Description
A smaller front sprocket delivers quicker acceleration and sharper throttle response—essential upgrades for trail riding and competitive ATV racing where weight and responsiveness directly impact lap times. The Renthal 14-tooth combines aggressive gearing with robust materials and self-cleaning geometry, ensuring reliable power delivery even in demanding conditions where chain wear and debris are constant threats.
Built from case-hardened 655M13 nickel-chromium steel, this sprocket resists the tooth wear and fatigue that plague standard components. The self-cleaning mud grooves actively shed dirt and mud during rotation, maintaining consistent engagement with your 520 chain and extending overall drivetrain life. You’ll notice the weight savings immediately—roughly 10-15% lighter than OEM equivalents—which compounds acceleration gains and improves chassis handling without requiring any other modifications.
Installation is straightforward: this is a bolt-on replacement requiring no fabrication or special tools beyond basic mechanical competency.
