Villiers manufactured a range of single and twin two-stroke engines (from 98 cc to 325 cc) for light motorcycle and vehicle manufacturers until the 1960s. In the early 1960s, the company was taken over by Manganese Bronze Holdings, and in 1966 together with AMC became Norton-Villiers, and in 1972 merged with the BSA group to become Norton-Villiers-Triumph, which eventually went into.
