Variator Polini Hi-Speed Evolution Honda SH 350 / ADV 350 / Forza 350 >2025

Variator Polini Hi-Speed Evolution for Honda SH 350, ADV 350 and Forza 350 up to 2025.

The Polini Hi-Speed Evolution variator is a racing-focused transmission component, developed to improve the response of the CVT system on 350 cc Honda scooters. Its function is to manage the transmission ratio together with the belt, rollers, and clutch, directly influencing how the engine delivers power to the rear wheel.

In a worn variator or one limited by a stock setup, less vigorous take-off, poorly progressive RPM changes, or a slower response when opening the throttle may occur. Replacing it with this Polini Hi-Speed Evolution variator helps achieve livelier acceleration, more direct power delivery, and a more responsive transmission, especially in sporty use.

This variator is intended for the Honda SH 350i, Honda ADV 350i, and Honda Forza 350 in Euro 5 and Euro 5+ versions. It is a recommended option when seeking to improve the behavior of the CVT automatic transmission without modifying the indicated compatibility for each model.
