Segment: Clasic
Production years: 1959, 1960, 1961, 1962
With production of the overhead camshaft singles well underway for 1958 the Formula 3 superseded the Marianna (the Gran Sport's nickname) as a catalogued production racer. The F3 was first offered as a 125 and 175, and from 1960, a 250, and was still largely Marianna based. Almost nothing, however, from the production street bikes was used in the F3.
