How to reach this goal? The most important step is to replace the CDI with the new Polini ECM “Engine Control Unit” with valves springs. It is very important to change the CDI for the setup. The addition of the valves springs in the packaging lets the limiter reach 10.000 rpm with better results in terms of speed and a performance increase that grants smoother and more dynamic driving. Depending on the assembly steps of your scooter it is important to match the proper map developed by Polini.
Polini presents the new mufflers for Vespa 300 with Euro 5 homologation. The higher performance of the exhaust system grants the engine the best yield, by improving acceleration and pick-up. The silencer made of black anodized light alloy stands out for its new design. The muffler is also available with catalyzer.

The head with increased finning over the entire surface allows the achievement of maximum heat dispersion.
