History and technology
This motorcycle model was a sports version of the Ala Azzurra 250cc model . The classic single-cylinder four-stroke engine with almost horizontal cylinder was derived from that of the less successful Chimera . It delivers 16 hp (11.8 kW), in contrast to that of the Ala Azzurra 13.7 hp (10 kW), because he has a 24 mm Dell'Orto - carburetor instead of 22mm like the Ala Azzurra . The compression ratio has been increased and the valve cross-sections enlarged. The machine is equipped with a four-speed gearbox and hangs in a steel tube / sheet steel frame, another characteristic of the motorcycles made in Varese .
The style was new with a tank in an unusual shape and a hump in the area in front of the bench, a bench with retaining straps, a low handlebar and 17 "wheels. The manufacturer specifies a top speed of 140 km / h. The Ala Verde was much more appreciated by buyers, especially for its road holding, speed, fuel consumption and brakes. The shift lever, which tended to scrape on the asphalt when cornering, turned out to be weak points.
In 1963, in the third year of Harley-Davidson's involvement with Aermacchi, the company launched the second series of Ala Verde, which differed from the first series in various mechanical changes, e.g. B. more efficient lubrication, clutch with four instead of three discs, new electrics and reinforced front fork, as well as optical improvements such as modified handlebars, side covers and exhaust. A five-speed gearbox was now offered at an additional cost.
In 1967 the third series of Ala Verde came out. The single cylinder from Varese has been revised again; The tank (which, however, looked similar to the first version), the fenders, the seat, the headlight and the front fork were new. The wheels were enlarged to 18 ″, which reduced the risk of landing in bends.
In 1970 the fourth and final series of Ala Verde was presented. This year the tank shape, the electrics (including the controls) and the fenders changed. The engine now developed 18 hp (13.3 kW), the five-speed gearbox was standard and the clutch now had five discs. The front wheel was also changed; it was now 19 ″.
The production of the Ala Verde was stopped in July 1972. The role of the sports motorcycle in the Aermacchi range was taken over by the 350 TV .
