Polini Variator "Hi-Speed" Malaguti F12 / Phantom (after 2000)

Polini Variator "Hi-Speed" Malaguti F12 / Phantom (after 2000), tuning variator "Hi-Speed" by Polini.

The Hi-Speed is the improved successor to Polini's famous "Speed Control", with better roller tracks. The angles of pulley and ramp plate were also redesigned to improve acceleration.

It comes with 16x13mm roller weights and a reinforced torque spring. We recommend testing different weights to further improve shifting and performance.

As it was developed to be used with the original torque drive, it has a standard diameter and has to be used with a standard torque drive and a standard (preferably reinforced) drive belt. 

Best used with a sports exhaust, 50cc sports to racing configurations.

Note: The CVT is intended for F12 models with 13mm crankshaft stub. Since 2000, the F12 comes with a wider variator cover and the stub was extended by 1cm, an approx. 1cm thick washer is included with the kit.
