Royal Enfield

HISTORY:

Royal Enfield was the name under which the Enfield Cycle Company

made motorcycles, bicycles, lawnmowers and stationary engines. Their motto

"Made like a gun, goes like a bullet”. Use of the brand name Royal Enfield

was licensed by The Crown in 1890. The original Redditch, Worcestershire

based company was sold to Norton-Villiers-Triumph (NVT) in 1968.

Royal Enfield produced bicycles at its Redditch factory until it closed in

early 1967. The company's last new bicycle was the 'Revelation' small wheeler,

which was released in 1965. Production of motorcycles ceased in 1970 and the

company was dissolved in 1971. In 1956 Enfield of India started assembling

Bullet motorcycles under licence from UK components, and by 1962 was

manufacturing complete bikes. Enfield of India bought the rights to use the

Royal Enfield name in 1995.
