Upgrade performance with the Polini For Race analog ignition – product code 171.0563, designed for Vespa PK 50 and Ape 50 with Ø20 flywheel fittings and 5-wire dedicated wiring.

The kit features a lightweight flywheel (1.2 kg) with a 25 kg·cm² moment of inertia, delivering faster engine response, stronger acceleration and improved top-end performance.

Optional external inertia weights of 20 or 45 kg·cm² (sold separately) allow you to fine-tune engine response based on your riding style and setup.

The 12V 4-pole stator provides stable power for lighting and battery charging (if equipped). Integrated coil and ECU ensure reliable ignition management, while the improved fan design increases airflow for better cooling.
