HPI Inner Rotor CDI for Puch, Tomos, Sachs, and Derbi

HPI inner rotor CDI for so many bikes. These are designed for Puch E50/Z50/ZA50 engines but can fit Tomos A35 and A55, Sachs 505, Derbi Piston Port/Pyramid Reed/Flat Reed, and more with minimal or no modifications. Lightweight rotor, built in ignition curve, and you can adjust the stator without pulling the flywheel. Its a pretty great setup. Stator color may vary. Usually they are red, black, or gold. ******These do NOT come with a lighting coil! You will need to purchase separately or run your lights off a battery.
