The Polini digital ignition racing ignition for scooters equipped with water-cooled Minarelli engines. The ignition greatly increases the charging voltage and adjusts the ignition timing independent of revs at every single turn. The fine tuning of the ignition is relatively easy thanks to the adjustable pick-ups and can utilise the existing rotor. The lightweight rotor guarantees a much better acceleration. The flywheel is made from a single solid block, to give a perfect balance, while the hub is made of special steel with high mechanical strength. The ignition has four different basic settings, to supply engines from 50cc up to 94cc.
