I'm looking for a movie its set in the fifties or sixties and there is this teenage preppie kid and a guy with a motorcyle moves next door. The guy with the motorcyle is kind of a tough guy and winds up befriending the little preppie kid and winds up fighting the town bully and winning and keeps them off the young kid. The tough guy winds up with the popular girl and they run away together on a motorcyle leaving the preppie kid alone. The preppie kid is going home and runs into the bullies always picking on him and there is a car duel, I think the preppie kid was driving a blue studebaker. Does anyone know the name of this movie?

Sounds like "Mischief"
