CVT Variator Polini Maxi Hi-Speed Evolution Vespa 300cc

Polini Variator "Maxi Hi-Speed" Evolution Vespa 300cc, tuning variator by renowned Italian manufacturer Polini. The Evolution features Polini’s patented internal lubrication system reducing wear of the variator sleeve (and consequently minimizing maintenance and extending its life) and allowing for efficient variation; check installation manual for more information. Angles, roller tracks and sleeve surface were improved again – minimum friction, optimum power transmission.

To get the most out of it, you’ll have to test and try different roller weights to find the weights that are most fitting for your engine.
