Description
A worn-out rear sprocket will chew up a fresh chain in a hurry, and ProTaper designed the CS4 Rear Steel Sprocket specifically to stop that cycle before it starts. This particular unit is the 36-tooth version, machined to fit Yamaha YFM250, YFM350, YFM700, and YFZ450 (2004 and up). Because this sprocket keeps its tooth profile true longer than a stock unit, chain slap and drivetrain lash both stay more consistent as the miles add up.
Features and Benefits
- Diamond-Cut tooth profile is roughly 25% harder than a standard-cut tooth for longer service life
- Exclusive KTL coating resists corrosion and holds a durable finish through repeated mud and water exposure
- Machined from high-strength 460 steel for consistent tooth geometry under load
- Built for reliable, consistent power delivery in off-road and motocross conditions
- 36-tooth count sized for Yamaha YFM250, YFM350, YFM700, and YFZ450 (2004 and up)
- Direct bolt-on replacement using the stock hub bolt pattern
Direct-fit for Yamaha YFM250, YFM350, YFM700, and YFZ450 (2004 and up), this sprocket keeps the stock bolt pattern so installation is straightforward. Pair it with fresh chain and sprocket lube for the best return on the harder tooth surface. IPD Racing stocks this genuine ProTaper part, backed by the manufacturer.
