how do u define moped when u start racing cuz tommy hit 70 (mad respect for any body willing to go that fast on a moped frame) on a engine that was what 110cc off of another bike if i remember correctly then on the single speed subject ZA-50s, Tomos engines Moby variators all are more than one speed it seems like its all an ocean of gray with diffrent style frames off limits like the cub or a Vespa
what r the rules
