2019 Brough Superior Anniversary

After the initial introduction of the SS100, the Alpine Grand Sports, an SS100 with a full touring specification. was launched at the 1925 Motorcycle Show. In the same year Brough Superior produced a 110 mph (180 km/h) Pendine Racing Model (named after the Pendine Sands where Malcolm Campbell set a number of world speed records) with increased ground clearance. Every owner was encouraged by Brough to suggest their own ideas for developing the SS100, which meant that almost all his motorcycles were uniquely hand-built and the design continually evolving. The Sturmey-Archer gearbox was upgraded in 1929 for a three speed "super heavyweight" box to cope better with the 50 bhp (37 kW) produced by the JA Prestwich Industries (JAP) engine. In 1928 Brough introduced rear suspension and in 1934 the Alpine Grand Sports gained a 75 hp (56 kW) overhead valve JAP engine known as two of everything as it had two magnetos and two oil pumps. A foot gear-change was introduced in 1935 and a four-speed Norton gearbox in 1936. Development on all Brough Superiors was stopped during the Second World War, when the factory was turned over to war work.
