Brought to the United States by Harley-Davidson's Aermacchi division and joined by a quartet of more conventionally styled machines in 175cc and 250cc capacities. They were quite popular but perhaps slightly underpowered when compared to its Japanese counterparts. To satisfy riders who demanded more performance but also enjoyed smaller motorcycles, Harley-Davidson began to market the 250cc Ala Verde in America.
The Aermacchi 250cc Ala Verde is a stunning little motorcycle exuding Italian engineering and design from the 1960's. It is Sprint-like in its lines but hides a motorcycle with much more performance. The striking lines of the Harley-Davidson Aermacchi 250cc Ala Verde imply a sporting motorcycle with race inspired fuel tank and clip-on handlebars. The top end of the engine is quite different from the run-of-the-mill Sprint.
The sophisticated 2-valve OHV engine of the 250cc Ala Verde delivers 18 horsepower through a 5-speed transmission allowing the motorcycle to achieve up to 148 km/h.
