The 1912 Rudge Multi was one of the most innovative motorcycles of the early twentieth century. Powered by a competitive 499cc engine, the Multi stood apart not for its capacity but for its revolutionary approach to transmission. At a time when most motorcycles relied on fixed gearboxes or simple belt drives, Rudge introduced a manually controlled variable-ratio system that removed the need for a traditional gearbox altogether.
The system used a belt drive with variable-diameter pulleys featuring movable flanges. By opening one pulley while closing the other, the rider could alter the belt’s running position, effectively changing the gear ratio. Rudge promoted this arrangement as offering 21 usable forward ratios, giving the rider exceptional flexibility. This proved particularly advantageous when tackling steep gradients, making the Multi highly capable in real-world riding and competition. While not automatic in the modern sense, the design is widely regarded as an early forerunner of later variable transmission concepts.
The Rudge Multi marked a bold step in the company’s engineering philosophy and quickly earned a reputation for technical sophistication. Its significance was firmly established in competition when Howard R. Davies rode a Rudge Multi to victory in the 1912 Isle of Man Junior Tourist Trophy. This win transformed the Multi from an engineering curiosity into a proven performance machine, validating its innovative design under racing conditions.
Today, the 1912 Rudge Multi holds legendary status among collectors and historians. It is prized for both its mechanical ingenuity and its importance in motorcycling history, with several examples displayed in museums across the United Kingdom. At auction, surviving examples typically command £20,000 or more, with particularly well-documented or well-preserved machines achieving higher prices depending on condition and provenance.
The Rudge Multi’s success helped establish Rudge as a leader in advanced motorcycle engineering. Although later Rudge models would go on to achieve further racing glory, the 1912 Junior TT victory remains the defining competitive moment for the Multi itself, securing its place as one of the most significant motorcycles of its era.
The final nail in the 1912 Rudge Multi’s deep wound would come in the form of war, the likes of which would change the world beyond all recognition. Factories were to alter their primary purpose, luxury items deprioritised, and supply lines shortened, as vital supplies for the war effort took priority. Sadly World War 1 meant a requirement for surplus metals that could be used in the manufacturing of essential supplies to the front line. In a sad turn of events, this meant many Multi's were scrapped or stripped for parts. WW1 had altered manufacturing forever, effectively delivering a final, cruel blow to a true icon of British motorcycling heritage. And yet despite all of that, the Multi continued to roll off the production line up to 5 years after the end of WW1, with a total of at least 20 to 30 surviving examples worldwide today. Now that's one tough machine.
