Book excerpt: The most famous of all British racing motorcycles, with an ancestry dating back to the very dawn of the internal combustion engine, the 'cammy' Norton is inseparable from the era of British domination in motorcycle racing. It is linked with the legendary heroes of the sport, Jimmie Guthrie, Harold Daniell, Geoff Duke, John Surtees, Mike Hailwood and the age when Britain had the world's finest motorcycle industry. This revised edition of the definitive history contains additional material and traces the design, development, the leading riders and tuners. It presents a superb collection of photographs, many previously unpublished. The Manx Norton covers not only the Manx itself, but also features boardroom battles, Norton's early history, record breaking, sidecars, Formula 3 cars, scrambling (motocross); the Domiracer; racing at Daytona and today's classic scene.
