Description:
Brough Superior “The Rolls-Royce of Motorcycles” was synonymous with high performance, engineering excellence and quality of finish. That such a formidable reputation was forged by a motorcycle constructed almost entirely from bought-in components says much for the publicity skills of George Brough.
Introduced in 1922, the JAP-powered SS80 achieved instant fame when a racing version ridden by George became the first side valve-engined machine to lap Brooklands at over 100mph. With the new SS80's performance threatening to put their overhead-valve MkI in the shade, it was decided to completely redesign the latter.
The result was the legendary SS100. First shown to the public in 1924, the SS100 employed an entirely new overhead-valve 980cc JAP v-twin engine. Each machine came with a written guarantee that it had been timed at over 100mph for a quarter of a mile - a staggering achievement at a time when very few road vehicles of any sort could reach three-figure speeds.
With this level of performance available in road trim, it was only to be expected that the SS100 would make an impact on the race track, particularly the ultra-fast Brooklands oval, and the exploits of Brough Superior riders - among them Le Vack, Temple, Baragwanath, Fernihough and Pope - did much to burnish the marque's image. When Brooklands closed forever at the outbreak of WW2, Noel Pope's Brough Superior held the sidecar and solo lap records, the latter at an average speed of 124.51mph. Brough had entered the 1930s with an entirely JAP-powered range, and then in 1936 the SS100 was redesigned with an engine built by Associated Motor Cycles, in which form it continued until production ceased in 1939.
