Description

Improve acceleration on your stock Vespa or Piaggio 3-valve 4-stroke scooter with this complete Polini Performance Transmission Kit. Designed specifically for the 125cc and 150cc 3V (3-valve) engine platform, the kit replaces the entire CVT variator assembly with performance-spec components including a matched ramp plate, two roller weight options, 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.
