yeah JJ's bike is pretty hard into the motorcycle/scooter territory. its a mhr kit on a revo motor, isn't it?
i guess the point of fastest moped is kinda like, moped engine, moped kit, moped parts... something that is instantly recognized as a 'moped' kinda a subtle distinction but in my book the grand prix/revo, stuff like jcams derbi/scoot hybrid, etc. are too far into scooter territory. tony simoni's hobbit/vespa/derbi hybrid... mostly moped parts so i think its in the spirit
