Polish-made scooter, Osa was produced in the Eastern European bloc. Design work started as early as 1955 with the first production examples leaving the factory in 1959. Production of M50s continued until 1962 when an improved version called Osa M52 appeared. Osa (wasp in Polish) has a number of interesting design features. For example, to gain access to the engine the entire body work can be lifted by pulling on the grab handles toward the rear of the scooter. Mounted on a pair of tubular sliders, the metal body lifts easily to reveal the entire powertrain,
making servicing a cinch. The Osa has uncharacteristically large tires for a scooter. Envisioned as a utilitarian vehicle, the Osa had to be able to cope with paved, as well as unpaved roads of rural Poland. By using 14" wheels Osa could easily traverse rough terrain. In fact, because of its outstanding suspension and large wheels, Osa was frequently entered in enduro-type ISDT competition events where it always did very well – winning a gold medal in the 1961 Welsh ISDT, and three silver medals in the Garmish Partenkirchen ISDT. The presented example of an early production M50 is a rare sight, even in its native Poland. Very few M50s exist today (most surviving Osas are M52 models), especially in riding condition. Except for the paint and a non-original petcock, this M50 appears as it did when it left the WFM factory in 1961.
