Renthal 337-520-12GP Grooved Front Sprocket, 12-Tooth for Kawasaki (337--520-12GP)

Upgrade your Kawasaki motorcycle’s drivetrain with the Renthal 337-520-12GP Grooved Front Sprocket. Designed for demanding off-road and performance applications, this 12-tooth front sprocket is CNC-machined from case-hardened and core-refined 655M13 nickel-chromium steel for dependable strength, precise fitment, and long-term wear resistance. The Renthal engineering process delivers a durable replacement component built to withstand the stress of serious riding.
Self-cleaning mud grooves are machined into each tooth to help prevent mud and debris from accumulating between the sprocket and chain. By reducing buildup, the grooved tooth design helps maintain smooth chain engagement and supports consistent drivetrain performance in muddy, wet, and abrasive riding conditions. This feature also helps increase wear resistance compared with conventional sprocket designs.
The Renthal 337-520-12GP uses an ultralight construction that provides a 10-15% weight savings while maintaining the strength required for off-road use. Reduced rotating weight can contribute to responsive handling and efficient power transfer, making this front sprocket a practical choice for riders seeking performance-focused drivetrain upgrades. Confirm motorcycle application and chain compatibility before installation.
