The Polini Maxi-Speed 125 mm clutch is a high-performance centrifugal clutch developed for scooters equipped with GY6 125cc to 150cc engines, notably those used on platforms such as the Honda Ruckus GY6 and other derivatives. Designed to replace the original clutch, this kit is distinguished by superior torque management, more responsive traction, and improved transmission consistency for dynamic or sporty road use.
The Maxi-Speed version focuses on:
Optimized torque engagement
Reduced slippage
Improved throttle response
Support for slightly modified engine configurations
With a 125 mm friction diameter, this model maintains a standard GY6 compatible profile while increasing the efficiency of power transfer to the CVT transmission.
