The company was taken over by DMW in 1963 who continued production until they closed the company in 1965. Ambassador Motorcycles was reformed in late 2016. 
Founded by Irish motorcycle racer and 1920’s Brooklands star Kaye Don in 1946 as "U.S. Concessionaires Ltd.", the company was started to import American cars. Motorcycle development started with a 494 cc vertical twin JAP-engined prototype. In 1947 the small Villiers engines were introduced and proved successful so were used until 1964. Ambassador motorcycles were costly and did not sell well, but exports to Australia and New Zealand were successful.
