A scooter with a spare tire is the best place to start. I drive my Heinkel anywhere- I have been to Bar Harbor, Maine and NYC. My uncle, who bought it new in 1960, took it off the showroom floor and went from DC to LA by way of Mexico. You just have to keep the revs within safe limits. He made the trip in the late 50s on a Vespa. Said he liked the Heinkel better, larger and more comfortable, and got more respect. It has gravitas.The Stella is probably your best bet. A flat tire will hold you up for a half hour maybe.
