The Evolution Racing clutch and Hebo clutch are identical settings in principal. The Hebo clutch differs mainly in the clutch linings.
3 Shoe clutch with variable spring pre-load and supplied with 2 sets of different strength clutch springs for sporty scooters and fine tuning. The great advantage of this kit is that the spring preload can be adjusted by a hex screw on the back without having to take down the entire drive. Suitable for use with clutch bells with an inside diameter of 107mm.
Superb piece kit for the price and great for tuning transmission.
