For this reason Polini dedicates to the owners of Scooter 50cc, both with Piaggio and Minarelli engines, a concentrate of true sportiness, starting with the name. We are talking about hi-sued, a complete kit of variator, rollers, contrasting spring and evo-scarer, capable of making the temperament of your standard scooter more gritty and reactive, while maintaining safety and reliability. Hi-Speed has been studied with specific calibrations for the original scooter. The new semi -pulley, in die -cast aluminum alloy with a high silicon tenor, was produced with new inclinations of the roller slopes. Absolute novelty is the addition of the contrast spring with Evo-Slider. The Polini Evo-Slider, made of anti-wear and self-lubricating composite material, allows the contrasting spring to slide.
