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.
