Performance Camshaft 50cc (139QMB) GY6 50cc

Performance Camshaft for GY6 50cc Engines

This performance camshaft is built for the GY6 139QMB engine and helps 4-stroke scooters run better. It is a worthwhile step up for anyone fitting a 72cc, 82cc, or 100cc big-bore kit. As one of the GY6 50cc scooter parts, it works to get more out of the engine by improving airflow and supporting higher RPMs. It is intended for off-road use only and suits riders who want to extend what their engine can do.

Better Engine Breathing

The lobe shape on this camshaft is refined to deliver more lift and longer duration than stock units. Greater volumetric efficiency lets the engine draw in and expel gases more effectively, which helps performance on the ride.

Precise Construction

A accurately machined 34-tooth timing sprocket is fitted, keeping the valves and piston in correct sync. The hardened steel core is made to handle the high RPMs and loads common in modified builds, offering dependable service for your scooter.
