Description
Aluminium pulley with integrated clutch with 3 clutch shoes. Mounting a racing variator on your moped can, depending on model, mean that you cannot use the clutch any longer. This special ER2 clutch pulley by Doppler will bring it back; to be specific, the clutch is integrated in the pulley.
For MBK 51 mopeds with racing variators / variators without clutch function.
CVT Pulleys
Pulleys are an integral part of the CVT system on scooters and mopeds with automatic CVT transmission.
The continuously variable transmission consists of fixed and moving pulleys, the V-belt rises and falls between them depending on the engine speed, changing the speed of the vehicle.
When should you change a pulley?
There are two reasons for replacing pulleys:
- Wear and tear. Although pulleys are relatively durable, the constant sliding of the V-belt can deform the surface.
- Tuning. Different pulley angles and diameters can improve the handling of scooters or mopeds.
Note: A CVT variator can only do a good job when CVT pulleys as well as torque drive pulleys are compatible with each other. Pitches and diameters of the individual elements must be matched so that the V-belt can glide evenly.
