HI-Speed variator for Yamaha 4T from Polini

This Hi-Speed variator from Polini boosts your 4T scooter and is especially an excellent addition to a tuning cylinder.

Several areas of this variator are optimized compared to a standard variator:

• The variator housing is designed with a different slope so that the belt can travel better.
• The roller tracks have been treated with a glaze so that the rollers slide back and forth more efficiently.
• The supplied compression spring has an increased tension of 87%.
• The included trim springs for the clutch have an increased strength of 35% which raises the speed by 500 rpm before the clutch engages.

A variator like this can help the acceleration and cause your scooter to reach its top speed, faster.

Note: Polini recommends using this variator with their lambda emulator . 4.5 gr rollers, slide tubes, compression springs and trim springs are included.
