Ossa-based Bikes
- Ossa SPQ, OSSA Seurat Piron Queyrel. Produced in France in the 1970s, the SPQ was an air-cooled 250 cc road racing motorcycle with a light frame and an OSSA engine. The SPQ excelled in French hillclimbing and criterium races in the decade, but was no match for the Yamaha TD2 in circuit competition.
- Yankee 500, a large off-road motorcycle produced in Schenectady, New York by the Yankee Motor Company. The Yankee, also known as "Ossa Yankee", had a 500 cc air-cooled Ossa twin-cylinder two-stroke engine, designed by Eduard Giró.
- Ossa BYRA 1000, a 977 cc four-cylinder two-stroke air-cooled road racing motorcycle built in Barcelona by engineer Fernando Batlló. The motor was based on two Yankee engines. This bike took part in the 24 hours of Montjuich races in 1972 and 1973. Only one was built as a road racing prototype and another as a street bike. This bike survives at the Bassella Motorcycle Museum, Alt Urgell.
