Supersprox 13-Tooth Countershaft Sprocket (CST-1590-13-1)

Upgrade your motorcycle’s drivetrain with the SUPERSPROX CST-1590-13-1 13-Tooth Countershaft Sprocket, engineered for demanding off-road and street applications. Made from SCM-435 carbon-free steel, this sprocket delivers dependable strength and durability while its specialized manufacturing process helps ensure a low risk of breakage and extended sprocket service life. The genuine SUPERSPROX design is built to support consistent power transfer in demanding riding conditions.
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 CST-1590-13-1 can help reduce drivetrain power loss and promote smooth, efficient operation. This surface treatment also contributes to long-term wear resistance, making the sprocket a practical choice for riders who expect reliable performance from their motorcycle’s final drive system.
Fully lightened with radial holes, the SUPERSPROX countershaft sprocket helps reduce unnecessary rotating weight without compromising its purpose-built construction. Grooved teeth are designed for off-road use, allowing dirt and debris to clear more quickly from the chain engagement area. The result is a sprocket suited to both street riding and demanding dirt environments, with design details inspired by SUPERSPROX factory racing components.
As a genuine SUPERSPROX part, the CST-1590-13-1 reflects the specifications and performance-focused engineering used by the company’s real factory racing teams. Its 13-tooth configuration is intended for compatible motorcycle applications and should be matched to the vehicle’s chain size, drivetrain setup, and manufacturer requirements before installation.
