Aprilia & Vespa Scooter Racing Parts - Woodruff Key Upgrade - Top Performances Crankshaft Key for Aprilia, Derbi, Italjet, Piaggio, and Vespa Scooters
The Top Performances Lima wedge is specially ground and thus enables an ignition offset in the direction of pre-ignition of the rotor. The slightly earlier spark ensures a more optimal timing and performance-oriented combustion at higher speeds. As a result, this small but fine component still provides a lot of performance potential for an original series ignition. Even with de-throttled production vehicles, the wedge is already useful. Great idea for really little money.
The worm for the generator rotor fixes the rotor on the crankshaft. The rotor triggers an ignition pulse after each revolution on the inductive sensor and thereby determines the ignition timing.
Please check the applications list prior to ordering since it works on both classic Vespa Mopeds and Scooters as well as modern models. See applications tab for all the Aprilia, Derbi, Italjet, Piaggio, and Vespa Scooters Models listings. References: 39691 9909940 4057237603517
Attention, do not assemble the wrong way around! Otherwise the opposite happens. B>
