The SUPERSPROX Countershaft Sprocket is a 15-tooth sprocket designed for Yamaha applications. It features a carbon-free SCM-435 steel construction with an impregnated design intended to provide zero breaking risk and extended sprocket life.
An ultra-hard 0.02-inch surface layer helps reduce friction and power loss caused by chain drag. The sprocket is fully lightened with radial holes for off-road and street applications, while grooved teeth help remove dirt quickly in off-road use. This part is described as a Real Factory Team specification component from a company supplying real factory teams.
