Polini Hi-Speed variator

The CVT's job is to properly translate the engine's power at its optimal RPM. The Polini Hi-Speed variator comes with 16x13mm / 6.9g rollers (corresponds to the setting when using the original exhaust) and with a reinforced contra spring.

The roller tracks of the Hi-Speed have been optimized compared to the previous model. The scooter accelerates better, and top speed is increased, as long as you use the correct weights. We recommend testing different weights to further improve shifting behavior and performance.

It is compatible with a standard-size belt, but we highly recommend using a reinforced belt.

The “Hi-Speed” tuning CVT is recommended for 50cc sport/racing setups.
