Polini Hi-Speed Transmission Kit for Vespa/Piaggio 125/150cc

Polini Hi-Speed Transmission Kit for Vespa and Piaggio 125/150cc Scooters

This Polini Hi-Speed Transmission Kit is made for Vespa and Piaggio scooters with 125cc and 150cc 3-valve engines. It takes the place of the factory CVT variator assembly with upgraded parts. Its main purpose is to help improve acceleration and general performance. Like other Vespa scooter parts, it is set up for a fairly simple fitting process.

Performance Components

The kit comes with a full group of performance parts, including a variator, ramp plate, and roller weights offered in two sizes for tuning. It also includes a 35kg torque spring and high-temperature grease. During setup, the supplied shim goes between the pin and the fixed pulley so the system works correctly.

Installation Notes

This transmission kit is intended for off-road use only. It is not suitable for street riding. Take care during fitting so every component sits correctly, since this has a large effect on how the scooter performs. Routine inspection and upkeep of your scooter parts is advised to keep everything running well.
