Description
A rear sprocket takes more abuse than almost any other drivetrain part on a Yamaha off-roader, and the ProTaper Race Spec Rear Black Sprocket in a 47-tooth count was built specifically to survive that punishment. The signature Angled Mud Groove is cut into the sprocket face at a precise angle rather than a straight line, so packed mud and roost get flung clear instead of building up between the teeth and the chain. That self-cleaning behavior matters most exactly when you need it: mid-moto, in the whoops, when a clogged sprocket would otherwise start eating horsepower and chewing up your chain.
Features and Benefits
- Angled Mud Groove design creates a self-cleaning effect during operation, shedding mud instead of trapping it
- CNC-machined tooth profile increases usable tooth surface area by up to 40% over competing sprockets
- Larger contact area improves chain engagement and slows sprocket wear over time
- Self-centering countersinks align the sprocket to the hub automatically, so no hub center guide tool is needed at install
- Black anodized finish resists corrosion from mud, water, and trail grime
- 47-tooth count for Yamaha applications running the Rear Sprockets – Yamaha 46-49 Tooth range
Bolt this on with your existing Yamaha rear hub and stock hardware; the countersink geometry does the centering work for you, so installation is a straightforward wheel-off job. Riders running this 47T option are typically dialing in gearing for tighter, technical terrain where quick acceleration out of corners matters more than top-end pull. Pair it with a fresh chain for the best results, and expect the kind of consistent, mud-shedding performance that has made ProTaper a go-to sprocket brand in the pits. IPD Racing stocks this part number ready to ship, genuine ProTaper, backed by the manufacturer.
