NCY Performance Racing Clutch for GY6 50cc / 139QMB
Upgrade your takeoff and mid-range acceleration with the NCY Racing Clutch. Specifically engineered for 50cc 139QMB engines, this premium clutch features lightweight gray clutch shoes and stiff 2000 RPM red springs. By allowing the engine to reach a higher power band before engagement, you’ll experience a snappier throttle response and eliminate "bogging" during initial acceleration.
Manufactured in Taiwan to ISO 9001 standards, NCY is the trusted leader in aftermarket CVT performance, offering superior durability and heat resistance compared to stock OEM components.
