Polini Hi-Speed Transmission Kit – Vespa/Piaggio 125/150cc
Description
Improve acceleration on your Vespa or Piaggio 3-valve 4-stroke scooter with this complete Polini performance transmission kit. Designed specifically for 125cc and 150cc 3V (3-valve) engines, the kit replaces the entire CVT variator assembly with performance-spec components including a matched ramp plate, two roller weight options for tuning, a 35kg torque spring, and high-temp grease — everything needed for a full CVT upgrade in one box.
Note: The shim must be fitted between the pin and the fixed pulley during installation.
