In most states, you need a license that specifically indicates that you have taken and passed written and on-street tests covering the safe operation of a motorcycle.
In Massachusetts, according to the DMV website, "a Class M permit, Class M License, or Class M endorsement is required to operate a motorcycle." If Flynt/Wu is actually riding her little scooter around town, I'd say the chances are good to excellent that he hasn't bothered to get the correct license or endorsement. Laws -- much like simple human decency and common courtesy -- are for the little people.
