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.

Precision CNC-machined from world-class 7076-T651 aluminum, they feature a special tooth design and mud-clearing grooves to extend chain and sprocket life, finished with high-quality durable anodizing in various colors.
