Description
Over time, the pulley´s surfaces that are exposed to friction become worn. This has a negative effect on the drive belt and can lead to serious damage. As soon as you discover signs of wear, you should get a new pulley.
This Piaggio Pulley Vespa GTS / GTS Super / GTV / GT 60 250-300cc is an original replacement pulley. OEM part, meaning it is identical to original part.
d=130mm.
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.
