It would not be inaccurate to state that the progenitor of the superbikes of the 1970s was this four-cylinder model, the Honda CB 750 Super Sport. This incredible bike featured an air-cooled engine and an in-line overhead camshaft. The snappy lines and aerodynamics round off one of the most powerful and successful motorbikes of the 1970s. The CB 750 SS is a member of the AMA Motorcycle Hall of Fame Classic Bikes.
