Notes and Safety

Polini For Race

The For Race series from Polini includes exhausts as well as crankshafts and clutches for scooters, 50cc supermotos and Vespas. Although the name sounds like ultra-high-quality and high-performance racing parts, this is not quite true.

The exhausts are not road-legal and are theoretically only intended for use on the race track, but due to their performance, which focuses mainly in the lower and medium RPM range, they are more suitable for sports / entry level tuning setups, which are appreciated for their balanced ratio of performance and reliability for everyday use.
The crankshafts are also suitable for sports cylinders, as are the few For Race clutches.

Polini fans looking for maximum power for the racetrack should therefore opt for the Evolution or even the P.R.E. series.

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.
