The Polini Hi-Speed is the ideal solution for bringing your 50cc scooter to life. Designed specifically for Piaggio's and Vespa's modern i-GET engines, this variator gives a clear upgrade in acceleration and in the smoothness of the transmission. Where the factory settings hold performance back for consumption reasons, Polini steps in with redesigned roller tracks, letting the engine work in its optimum rev range. The result is quicker getaways at the lights and better response on hills, making everyday journeys around town more comfortable and more enjoyable.
