1965 AERMACCHI HARLEY-DAVIDSON ZEFFIRETTO SPORT 48 S

Frame no.: *66S6801*

Engine no.: *P942*

Aermacchi was an Italian aircraft manufacturer.  Formerly known as Aeronautica Macchi, the company was founded in 1912 by Giulio Macchi at Varese in northwestern Lombardy as Nieuport-Macchi, to build Nieuport monoplanes under licence for the Italian military.  After WWII the aircraft factory began building three-wheelers with horizontally opposed twins. In 1956, the rare Chimera 175 OHV made its appearance.

In 1960, Harley-Davidson acquired 50% of the Aermacchi factory and assumed complete control in 1974. Harley-Davidson purchased Aermacchi in 1961, to produce small bikes for the American market, in an attempt to capture a piece of the youth market back.

In 1965, Harley-Davidson brought a smaller two-stroke Aermacchi on the market, the Zeffiretto. The name “Zeffiretto” was used for the Italian market. This 48cc machine came as a moped, the 48NP (P for pedals) and without pedals, a no-ped, hence 48N with no P. The engine is 38x42mm, plain piston-port, CR 8.5:1, with 3 speeds actuated by a hand shift. The 48NP was built until 1965, whilst the 48N continued until 1972.

In the United States Aermacchi sold these motorcycles as the “Harley-Davidson M 50 and M 65”. The Zeffiretto / M 50 and M 65s were virtually unmarketable in Europe and in America, despite large advertising campaigns. In total only 200 examples of this rare Aermacchi Zeffiretto Sport 48 S (M 50 S) were built.

Harley-Davidson sold Aermacchi in 1978 to the Castiglioni brothers, who built Cagiva from it, which in 1985 bought Ducati, and later Husqvarna and Moto Morini.
