The Royal Enfield Bullet was originally a British overhead valve single cylinder four-stroke motorcycle made by Royal Enfield in Redditch, Worcestershire, now produced by Royal Enfield Motors, the successor to the British company, at Chennai, Tamil Nadu, in India. The Royal Enfield Bullet has the longest production run of any motorcycle having remained continuously in production since 1948. The Bullet marque is even older, and has passed 75 years of continuous production. The Royal Enfield and Bullet names derive from the company's links with the Royal Small Arms Factory in Enfield, London.
The Bullet has evolved from a four-valve engine with exposed valve-gear to the latest all-alloy unit construction engine with electronic fuel-injection.
Introduced in 1931 as a four-stroke single cylinder motorcycle, this model was the first to feature the Bullet name. It differed in a number of ways from its successors (which are now familiar): it had an inclined engine with exposed valve gear featuring four valves per cylinder with 350 cc and 500 cc options. In 1933, a 250 cc option was also added to the range. Its frame was also considerably different, having centre-spring girder front forks, being among a new range of models from Royal Enfield that featured them, along with a saddle-type fuel tank. However, common to motorcycles of this period, it had a rigid rear-end, necessitating a 'sprung' seat for the rider, which resulted in the iconic look of the motorcycle that is much replicated today, even though the sprung seat is unnecessary in modern models.
After competition success the 350 cc Royal Enfield Bullet was bought by the British Army for dispatch riders and 3,000 were also supplied to the RAF during the Second World War.
This model refreshed Royal Enfield's model line-up for 1939. It differed in cosmetic details, as well as in having two rocker boxes, which resulted in higher volumetric efficiency for the engine. The basic design with front girder forks was retained.
