Clutch Bell POLINI Speed Bell
for GILERA/PIAGGIO 2-stroke
Ø 135 mm
The Polini Maxi Speed is a powerful alternative to the expensive original variator for all Maxiscooters. This sports variator is built to comply with high-quality manufacturing standards. The bushing has improved lubrication through two fitted o-rings. This makes for less friction compared to variators of other competitors. The Maxi Speed Control achieved top results regarding performance and reliability in many performance tests! This variator is available in two versions – the "Maxi Speed Control" with 6/8 roller weights or the "Maxi Speed 9/12 roller weights" with 9/12 roller weights. The most obvious characteristic of the "Maxi Speed 9/12 roller weights" are the 9 or 12 roller weights as compared to only 6 such weights that are standard. Acceleration of your engine will especially benefit from the precise and evenly distributed axial load. The typical jerking of 4-stroke engines while starting the scooter will be reduced to a minimum due to a more even load distribution.
However, one thing that stays the same for both systems is: improved acceleration combined with a higher top speed!
SIP TIP: new variator nut, special / polyamide belt, additional roller weights for individual adjustment, holder tool
