Description
A quality front sprocket is foundational to reliable chain drive performance, and JT’s rubber-cushioned design eliminates the shock loads that prematurely wear both chain and sprocket teeth. This 17-tooth configuration delivers precise engagement while the OEM-proven cushioning technology—trusted by major Japanese manufacturers since the early 1990s—significantly extends drivetrain lifespan. Built from premium C45 and SCM415 chromoly steel with heat-treated surfaces, this sprocket combines durability with minimal weight for responsive acceleration.
