Harley-Davidson: words that evoke the open American road and the “Made in America” tradition like no others. The sweeping chopper handlebars, the distinctive throaty low speed rumble of the engine and the unmistakable logo are all recognized the world over. This book expertly ties together the mechanical evolution of Harley's engines – from the earliest motorized pedal bicycles to the iconic heavyweight twin cylinder V-engines we know and love today – and the social history of the brand's phenomenal rise in the twentieth century, as innovative survivor of the Great Depression, supplier of the military during both World Wars and enduring symbol of freedom and rebellion. It is fully illustrated with pictures of the bikes and those who have ridden them as well as examples of Harley-Davidson's distinctive design aesthetic in advertising and collectibles.
