After WWII the aircraft factory began building three-wheelers with horizontally opposed twins. In 1956 th Chimera 175 ohv made its appearance.
Harley purchased Aermacchi Sprint moto in 1961 to produce small bikes for the American market. In an attempt to capture a piece of the young customers back from Honda. Harley sold Aermacchi in 1978 to the Castiglioni brothers, who built Cagiva from it, which was bought out by Ducati in 1985, and later Husqvarna and Moto Morini. At first, Harley-Davidson only imported the 250-cc Sprint. These are nice little bikes, with a spine frame, and a laid-down four-stroke engine that is similar to that used in the Moto Guzzi Falcone. More specs and user manual of Aermacchi Sprint you can see in next overview.
