The Brough Superior SS100 was a sports motorcycle by the British manufacturer Brough Superior , which was built from 1924 to 1940. When it was first introduced, George Brough wanted the Brough Superior SS100 to be the fastest and best production motorcycle in the world. He also expressed this with a guaranteed top speed of 100 mph (~ 161 km / h). A total of 283 copies of the SS100 were built; today 131 machines are completely preserved.
History and technology
The predecessor model presented in 1923, the Brough Superior SS80, was offered with a guaranteed top speed of eighty miles an hour (hence the number 80 in the model name). This model became the basis for Bert Le Vack's racing motorcycle, who set a new speed record for motorcycles with 182.590 km / h on April 27, 1924 in Arpajon with a tuned Brough Superior (JTOR prototype) and improved it three times by 1929. The SS100 introduced in 1924 is based on Le Vack's racing machine. The KTOR JAP 8/45 engine (bore of 85.5 mm and stroke of 86 mm) was offered in the SS100 Alpine Grand Sports (AGS) model from 1925 to 1929 . It was equipped with a Bings or B & B carburetor and magneto ignition, and the motorcycle achieved a consumption of 50 mpg (5.6 liters / 100 km) with it; With a tank capacity of 17 liters, there was enough range for tours.
In addition to the touring model AGS, there was the sports model Pendine from 1926 to 1930 , which was fitted with the JTOR-JAP 8/50 engine for the first time in 1928 and had a "110-mile guarantee". In 1929 the AGS were also equipped with the JTOR 8/50 engine from JAP with a displacement of 996 cm³ (80 mm bore and 99 mm stroke), recognizable by the double exhaust system with fishtail silencer. In 1932 a 4-speed gearbox was offered that was operated by footshift, and in 1934 the JAP engine 8/75 was installed. Equipped with two Amal carburettors and two magneto ignition units, the "Two-of-Everything" engine was the most powerful series engine of its time. The guaranteed top speed was set at 110 mph with the 8/75 engine and 90 mph with the sidecar. The tire size of 28 inches was reduced to 26 (front) and 27 inches (rear) in 1934, so that the wheelbase was also slightly shortened. Almost identical to the Sager cushion fork by William S. Harley was the pushed short swing arm , which was used by Brough Superior under the name Castle fork.

In 1936, instead of the JAP engine, a Matchless engine was installed as standard : Of the Brough Superior SS100 Matchless - again with the 100-mile guarantee - another 102 examples were made by 1940, of which 68 are still preserved today.
The last world speed record for Brough Superior was set by Eric Fernihough on April 19, 1937 with a covered SS100 with a compressor in Gyón (Hungary) at 273.244 km / h.
In 2012 a rare Brough Superior SS100 from 1934 was auctioned for 309,000 euros at Bonhams .
Private driver
- TE Lawrence owned seven Brough Superior: a Mark I (1922), an SS80 (1923), an SS80 with sidecar (1924), and four SS100; a fifth SS100 was ordered but was not delivered. In 1925 he bought the first 100 models (SS100 and AGS) which, like all his motorcycles, he called "George" . Lawrence was a frequent driver; from 1922 to September 1926 he covered over 100,000 miles on a motorcycle. In 1929 he acquired another AGS ("George VI") and in 1932 an SS100; with this "George VII" (registration GW 2275 ) he had an accident.
- In 1927 Konrad Lorenz drove a scaled-down version of the SS100 with an OHV-680 engine in Vienna.
