Apart from motorcycle documentaries, of which "On Any Sunday" remains without peer, and Moto X movies like the Krusty Demons , etc. what movies featuring motorcycles have taken your interest? There was a horrible 70's movie that I saw once that featured racing in southern California on old TZ's and things like that. It was a a dog of a movie, but the action sequences were real racing and it was very interesting to see how it took place back then. Can't remember what it was called, though.
