5 speed gearbox, but never got off the drawing board. A few prototypes were made using the existing S32 engine, but the machine never went into production. WFM Osa In 1955, WFM designed 3 prototype scooters, all named after insects: Żuk (beetle), Bąk (bee) and Osa (wasp). There was resistance from the authorities towards what they viewed as a "ideologically hostile" product, and pre-production models of the Osa weren't produced until February 1959. The scooter used a 148 cc single-cylinder, two-stroke engine, designated S 06, which WFM had been supplying to SHL. The machine used 14 inch wheels. The machine went into full production as the Osa M50. In 1962 the Osa M52 was introduced. This was fitted with the 175 cc S 33 engine. Much of the production of the M52 was exported to India. Production of the M50 was stopped in 1963 and the M52 in 1965. Competitions WFM entered factory teams in a number of ISDT events between 1956 and 1963, including the 1959 17th International Tatra Rally, the 1960 XXXV Sześciodniówce FIM in Bad Aussee, Austria and the 1961 Scottish Sześciodniówce. Both 125 cc motorcyles and Osa scooters were used. Production 1951–1965 Motorcycles - 600,000 Scooters - 28,000 Engines - 250,000 units Resurrection At the beginning of the 21st century, a project was created to reactivate the WFM brand in cooperation with the Minsk Motovelo Motorbike and Bicycle Factory in Belarus. The originator of the project was Włodzimierz Gąsiorek, who owned the WFM trademark through the Motor Klub Wawer. The motorcycle was a modification of the Minsk Lider, and was available in 50 cc and 125 cc versions.
