Description
Yamaha off-road and motocross bikes chew through rear sprockets faster than most riders expect, especially once mud, sand, or dust gets packed between the teeth. ProTaper answered that problem with the Race Spec Rear Black Sprocket, and this listing is the 48-tooth version built for the Yamaha 46-49 tooth platform. Instead of a conventional flat groove, ProTaper angled the mud channel across the sprocket face so debris is thrown outward as the wheel spins, rather than sitting in the teeth and grinding away at your chain.
Features and Benefits
- Angled Mud Groove sheds mud and roost during operation instead of trapping it against the chain
- Increases tooth surface contact area by as much as 40% versus standard competitor sprockets
- Improved chain-to-tooth contact translates into noticeably longer sprocket service life
- Countersunk bolt holes self-center the sprocket on the hub, eliminating the need for a separate center guide
- Precision CNC machining keeps tooth spacing consistent for smoother chain engagement
- 48-tooth gearing option within the Yamaha 46-49T rear sprocket family
This sprocket bolts straight to stock Yamaha rear hub patterns covered in the 46-49T range, no modification needed. A 48T rear is a common step up for riders who want a bit more acceleration and torque multiplication without going too far into the lower gearing range. Run it with a properly tensioned, well-lubed chain for maximum life, and expect it to hold up in the kind of muddy, sandy conditions that destroy budget sprockets. IPD Racing carries this as a genuine ProTaper part, shipped from stock and backed by the manufacturer warranty.
