Brough Superior
1000 SS 100 Alpine GS – 1925
The Rolls Royce of motorcycles
The quality of
Brough Superior bikes was so celebrated that the company's machines were often
called the "Rolls-Royce of Motorcycles”. Only about 3000 Broughs were
built during the company's 1919 to 1940 lifespan.
Guaranteed Good for 100 mph
The SS 100, launched in November 1924, was based on a record-breaking bike
developed by the great rider Bert Le Vack. The SS 100 had set a new world speed
record of 113 mph at Arpajon, France, that year. Each SS 100 was guaranteed to
have hit at least 100 mph on the Brooklands track. Each SS 100 was assembled,
track-tested, dismantled, given five coats of enamel plus nickel-on copper
plated side panels for its saddle tank and lined-out in gold leaf before being
shipped.
Outstanding Roadholding
The SS 100 was the first Brough to be fitted with the famous
"Castle" forks developed by Le Vack and "Oily" Karslake,
which gave it outstanding roadholding. Among the company's most devoted
customers was Colonel T.E. Lawrence - Lawrence of Arabia - who was a personal
friend of George Brough and owned several Brough Superiors over a ten-year
period. He was killed while riding one of them in 1935, swerving to avoid a boy
cyclist. And an enthusiastic motorcyclist named William Lyons used the "SS
100" designation with Brough's blessing when he created the Jaguar
carmaker in the Thirties.
