The motorcycle had a hybrid frame, partially tubular and partially stamped steel. The front suspension was of parallelogram type, with coil springs, and the rear suspension was of the plunger type. The motorcycle got a single-cylinder, 495-cc engine. The transmission gear box had 3 speeds, with foot pedal control. The drive was effected by the open chain. Motorcycles had two fuel tanks so that the smaller tank was intended for high-octane fuel in order to facilitate the cold start of the engine.
Beside the OHV version, this motorcycle was produced with an L-head engine that could develop 15 h.p. (as opposed to 20 h.p. for the OHV version). The second important difference was that the L-head model had a rigid rear suspension.
In 1942-43 around 3300 M/42 motorcycles were produced (3000 OHV units and 300 L-head units), and many of them were still in service in the Swedish and Danish army until the 1960-s.
