The basis was the 125cc Oro engine. Two of these engines combined gave 250cc and 46 horsepower on the rear wheel. The 350cc had a bore and stroke of 61x59.5 and later 61x54, good for 347.6 and 347.2cc. After many modifications, good results were achieved at the racing-track in 1972. At the worldchampionship 250cc Pasolini finished 2nd and third at the 350cc race. The best results were achieved in '74, '75' and '76 when Walter Villa rides and Aermachhi turned AMF-Harley-Davidson.
