This revolutionary engine, displacing 996cc, was capable of producing an impressive 30 horsepower, making the M Series one of the fastest motorcycles of its time. The engine's power was transmitted through a four-speed gearbox and chain drive, propelling the M Series to a top speed exceeding 80 mph. The M Series was also notable for its advanced suspension system, consisting of telescopic forks in the front and a rigid rear end with spring-assisted rear suspension.
