This sporty overhead-valve Royal Enfield is in great shape.Royal Enfield’s origins can be traced back to a small light engineering firm – George Townsend & Company – founded in Redditch, Worcestershire, in mid-Victorian times.

By 1904 the firm was concentrating on car production, resuming motorcycle manufacture in 1910 with a v-twin Motosacoche-powered lightweight which was followed by the famous JAP v-twin-engined 7hp sidecar outfit for 1912. Enfield’s first 350cc single appeared in 1924 in overhead-valve and sidevalve versions, both of which used engines supplied by J A Prestwich.
The JAP engine gave way to one of Royal Enfield’s own manufacture for 1925, and in 1927 the firm introduced its first 500cc (3½hp) model, which used the 1,000cc v-twin’s 85.5x85mm bore/stroke dimensions for an actual capacity of 488cc.
