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.

With the RS Racing, Polini has added a sporty version to the already available "original" version.
The modified manifold makes the system suitable for large
displacement cylinders and higher regimes, which is also reflected in the
larger diameter of the exhaust terminal. The RS Racing is obviously noisier than the standard version. It is suitable, for example, for the Polini 133 Alu or even the EVO.

POLINI RS RACING FEATURES

Larger manifold (Ø29 mm)


Modified cone


Larger exhaust pipe


Also suitable for wide 3.50-10 tires


Pleasant sound emission


Available for Vespa PV/ET3


The wonderfully antique look, with the exhaust pipe exiting
sideways like the well-known "banana", perfectly hides the
elaborate internal construction, including sound insulation. The
only external clues to the modern design are the elastic suspension
of the exhaust through a silent rubber on the crossbar and the
two-part, spring-loaded
