Supersprox 13-Tooth Countershaft Sprocket (CST-250-13-1)

Upgrade your motorcycle’s drivetrain with the Supersprox CST-250-13-1 13-Tooth Countershaft Sprocket, engineered for dependable performance in off-road and street applications. Manufactured from SCM-435 carbon-free steel, this countershaft sprocket is designed to withstand demanding riding conditions while helping support extended sprocket and chain life. Its factory team specification reflects the performance standards used by professional racing teams.
The sprocket features a specially hardened surface layer that helps reduce friction between the chain and teeth. By minimizing chain drag, the Supersprox CST-250-13-1 can help reduce power loss and deliver smooth, efficient power transfer through the drivetrain. The hardened surface also provides added durability in high-use environments, making it a practical choice for riders who require consistent performance from their motorcycle’s final drive system.
A fully lightened construction with radial holes helps reduce unnecessary rotating weight without compromising the sprocket’s functional strength. Grooved teeth are modeled after Supersprox factory racing components and help clear dirt and debris quickly during off-road riding. This design supports reliable chain engagement in muddy, dusty, and abrasive conditions while also remaining suitable for street use.
