Re: 80cc? Is it really? And isn't 50cc a motorcycle?
Since they all look alike, ride it reasonably and you'll probably be OK. Around here, the law says 50cc and less than 25 MPH. I follow scooters with no license plates all the time down Creasy Lane at 40+ and the cops don't give them a second look.
But if you cross paths with one who's having a bad day they'll probably bust you for 28 MPH.
