Description
Polini Hi-Speed variator Kit
Tuning variator kit "Hi-Speed" by Polini.
The Hi-Speed is the improved successor of Polini's famous "Speed Control" CVT. Pulley angles were redesigned for better acceleration, sleeve and overall build were reinforced and improved.

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.
Scooter CVT Kit
The CVT system of a scooter includes a number of components responsible for transmitting engine power to the rear wheel.
Variator kits consist of:
Depending on the manufacturer, CVT kits may also include one or more contra springs or a clutch and clutch bell.
The different types of CVT kits
- CVT kit original: these kits contain OEM quality CVT components, the CVT transmission can be reset to the original condition.
- CVT kit Sport: Sport transmissions differ from OEM transmissons by a lighter variator, a modified angle and a special lining aimed at improving top speed as well as acceleration. In most cases the kits come with a reinforced belt.
- CVT kit Overrange / Oversize: Oversize kits have the same improvements as the Sport variants, but are also characterized by larger dimensions and are used with a longer oversize V-belt. This configuration improves the performance of your scooter quite a bit.
To simplify the installation of a new CVT, we strongly recommend the use of appropriate tools, especially a piston stopper, which is very practical for the removal and installation of a CVT transmission.
