The Polini Max Hi-Speed is one of the most drivable variators available for Maxi Scooters. Real attention has been paid to the build quality that makes better use of the belt than the original variator. This means that the ratio of the variator changes in low-torque situations. This results in improved acceleration and higher top speed. Both reliability as well as the build quality are markedly improved over the original. A sealed slider bearing with cleanly machined bearing bushes greatly reduces friction and the build up of gunk when sliding. The result is perfect shifting and longevity from reduced friction. Variator weights: 25x14.8 (13g and 15g). Delivery as pictured.
