GY6 Performance Clutch Drum for 125mm CNC

Performance Clutch Drum for GY6 125cc and 150cc Vehicles

The Snowflake Performance Clutch Drum is built to improve the output of a GY6-powered scooter or all-terrain vehicle. Machined from lightweight aluminum on a CNC mill, it serves as an upgrade over the stock steel bell. Browse our GY6 scooter parts range for related components. This drum is intended to engage the clutch more quickly and respond better to the throttle. It comes in three anodized finishes—Black, Gold, and Silver—so you can pick the look that fits your machine.

CNC-Machined Aluminum Design

The drum has a snowflake and honeycomb cutout pattern that cuts down on rotating weight. Because it is lighter than the heavier stock option, it can deliver a noticeable difference in responsiveness. Its 19-spline inner bore provides a firm, secure fit with your current setup.

Direct Replacement for GY6 Engines

This clutch drum is made to replace the original part on GY6 152QMI and 157QMJ engines, the models typically found in 125cc and 150cc vehicles. You can remove the old drum and fit this one in its place without extra modification, which keeps the job simple.
