Description
If you’re running a 428 chain on your off-road bike, sprocket wear directly impacts acceleration response and chain longevity. Renthal’s 14-tooth front sprocket cuts rotational mass while the self-cleaning mud grooves eliminate the power loss and premature wear that comes from packed debris. Built from case-hardened 655M13 nickel-chromium steel, this is precision engineering that translates to measurable performance gains on the track or trail.
The ultralight construction delivers a 10-15% weight reduction at the rotating assembly—a critical advantage for snap throttle response and reduced unsprung mass. CNC-machined to tight tolerances, this sprocket maintains consistent chain engagement lap after lap, even under the harshest conditions.
