VORTEX Steel Rear Sprocket - 42 Tooth - Honda 251AS-42

A worn or mismatched rear sprocket directly impacts your bike's acceleration, top-end speed, and overall drivability. The VORTEX 42-tooth rear sprocket is engineered for riders who demand consistent power delivery and longevity under demanding conditions. Whether you're chasing lap times or putting miles on your daily rider, a quality sprocket ensures your power gets to the ground efficiently without premature wear.

This sprocket is constructed from hardened carbon steel with a corrosion-resistant satin black electroplate finish—meaning it performs in wet conditions without sacrificing durability. The cupped tooth design reduces rotational mass while maintaining full strength, translating to quicker throttle response and less strain on your drivetrain.
