Description
A countershaft sprocket is your direct connection between engine power and wheel traction—weak material or poor design here means lost power, premature wear, and potential catastrophic failure mid-race. The SUPERSPROX CST-513-14-2 uses factory-grade SCM-435 carbon-free steel with an impregnated structure that eliminates brittleness while its ultra-hard surface layer (.5mm) minimizes friction-induced power loss from chain drag. Whether you’re pushing a dirt bike to the limit or maximizing street performance, this is the same specification trusted by factory racing teams.
