Ossa was a motorcycle manufacturer based in Catalonia, Spain which was active from 1924 to 1982. Founded by Manuel Giró, an industrialist from Barcelona. Ossa was best known for lightweight two-stroke-engined bikes used in observed trials, motocross and enduro. The company was known originally as Orpheo Sincronic Sociedad Anónima (O.S.S.A.) and was later renamed Maquinaria Cinematográfica, S.A.. In 2010, the Ossa brand was reborn when the trademark was purchased and a new company began producing motorcycles.
In 2010, a group of Spanish businessmen purchased the rights to the Ossa trademark and began producing Ossa branded motorcycles once again. The new firm produces trials and enduro models. The factory team competed in the 2011 FIM Trials world championship, with factory sponsored rider Jeroni Fajardo finishing the season in fifth place.[9
