Spring internal D.31mm Polini CVT Maxi Hi-Speed

Polini Hi-Speed

The famous Polini brand lists their "Hi-Speed" CVT as part of their catalog for many years. Of course, the CVT has been upgraded and improved over time, but the basic principle is still the same: a tuning variator for original and slightly tuned engines with a noticeable increase in performance compared to the original variator.

Performance Polini High Speed CVT

With newly calculated and optimized angles, the Hi-Speed variator allows an extended power band. This shows above all in noticeably better acceleration, but also in a slightly higher top speed.

Two integrated O-rings provide the sleeve with better lubrication, resulting in less friction.

The low-friction, robust chrome coating ensures reduced wear and increased service life.

For heavily tuned engines and engines with a significantly larger displacement, it is worth using an overrange CVT.
