Description
Variator Polini Piaggio Vespino Alx - Delta.
Polini used their many years of experience and considerable know-how to develop a variator that, compared to the standard CVT, gets better performance out of the engine, with stable and efficient power transmission and improved acceleration throughout the entire rpm range.
- Revised roller tracks
- Improved acceleration and top speed
Including weights 16x13 - 4.4g + 5.6g
Fits the following models (according to Polini):

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.
