Polini hi-speed variator kit for scooters using a Piaggio 50cc 4-stroke 2/4-Valve or fuel injected 50cc 2-stroke engine.
Ideal replacement for the expensive standard unit, but with added extras. The reduced weight and friction the team at Polini have achieved not only helps improve acceleration but top speed as well.
*Supplied with 4.7gr - 19x15.5mm rollers
Now includes torque spring.
Not suitable for 3-valve (iGet) engines, you would need this one here.

No, it isn't possible for any variator to give a higher top speed than a stock variator except wwith kits where the rear torque driver AND the variator are larger diameter and come with special (normally longer) belt.
These kits are available but very expensive and not the best way to increase top speed.
If you increase the diameter of just the variator it doesn't work because the belt can only move a certain amount due to the restrictions of the rear torque diameter and the belt would not use the extra diameter.
To increase the top speed you need to change the overall gearing using primary or secondary gear kits.
