Racing Clutch - Performance GY6 50cc QMA/ 50cc (139QMB) Engines

Racing Clutch for GY6 50cc and 139QMB Engines

This racing clutch fits GY6 50cc and 139QMB engines and is aimed at quicker acceleration and better overall performance. Its lightweight clutch parts are paired with strong 2000 RPM springs, which help the scooter pull away faster and respond better through the mid-range. Among the GY6 50cc scooter parts available, this one lets the engine engage at a higher power band, which can reduce bogging when you first open the throttle. It is a good pick for riders who want sharper throttle response.

Build and Quality

This clutch is made in Taiwan to ISO 9001 standards and is built to last. Compared with standard OEM parts, it handles heat and wear better, so it suits anyone planning a performance upgrade.

Performance Advantages

The clutch is designed to give quicker throttle response. It comes with 2000 RPM red springs already installed, which help the engine reach peak power earlier for a livelier feel on the road. It is a practical option if you want better acceleration without giving up performance.
