“Ridden on a by no means ideal stretch of highway, over a very carefully measured quarter of a mile, it was timed to do the distance in an average of 1/10th second over 9 seconds. A writer from MotorCycling magazine was treated to a demonstration at the Redditch works by development guru, Tony Wilson-Jones. He revealed how a simple swap to a high compression piston and up-gearing by one tooth could produce outstanding results: The 500’s engine, with a sporty four-valve cylinder head, had real performance too.

Available in 250, 350 and 500cc capacities, its design was both contemporary and classic, with beautiful lines and a top quality finish. September 1932 saw the introduction of what would become the world-famous Bullet. Of greater significance, however, was the introduction of dry sump lubrication and Royal Enfield’s renowned plunger oil pump arrangement, both of which were to remain constant features of their motorcycles for the next 78 years. In 1930 sloper engines were introduced, their cylinders and cylinder heads inclined forwards by 20 degrees. The Model 505, as it was known, cost £52 and was handsomely finished in “best black enamel” with the petrol tank painted beige with deep red panels. The magneto was located directly behind the engine and was chain driven by the inlet cam spindle. The 488cc two-port single was up with the times in design, with a double row caged bearing big end, an I-section steel con rod and an aluminium alloy piston. The next evolution came two years later when the company’s first 500cc OHV engine was showcased at the 1928 Olympia Show. In Frame: The 1927 Royal Enfield 500 Side Valve It performed “its duties with a pleasing absence of fuss.” Top gear “pulled down to 15 mph without snatch and in bottom gear it was found possible to travel appreciably slower than walking pace without slipping the clutch.” Costing just £52, with electric lighting an extra £7, the future looked bright for the Enfield big single.

The MotorCycle, Britain’s leading weekly motorcycle magazine, grabbed one, mounted a sidecar on it and put it to test. The Model 500 was powered by a 488cc side valve engine linked to a four speed gearbox by a hand change lever. The next step was to develop a big single: in late 1926 the company launched their first at the renowned Olympia Motor Cycle Show in London. That changed in the mid-1920s, first with the adoption of JAP (JA Prestwich) 350cc engines in 1924, then Enfield’s own 350cc engines in mid-1925. The middle ground, populated by many other manufacturers, was not addressed. After WWI, a two model policy was adopted large capacity 976cc V-twins and small capacity 225cc 2-strokes, a strategy which covered both ends of motorcyclists’ requirements, namely a powerful workhorse suited to hauling heavy sidecars, and a small capacity, lightweight and economical commuter. It was powered by a diminutive 1 1/2 hp single cylinder engine and small capacity singles were to remain the company’s motors of choice until November 1909 when its first V-Twin was unveiled. Royal Enfield’s first motorcycle went on sale in 1901. In Frame: A Royal Enfield 1934 LFV 500 Engine
