As Indian's premier model and one of the most desirable bikes among today's collectors, the Four represents the manufacturer's departure from the big twin motorcycles that dominated the prewar marketplace. Fast, expensive, and comfortable, the Four was an icon of affluence and performance during its 15-year production span from 1927 to 1942. This color history makes extensive use of all-new color photography of restored Fours, along with black-and-white archival shots, to chronicle the design, evolution, and production of this much-revered motorcycle.
