Yoshimura Valve Spring Set (White) – GSX1100S / GSX750S / GSX1100E

Built for the upper range.

This Yoshimura valve spring set is designed specifically for use with the ST-L2 camshaft—supporting stable valve control at higher RPM where performance demands increase.

Paired with lightweight titanium retainers, it reduces valvetrain mass and sharpens engine response.
