Only a handful of motorcycles have been significant enough to change the direction of the sport of motorcycling--landmark bikes whose engineering and performance altered the public's expectations of what a motorcycle could be. This includes such machines as Triumph's Speed Twin, Vincent's Rapide, Harley-Davidson's Knucklehead, Norton's Commando, Honda's CB750, Kawasaki's Z-1, BMW's R905, Suzuki's GSX-R 750, Ducati's Desmoquattro 851 Superbike, and many others. Few people better understand the history and importance of these classic machines than Kevin Cameron, and fewer still have the ability to convey that information to a reader in the accessible and comprehensible manner that is Cameron's trademark style. This book presents the bikes in their historical context and explaining just what made these machines so special.
