The Aermacchi Monsone (also Aermacchi 125 Modelo M ) is a motorcycle that the Italian company Aeronautica Macchi manufactured from 1952 to 1954. "Monsone" means " monsoon " in German .
history
The Monsone was developed from the manufacturer's first motorized two-wheeler, the Cigno scooter , and introduced in 1952. It was considered a sports version of the Cigno. It differed from it in a slightly more highly compressed engine, a seat instead of the two bicycle saddles and, above all, a tank in front of the seat, which turned the Monsone into a motorcycle.
At the same time, the similarly structured two-cylinder model Bicilindrica appeared in 1954, the Monsone was discontinued without a successor.
technology
Engine and drive
The Monsone has an air-cooled single cylinder - two-stroke engine with nearly horizontal cylinder. On the left stump of the double-bearing crankshaft there is a multi-disc dry clutch via which the engine power is transmitted to a straight-toothed three-speed gearbox. The transmission is connected to the rear wheel by a machine chain.
The petrol / oil mixture 1:17 is fed to the engine via a round slide carburetor with a 17 mm passage from the tank under the saddle. The ignition spark comes from an ignition light magnet .
Frame and chassis
The Monsone has a tubular steel frame with lowered central tubes. Both wheels sit in sprung arms with friction shock absorbers. The engine and transmission are also attached to the front of the rear swing arm. The frame and fenders are always painted in red or black.
Wheels and brakes
The 17 ″ wheels are wire-spoke wheels and have half-hub drum brakes . The rear brake is operated via a foot lever on the left side of the engine and a linkage, the front with a cable from the handlebars.
