Description
Gold PTFE-Coated Variator Pulley for 50cc GY6 Engines
This variator pulley is built for 50cc GY6 engines, including the 139QMB. Its 89mm diameter suits a range of riding styles. It is one of the GY6 50cc scooter parts that may help the scooter pick up speed more quickly. Compared with stock components, its light weight is a clear benefit.
Build and Advantages
The pulley uses a gold PTFE-coated aluminum alloy body. The material keeps the weight down while also contributing to better output. It is designed to transfer power more efficiently, so it suits anyone looking to upgrade what their scooter can do.
Measurements and Compatibility
The variator pulley measures 20mm across the inner diameter, 89mm across the outer diameter, and 32.4mm in height. It works with several engine codes, among them 139QMA, 1P39QMB, and others. If the engine identification includes "QM" or "FM," this product should be a match for your vehicle.
