Variomatic Polini Hi-Speed Evolution 2 16mm, for Minarelli

Description

Polini Variator Hi-Speed Evolution 2 Minarelli horizontal, tuning variator by renowned Italian manufacturer Polini. As it was developed to be used with the original torque drive, it has to be used with a standard (preferably reinforced) drive belt. Pulley angles were designed to improve acceleration (compared to stock variator).
This is the EVO 2, the further developed and improved version of the already very powerful Hi-Speed CVT.Polini drew on their considerable racing and tuning experience to design a CVT that represents a definite upgrade to the stock part, with smooth and stable transmission and better acceleration from take-off to top speed. Your scooter will rev up a bit more aggressively and reach higher top speeds.
For the EVO 2 version the Polini engineers opted for a DLC (Diamond Light Carbon) bushing – light, low friction, sturdy. Two high quality oil seals ensure constant lubrication. The cores of the variator roller weights have polished sliding surfaces, the outside shells come with a heat- and wear-resistant Nylon / Aramid coating. The contra spring (plus anti-torsion spring seat) has a spring tension of +8%, so it is a bit harder than the stock spring.
The Polini Hi-Speed is the perfect CVT for any Sport or even Racing set-up.
Included:

variator with ramp plate
2 sets of 6 weights 19×15,5 mm (3.2g + 3.8g)
torque spring with Evo Slider
1 tube of pulley grease
