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.
