Seeking a way to keep its factories fully occupied after The Great War, specialist steel maker Dunford & Elliott diversified into motorcycle manufacture, launching the 'Dunelt' in November 1919. The first Dunelt was unusual in being powered by a 499cc two-stroke single at a time when 350cc was considered the maximum capacity for such an engine, and even more so by virtue of its stepped piston, which was of larger diameter at the bottom than the top. On its way up, the piston drew 770cc of charge into the crankcase and on its way down forced it via the transfer ports into the 499cc cylinder, thereby achieving a measure of supercharging. The result was a relatively slow-revving engine (thanks to the weighty piston and enormous flywheel) that possessed phenomenal low-speed torque. Indeed, Harry confirms that this one 'pulls like a train'. By the end of the 1920s the original 499cc two-stroke model had gone and Dunelt turned to proprietary engines. The early 1930s was a tough time for relatively small manufacturers such as Dunelt, which ceased production at the end of 1935. Thoroughly restored by Harry, this rare Dunelt two-stroke is described as in generally excellent condition and comes with a quantity of photographs. We understand that a registration document has been applied for.
