The full potential of Rudge's four-valves-per-cylinder design was slow to emerge, but in 1928 Graham Walker's works 500 became the first motorcycle to win a road race - the Ulster Grand Prix - at an average speed in excess of 80mph, a feat which led to the introduction of the legendary 'Ulster' sports model. Early engines deployed parallel valves in a pent-roof combustion chamber, then in 1930 a trio of 350s appeared at the Isle of Man with radially-disposed valves, the new arrangement demonstrating its superiority when the Rudges finished 1,2,3 in the Junior TT. The next move was to produce a 'head for the 500 featuring parallel inlet valves and radial exhausts, the chief advantage of which was reduced complication. This 'semi-radial' arrangement debuted on the 1931 works bikes, and in 1933 first appeared on the Ulster and TT Replica models, the only road-going Rudges to use it. Believed to be an Ulster, this example has the semi-radial valvegear and bronze 'head typical of the model. The combination of rear magneto and front dynamo suggests a manufacturing date of around 1934-1936. Partly dismantled and incomplete, the machine has been in storage for some considerable time. Offered for restoration and sold strictly as viewed, it represents an opportunity for the dedicated enthusiast to acquire one of the 1930s' most exciting sports bikes, ripe for restoration and at a bargain price. No reserve.
