Description
The POLINI MAXI HI-SPEED Evolution Variator Kit is a technological marvel, designed specifically for use with Piaggio MP3 250/300 and Vespa GTS 250/300 Euro 3-4-5 scooters. Its fix half-pulley and the “Air Speed” mobile half-pulley are machined with diverse angles to let the belt engage more efficiently. This Variator Kit is complemented by a Kevlar belt of different sizes compared to the original, allowing for optimal exploitation of the variator opening degrees. With smoother pulley-sliding inside the crankcase, the POLINI MAXI HI-SPEED Evolution Variator Kit ensures both improved acceleration and a higher peak speed. Additional 10% compression spring load and a chromed nickel-steel piston pin with low friction coefficient are included as well.
