SSP-G GY6 Performance Clutch Drum - 12 Spoke

Cooling Under Pressure: SSP-G 12-Spoke Performance Clutch Bell

Eliminate clutch fade and improve take-off consistency with the SSP-G 12-Spoke Performance Clutch Drum. Engineered for 125cc to 170cc GY6 engines, this high-performance bell features a specialized 12-spoke vented design. This open architecture drastically improves airflow within the CVT case, allowing heat to escape rapidly and preventing the clutch pads from "glazing" during aggressive stop-and-go riding or off-road use.

Technical Performance Features

• Vented 12-Spoke Design: Maximizes heat dissipation to keep clutch temperatures low, ensuring a consistent bite and preventing power-robbing slip.
• Precision Balanced: CNC-machined to exacting tolerances to eliminate high-RPM vibration, protecting your final drive bearings and ensuring a smooth power delivery.
• Enhanced Friction Surface: The internal drum surface is optimized for rapid engagement, reducing "shudder" during low-speed take-offs.
• Universal GY6 Compatibility: Features a standard 19-spline interface, making it a direct-fit upgrade for nearly all 150cc-based 4-stroke scooters, ATVs, and karts.

Comprehensive Fitment Guide

This performance drum is a direct replacement for 125cc / 150cc / 170cc engines with the following codes:

Technical Specifications

• Inner Diameter: 125mm
• Outer Diameter: 136mm
• Number of Splines: 19
• Spline Diameter: 13.5mm (Peak) / 15mm (Valley)

Mechanic's Note: Heat is the #1 killer of GY6 clutches.

Performance Tip: If you notice your scooter "shaking" or losing power on take-off after it gets hot, your stock bell is likely trapped heat and glazing the pads.

Installation Tip: When installing this new bell, always use a Clutch Holding Tool to torque the nut to factory specs; never use an impact wrench alone, as it can deform the splines!
