GY6 Aluminum Performance Outer Drive Face (115mm)

GY6 Aluminum Performance Outer Drive Face for 125cc/150cc Engines

This upgraded outer drive face is built for GY6 engines and aims to enhance how your ride performs. At 146 grams, it lets the RPM climb more quickly than standard steel parts do. It is one of the GY6 scooter parts that directly fits a range of 125cc and 150cc models, supporting dependable operation and efficiency.

Light Build

Constructed from aluminum, this drive face cuts down on weight while still holding up well. The reduced mass helps the engine respond more readily and accelerate faster, which suits anyone wanting more performance from a scooter or go-kart.

Exact Fit and Compatibility

With 19 splines and a 15mm inner diameter, the drive face grips the standard GY6 crankshaft firmly so it won't slip. Its standard 115mm outer diameter lines up with performance variators, allowing maximum belt travel and top-end speed. It works with a variety of engines, including those used in popular scooter and off-road models.
