Polini Maxi Hi-Speed Variator Kit for Vespa GTS/GTV/GT300

Polini Maxi Hi-Speed Variator Kit for Vespa GTS, GTV, and GT300 Models

This Polini Maxi Hi-Speed variator kit is built for Vespa and Royal Alloy scooters, aiming to enhance acceleration and top-speed potential. Its nine-roller arrangement is designed to deliver smoother starts by spreading thrust more evenly than conventional six-roller designs. Among Vespa scooter parts, it is a practical choice for riders who want more usable power from their machine.

Smoother Acceleration

The nine-roller layout works to reduce shudder when you first pull away. Two integrated O-rings cut down on sliding friction, helping the scooter move from a standstill more efficiently and respond more readily as you ride.

Performance Tuning

This kit includes a larger pulley that can improve performance when the roller weights are matched correctly. It gives you room to adjust shift behavior to suit your engine and transmission, with the aim of getting the most from both acceleration and top speed.
