The Polini Evolution fork for Vespa Small Frame is interchangeable with the original, reinforced at the points most subject to structural stress, allowing the installation of a more powerful braking system like that of the Zip SP scooter.
The Polini fork is designed to accommodate the original handlebar; the steering lock and cable passages remain unchanged as with the original fork.

Digital ignitions are mainly used on high-end engines. The Polini PVL2020 ignition works up to 20,000 rpm, the rotor weighs only 660 gr which means we will have a much faster and more responsive acceleration reaching the maximum speed in less time... The CDI unit offers the added advantage of variable ignition timing. When the engine speed increases, the timing shifts towards the top dead center, significantly increasing the output.

Racing clutch disc series with 4 discs and reinforced spring. The clutch discs have been improved with a new material that increases the friction coefficient to enhance grip under stress.
