Description

Polini is one of the most renowned manufacturers of tuning parts for scooters and mopeds. Polini is taking their Maxi Speed clutch to the next level. The 3G version is the the completely revised and improved result.

While sticking to their successful adjustable spring preload system, they now equip their racing clutches with 3 instead of 2 shoes with improved lining. The clutch can be adjusted to any original or tuned engine set-up within a couple of minutes. The Allen bolts for spring preload adjustment are located on the outside of the clutch unit and can be accessed by simply taking off the clutch bell. This means that clutch can be adjusted without having to disassemble the entire clutch.

 Available for many different maxi scooter models.

Notes and Safety

Polini Speed Clutch

The Speed Clutch series from Polini covers the entire range of scooter clutches. Here you will find clutches for 50cc scooters and maxi scooters that not only improve clutch performance, but also the service life of the clutch compared to the original.

This series also includes several other variants, such as 2G, 3G, 3G Evolution and For Race. All clutches are reinforced to cope adequately with tuned engines.
As the name suggests, the For Race clutch is designed for the most powerful racing engines.

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.
