Brough Superior motorcycles, sidecars, and motor cars were made by George Brough in his Brough Superior works on Haydn Road in Nottingham, England, from 1919 to 1940. The motorcycles were dubbed the "Rolls-Royce of Motorcycles" by H. D. Teague of The Motor Cycle newspaper. Approximately 3048 motorcycles were made in the 21 years of production; around a third of that production still exists. T. E. Lawrence owned eight of these motorcycles and died from injuries sustained when he crashed number seven; the eighth was on order. Moving forward to 2008, vintage motorcycle enthusiast Mark Upham acquired the rights to the Brough Superior name.

A motorcycle fork connects a motorcycle's front wheel and axle to its frame, typically via a yoke, also known as a triple clamp, which consists of an upper yoke joined to a lower yoke via a steering stem, a shaft that runs through the steering head, creating the steering axis. Most forks incorporate the front suspension and front brake, and allow the front wheel to rotate about the steering axis so that the bike may be steered. Most handlebars attach to the top clamp in various ways, while clip-on handlebars clamp to the fork tubes, either just above or just below the upper triple clamp.
