This expensive, long legged late 1960s Italian design, badged American Eagle for US, was favored by Evel Knievel for his tricks until he got a new sponsor, Harley Davidson. He set a record jumping 17 cars at Ascot in his American Eagle. Very handsome bike, it was engineered by Massimo Laverda by reverse engineering a Honda 305cc CB77, a Norton 650SS and a BMW 69S. It made 60 hp stock but this bike is a mild custom by Moto Borgotaro in Brooklyn, where you can see much better pics of this bike. Wiki here.
