Supersprox 16-Tooth Countershaft Sprocket (CST-546-16-1)

Upgrade your motorcycle’s drivetrain with the SUPERSPROX CST-546-16-1 16-tooth countershaft sprocket, engineered for demanding off-road and street applications. Manufactured from SCM-435 carbon-free steel, this sprocket is designed to provide dependable strength, consistent performance, and extended sprocket life. Its construction is impregnated to help minimize the risk of breakage under demanding riding conditions, making it a reliable choice for riders seeking race-inspired drivetrain components.
The ultra-hard surface layer measures approximately 0.02 inches thick and helps reduce friction between the sprocket and chain. By minimizing chain drag, the SUPERSPROX countershaft sprocket helps limit unnecessary power loss and supports efficient power transfer to the rear wheel. The sprocket is fully lightened with radial holes, reducing unnecessary weight while maintaining the durability required for aggressive riding and varied terrain.
Grooved teeth are designed specifically for off-road use, helping dirt and debris clear quickly from the tooth profile during operation. This feature is modeled after factory racing components and supports smoother chain engagement in muddy, dusty, or gritty conditions. The 16-tooth configuration provides a balanced fitment option for riders tuning final-drive performance, acceleration, and cruising characteristics.
Built to real Factory Team specifications, the SUPERSPROX CST-546-16-1 brings professional racing development to your motorcycle. It is produced by the company that supplies genuine factory racing teams, offering a high-performance replacement or gearing-tuning solution for riders who demand durable materials, reduced friction, and race-proven design.
