Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

Supersprox Stealth Rear Sprocket

Supersprox Stealth Bi-Metal Rear Sprockets feature a patented combination of steel teeth and an aluminum core. This design delivers 3× the lifespan of aluminum sprockets while being up to 30% lighter than all-steel alternatives. By reducing friction, they extend chain kit longevity, enhance bike performance and appearance, and are available in various colors to fit 99% of street and off-road motorcycles.
