Description
Quad and ATV riders pushing a 02-08 Kaw KX250/11-23 Yam YZ250X/WR450F/01-05 660 Raptor through mud and sand know the front sprocket is one of the first drivetrain parts to show its age. Renthal cuts the tooth profile from hardened steel and holds tight bore tolerances, keeping the chain tracking straight even as mud and grit work into the drivetrain.
That matters most on long trail rides or a full moto in the sand, when a rounded tooth starts letting the chain ride up instead of driving it cleanly. Key features:
- 13-tooth count, 520 pitch, matched to the stock final drive ratio on the 02-08 Kaw KX250/11-23 Yam YZ250X/WR450F/01-05 660 Raptor
- Self-cleaning mud grooves machined into the tooth profile help shed dirt and debris so the chain keeps full contact instead of riding up on packed mud
- CNC-machined for a true, concentric bore so the sprocket runs straight on the output shaft instead of introducing chain slap
- Hardened steel construction built to hold a square tooth profile longer than a soft stamped factory sprocket
- Genuine Renthal part, the same brand used across professional motocross, enduro, and road racing paddocks
- Suited to trail riding, racing, and mud where a front sprocket wears unevenly under constant load changes
This part fits the 02-08 Kaw KX250/11-23 Yam YZ250X/WR450F/01-05 660 Raptor in 520 pitch, 13-tooth count, straight off the stock output shaft with no adapter required.
