Brough Superior
George Brough named his bikes Brough Superior to the displeasure of his motorcycle engineer father William Brough, thereby relegating William's bikes to be henceforth known as Inferior. George used his own frames and bought engines and various other parts to produce exciting, exclusive, and expensive bikes.
George's bikes did prove to be superior and not just against his father's bikes. In the 1920s and 1930s George racked wins and records. Located in Nottingham, England the firm was thought to produce some of the best bikes in the world. The Motor Cycle claimed they were essentially "the Rolls Royce of motorcycles", and Brough used this quote as a slogan in advertising - Rolls didn't object.
SS100
The most famous Brough was without a doubt the SS100. It was initially powered by a 980cc V-twin from JA Prestwich (JAP).
