Polini Hi Speed Variator/Belt Kit Minarelli

The Polini Hi-Speed kit is a transmission assembly designed to improve and optimize the operation of the CVT on scooters equipped with a compatible Minarelli engine.

The kit includes the Polini Hi-Speed variator and its Polini 248.003 belt, as well as two sets of rollers with different weights and two clutch springs, allowing you to adapt the transmission setting to your engine configuration.

With 5.6 g and 6.9 g rollers, as well as 22 kg and 28 kg clutch springs, several adjustment possibilities are offered to achieve the desired behavior according to your engine.

Technical specifications:

• Brand: Polini
• Range: Hi-Speed
• Application: Minarelli
• Rollers: 16x13 mm
• Roller weights: 5.6 g and 6.9 g
• Clutch springs: 22 kg and 28 kg
• Belt reference: Polini 248.003

The choice of rollers and clutch spring directly influences the engine's operating speed, acceleration, and transmission behavior.

We recommend testing the different combinations included to adapt the setting to your engine configuration rather than considering a single setting as ideal for all scooters.
