Description
Performance Clutch Stage6
The Stage6 Sport Pro sport clutch for Minarelli scooters. Fits all models with 107mm clutch.
What is the benefit of a performance clutch?
The 3-shoe clutch can be adjusted by 2 lock-in positions and by choosing different clutch springs. In contrast to the original clutch, this allows changing clutch engagement, it can be adapted to the individual setup, i.e. the engine engages later. Clutch shoes and retainer ring are reinforced, everything is held in place by screw-in bolts (not simple rivets with a tendency to get loose).
This part is designed for use with 50/70cc sport to mid race engines. Better take-offs, longer lifespan, fair price - this clutch kit is definitely on our favourites list. For racing and high-end engines, we recommend the Torque Control by Stage6.
- Diameter 107 mm
- With 1x set of clutch springs (medium)
Attention: Minarelli engines started being equipped with different clutches in 1998. Please check if you need a 2-shoe (d = 105mm) or a 3-shoe (d = 107mm) clutch; you can also measure the inner diameter of the bell to find out what type you need.
Note: we recommend to use the spring seat (included) for the torque spring for Minarelli engines only (Aerox, Malaguti, Chinese scooters etc.). It is not recommended or necessary for Peugeot, Piaggio and GY6 4-stroke engines.
Stage6 Sport Pro
The Sport Pro series from Stage6 consists of various CVT components. The variator, clutch, V-belt and complete kit are designed for sport and racing setups.
Stage6 has revised shapes and materials to improve the performance of the CVT compared to the original and to adapt it to the performance increase after installing a sport cylinder.
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.
