Description

Polini's HI-SPEED variators for 50cc engines are now also available as extensive variator kits. They are of high quality and feature an optimised ramp design. Furthermore, every kit includes a torque spring that prevents belt slip and thus ensures better power transmission. The really cool thing is, however, the evo slider, a kind of guide plate that tackles the problem of twisting torque springs. Depending on which kit you get, there may also be a set of reinforced clutch springs included that will make the clutch engage later.
Scope of delivery: variator, drivebelt, 2 torque springs, 2 sets of weights (5.6 + 6.9g), 1 set of clutch springs

Notes and Safety

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.
