Description
Clutch 107mm - original spare part Minarelli 4T.
Yamaha is a Japanese motorcycle manufacturer known for the quality of its products.
Scooters have a so-called centrifugal clutch, with almost perfect efficiency of transmission of engine power to the gearbox. The clutch must match the setup, for tuned engines the clutch should also be upgraded, a tuned engine with significantly higher power rpm is undriveable without a sport/racing clutch as it has no power in the lower rpm range.

Scooter clutch
The clutch is essential for the smooth operation of the scooter's automatic CVT. It ensures that the engine power is transmitted to the rear wheel in a continuous and controlled manner.
How Does a scooter clutch work?
The clutch and clutch bell of the centrifugal clutch on scooters form a single unit. The clutch bell is attached to the input shaft of the engine. When the engine reaches a certain speed, the clutch shoes with linings are pulled outward by centrifugal force. Clutch and bell come into contact, they engage so power can be transmitted from the engine to the rear wheel.
How to adjust a Scooter clutch?
Scooters are centrifugal clutches, with increasing RPMs the centrifugal force leads to clutch engagement. The clutch springs play an important role in this process as they affect the engine speed at which the clutch engages, i.e. makes contact with the bell.
The clutch engages at a lower engine speed with soft springs, while hard springs delay clutch engagement. It is important to find the optimum compromise in terms of setup and intended use.
More precise settings can be done with an adjustable clutch, where the tension of the clutch springs can be adjusted.
We carry a wide range of special tools for hassle-free assembly and disassembly of clutch and transmission parts.
