With Phil Aynsley

Aermacchi’s first four-stroke mannequin was the 1956 175 cc Chimera. The OHV motor was quickly used for competitors within the type of the 1957 175 Ala d’Oro (Golden Wing). This produced 16 hp at 8000 rpm and went on to be the principle competitors to Morini’s Settebello in Italian nationwide racing.

A 250 cc model appeared in 1960, turning into the corporate’s first entry into Grand Prix racing. Initially producing 22 hp this was elevated to 26 hp by the next yr and 28 hp in 1962.

In 1963 the motor was redesigned to make use of a shorter stroke (72 x 61 mm) with output elevating to 32 hp at 10,000 rpm.

Aermacchi then launched a 350 cc in 1964 (74 x 80 mm) that made 33 hp at 8000 rpm. Whereas the bike by no means received a GP race, Renzo Pasolini completed third within the 1966 championship and Kel Carruthers repeated that podium feat in 1968, by which era the bike’s output was as much as 42 hp at 9000 rpm.

Manufacturing unit rider Alberto Pagani scored a ninth within the Dutch TT at Assen within the 250’s debut yr (1960) and adopted that up with a fifth place on the Belgian GP. On account of this promising starting the corporate started providing a restricted variety of manufacturing racers (the DS) from 1962.

Output was a lowish 28 hp at 9000 rpm, however with good low-end torque and a lightweight weight of 102 kg, total efficiency was aggressive.

The long-stroke (66 x 72 mm) motor used a four-speed gearbox and the highest velocity was simply over 160 km/h. The bike seen here’s a 1962 250 cc DS.
