Description

Polini Maxi Hi Speed CVT for Sym 300 Euro 5

We offer you the Polini Maxi Hi-Speed variator for maxi scooters at a top price-performance ratio. The Polini Maxi Hi-Speed is one of the most powerful CVTs for maxi scooters.

Advantages of the Polini Hi-Speed CVT

The roller tracks make better use of the engine's power band than the original variator. This changes the transmission ratio to a more favorable torque range, which results in better acceleration and a slightly higher top speed.

A sealed bearing with cleanly processed bearing bush reduces friction, which leads to optimized shifting and longer service life due to reduced wear.

Technical data Maxi Hi-Speed:

Supplied with a set of rollers weighing 14.2 g
Roller coating made of durable nylon and aramid fiber
CVT bushing made of chrome-plated steel with DLC treatment (Diamond Like Carbon): improved friction coefficient and minimal wear
Grease-lubricated sliding bush with seals
Specific treatment of the roller tracks for reduced friction
Including contra spring +30% (better responsiveness when starting)

Note: Polini recommends lighter rollers for sporty use. We recommend carrying out test runs and adjusting the weights. The Polini CVT tuning set is ideal for doing this.

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

Modern scooters are equipped with a continuously variable transmission, the so-called CVT, also called variator.

CVT Parts:

Front pulley, movable. It contains the variator weights and has a special shape with an inclined surface to allow the V-belt to move freely up and down.
Ramp plate: Holds the weights in place.
Variator sleeve: Serves as a bearing for the variator, which moves axially back and forth, i.e., opens and closes.
CVT roller weights: Adjustment weights that play a critical role in function and performance.

original, Sport and Oversize CVTs

Original: Original or OEM quality CVTs are equipped with a restrictor to limit the speed to 45km/h. There are riders who remove the restrictor to derestrict their scooter and unleash the full performance without restrictions.
Sport: Sport CVTs are lighter than the original and are characterized by special angles and a special coating, which increases the top speed, but especially acceleration.
Oversize: Based on the same principle as the Sport CVT, but has larger dimensions. With an oversize / overrange vario, the performance of the scooter can be increased even further.

You should also always replace the V-belt when replacing the CVT or go for a complete CVT kit.
