The MVT DD Digital Direct internal rotor ignition is an excellent choice for owners of Aprilia, Derbi and Gilera motorcycles with Euro 4 engines. This ignition system offers a unique combination of performance and everyday usability. In contrast to many other inner rotor ignitions, which were developed primarily for racing, MVT integrates a light and charging coil that can completely replace the original ignition. As a result, the entire on-board electronics are reliably supplied with power.The lightweight inner rotor significantly improves engine agility. The engine reacts more quickly to gas commands and the idle gas remains stable. Especially with two-stroke engines, a lightweight inner rotor is superior to the heavy original rotor and offers the best performance with absolute reliab.
