Warszawska Fabryka Motocykli (), commonly known by its initials WFM, is a defunct Polish motorcycle manufacturer. The motorcycles were manufactured in a factory located at 25 Ulica Mińska in the Warsaw district of Grochów. History The Warszawskich Zakładów Naprawy Samochodów () was established in 1947 by the amalgamation of the state-run Zakłady Urządzeń Transportowego No. 2 () and the Państwowe Zakłady Samochodowych No. 2 (). Amongst other activities, the workshop produced SHL M04 motorcycles for SHL from pre-war spares from Huta Ludwików and DKW engines. Later the engine designed for the Sokół 125 cc was used. The factory turned exclusively to motorcycle production in 1951 and the name was changed to Warszawska Fabryka Motocykli (WFM). The first motorcycles were delivered in 1952. Initially they produced 125 cc motorcycles for Wytwórni Sprzętu Komunikacyjnego of Psie Pole and SHL of Kielce. From 1955, WFM produced their own branded motorcycles and scooters and also supplied engines and components to other motorcycle manufacturers. Wacław Laskowski was the factory director for many years. On 1 January 1965, the WFM plant was merged with the neighbouring Polish Optical Works (PZO) and production of motorcycles was gradually phased out. The WFM machinery was taken over by PZO, who continued to produce engines and spare parts. Models Initial production was manufacturing the M04 for SHL, 27,000 machines were built between 1952 and June 1954. This model was superseded by the SHL M05, which had telescopic forks. 12,500 units of the M05 were built. WFM M06 The 1955 M06 was the first model branded as a WFM. It was a development of the SHL M05 and used the same 123 cc S-01 engine. The cycle parts were copied from the SHL M05 model, which had swinging arm rear suspension. An export model was produced with a battery, electric horn and chromed wheel rims. The domestic model received these refinements in 1957. Upgrades to the carburettor and cylinder head were made in 1958. A new more powerful engine, the S-34, was fitted in 1963. By the time production ended in March 1966, around 600,000 motorcycles of this model had been produced. WFM M16 Tarpan A successor for the M06 was planned in 1962. It was to be a new design and able to compete with machines from Jawa and MZ. The machine had a spine frame and leading link forks. A new 175 cc engine was designed which featured a
