The Clutch Performance V4 is a high-performance centrifugal clutch kit designed for scooters equipped with 125cc to 150cc GY6 engines (e.g., Honda Ruckus GY6, Kymco, PGO, Sym). It replaces the original clutch with an assembly optimized for:
more immediate torque engagement,
a more direct CVT transmission response,
improved slip-free power transfer,
increased durability under dynamic operating conditions.
This Performance V4 kit is calibrated to efficiently utilize the engine's usable power band, reduce losses during clutch-to-belt transition, and provide more consistent and predictable traction.
The term V4 generally refers to an internal generation/development of the product, featuring improvements to friction, springs, and friction profiles compared to previous versions.
