The Thor motorcycle, prominently displayed with its sidecar, represents a significant marque from the early era of American motorcycling. Manufactured by the Aurora Automatic Machinery Company of Aurora, Illinois, Thor motorcycles were produced from approximately 1907 until the early 1920s. Known for their robust engines and innovative designs, Thor initially supplied powerplants to other manufacturers, including Indian, before building complete motorcycles, establishing themselves as a reputable name in the burgeoning industry. The inclusion of a sidecar indicates the growing utility and leisure potential of motorcycles for carrying passengers or equipment.
