Lot 415: c.1930 Rudge 349cc Racing Motorcycle

Collectors' Motorcycles, Bonhams (16 October 2005)

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. This 350cc Rudge was prepared for vintage racing in the 1960s, being converted to foot change and fitted with a high-compression piston enabling it to run on alcohol fuel. We are advised that the machine was very successful and for a time was reputed to be the fastest vintage-era 350 in Scotland. Subsequently de-tuned for road use, it has not been used for 15 years and represents an opportunity for the dedicated enthusiast to acquire one of the 1930s’ most exciting sports bikes, ripe for restoration. Offered with Swansea V5.
