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

The Polini Maxi Hi-Speed ​​is one of the highest-torque variators in the maxi scooter range. Particular emphasis was placed on the design of the roller tracks, which utilise the engine’s existing power band far better than the original variator. This means that the variator ratio changes in low-torque, low-rev situations. This provides greater acceleration and slightly more top speed. The package includes a set of roller weights measuring 25x21.8 and weighing 14.2 g, a 23% stronger counterpressure spring, and a set of slides.
