variator Polini Maxi Hi-Speed for SYM GTS, Joymax 250-300 241.742

The Polini Maxi Hi-Speed ??is one of the highest torque variators in the maxi scooter range. The emphasis was placed on the construction of the roller tracks, which utilise the existing power band of the engine in a far better way than is the case with the original variator. This means that the ratio of the variator changes in low-torque, low-rev situations. This provides greater acceleration and a little more top speed. The package includes a set of roller weights 25x21.8 with 14.2 g, a 23% greater counterpressure spring and a set of slides are included.
