha R3 chain specification without requiring a chain conversion
- Precision-machined profile ensures zero play on installation and smooth, rattle-free engagement throughout the chain's service life
- Shorter gearing (13 or 14 teeth) sharpens throttle response and acceleration out of tight corners; longer gearing (17 or 18 teeth) raises top speed and lowers engine revs on extended straights
- Motorsport-grade quality equally at home on track days and daily road use
Choosing Your Gearing Ratio
The front sprocket is one of the quickest and most cost-effective ways to transform how your R3 feels to ride. Dropping to 13 or 14 teeth shortens the overall gearing, delivering noticeably sharper acceleration and a more agile throttle response — the natural choice for tight, technical circuits. Moving up to 17 or 18 teeth lengthens the ratio, reducing engine revs at motorway speeds and extending the top-end pull on long straights or open roads. The six available sizes mean you can experiment and find the exact balance between acceleration and top speed that suits your style and circuit.
Build Quality
Sitta manufactures the M005 from chrome-molybdenum steel — a material chosen specifically for its combination of high tensile strength and toughness. This alloy resists the surface fatigue and stretching that progressively degrade standard sprockets, keeping chain wear to a minimum and maintaining accurate engagement across the full service interval. The result is a drivetrain that feels tight and responsive for longer, reducing the frequency and cost of chain-and-sprocket replacements.
Please note: the product image currently displayed shows the sprocket for the Yamaha R6. The Sitta M005 for the Yamaha R3 is very similar in appearance.
