Description
A worn sprocket puts more load on the chain than most riders realize, shortening the life of both parts at the same time. ProTaper built its Race Spec (RS) rear sprockets around a CNC-machined Angled Mud Groove that channels debris away from the tooth roots as the wheel spins, instead of letting it pack in and wear a groove into the chain. This red 48-tooth rear sprocket is machined for Honda off-road models, and the groove layout also opens up roughly 40 percent more tooth surface area than a standard flat-plate design, so the chain rides on more material with every link that engages.
What makes this sprocket worth the swap:
- Angled Mud Groove design self-cleans during operation, shedding packed mud and dirt instead of trapping it against the chain
- CNC-machined tooth profile increases contact surface area versus flat competitor designs, which spreads load and slows wear
- Countersunk bolt holes self-center the sprocket onto the hub during installation, so no separate hub center guide tool is needed
- 48-tooth count for Honda off-road models, sold individually and ready to bolt on with stock hardware
- The red anodized finish plays well with Honda red plastics and holds its color under UV and grime longer than a painted sprocket would.
Running a 48T rear tightens acceleration through each gear, useful for tracks with tighter turns or riders who want the bike to snap up out of ruts instead of lugging. Whether this replaces a worn factory sprocket or sets up a new gear ratio for your track, it mounts with the tools already in your garage.
