Description
Rotational mass directly impacts throttle response and handling—every gram counts on the track or trail. The Renthal 41-Tooth Ultralight Rear Sprocket cuts weight by 66% compared to steel while maintaining the strength needed for hard acceleration and sustained performance. If you’re serious about reducing unsprung weight and improving your Yamaha’s responsiveness, this is the upgrade that delivers measurable results.
CNC-machined from 7075-T6 aluminum alloy, this sprocket combines aerospace-grade material science with precision engineering. The self-cleaning mud grooves prevent debris accumulation, keeping your drivetrain operating at peak efficiency in demanding conditions. Direct bolt-on fitment means installation is straightforward—no fabrication required.
