The Royal Enfield Bullet was originally an overhead-valve single-cylinder four-stroke motorcycle made by Royal Enfield in Redditch, Worcestershire, now produced by Royal Enfield (India) at Chennai, Tamil Nadu, a company originally founded by Madras Motors to build Royal Enfield motorcycles under licence in India.
The Royal Enfield Bullet has the longest unchanged production run of any motorcycle having remained continuously in production since 1948.[1][2] The Bullet marque is even older, and has passed 75 years of continuous production.
The Royal Enfield and Bullet names derive from the British company which had been a subcontractor to Royal Small Arms Factory in Enfield, London.
