HPI INTERNAL ROTOR flywheel - kinda uncut taper

hpi magneto with an taper so you can have it cut to fit any moped you desire.. this magneto will work perfectly with the puch and hobbit hpi stator plate assemblies we currently have.

HPI no longer sells a truly un-cut taper anymore. this is the smallest taper they offer which measures 15.40mm at the larger side and 11.32mm on the small side. good luck
