Yamaha Zuma 50 Gen 4 Performance Clutch 107mm (Standard)

Yamaha Zuma 50 Gen 4 Performance Clutch 107mm. This clutch connects to the rear wheel as engine speed climbs, and its springs determine the RPM at which it begins to engage. It is designed to fit the Yamaha Zuma.

A clutch that is worn may shudder, slip, or engage later than it should. Stiffer springs bring engagement in at a higher RPM, which gives stronger launches. Check the clutch bell diameter and confirm fitment for your engine before buying.

Product details

Upgrade your CVT drivetrain with the Generation 4 Performance Lightened Clutch, a 107mm racing clutch assembly in a green finish. Its lighter pillow blocks and heat-stable, high-friction pads reduce rotating weight, so the engine reaches peak power sooner. The result is sharper throttle response and quicker starts from a standstill.

Key Features

• Lightened Pillow Blocks: Lower rotating weight gives quicker throttle response and faster RPM build-up.
• High-Friction Pad Formulation: A custom composite blend helps prevent shudder on takeoff and pad glazing.
• Pre-Tuned Spring Calibration: Comes with 2000 RPM red sport clutch springs for a launch tuned to high performance.
• Signature Green Coating: The durable finish helps resist corrosion and damage from road debris.
• Transfers torque consistently, without fading at extreme operating temperatures.
