Vespa Primavera 125 Sprint 125 Piaggio Liberty 125-150 POLINI Evolution Hi-Speed Variator Kit

Vespa Primavera 125 Sprint 125 Piaggio Liberty 125-150 POLINI Evolution Hi-Speed Variator Kit

The POLINI Maxi Hi-Speed Variomatic Kit was especially developed for use in the Primavera and Sprint 125cc models and the Piaggio Liberty 125-150cc models. Consequently, the pulley weights, ramp angles etc. are exactly matched to the weight and wheelbase of these particular models and not just the QUASAR motor, unlike the practice of certain other manufacturers.

The new Polini variator for Piaggio - Vespa 125 4 stroke in the "original" version has been developed and designed to increase performance at an extremely competitive price compared to the Evolution model.

The Polini variator for Piaggio improves the performance of the engine as it guarantees greater acceleration and at the same time a smoother progression at speed.

The bushing is made of nickel-chromium steel and is characterized by a very low friction coefficient: it features the advanced carbon-based DLC treatment, an innovative technology for racing and aeronautics, especially for sliding components and parts subject to high wear.

The large inner pocket of the bushing has the function of a grease reservoir:
Inside there is a special spring that allows a constant distribution of grease on the pin even under the toughest operating conditions.
