HPI Mini Rotor CDI for Puch, Tomos, Sachs, and Derbi pa501 Cast iron cylinderHPI mini rotor CDI for so many bikes. These are designed for Puch E50 and ZA50 engines but can fit Tomos, Sachs, Derbi, and more with minimal or no modifications. Unlike the internal rotor HPI, this setup comes with a built in 60w lighting coil. A good lighting coil, ignition curve, and you can adjust the stator without pulling the flywheel. Its a pretty great setup. We recommend using a resistor boot or resistor plug as well as a voltage regulator
