The Early Years: 1903-1930s

The story begins in a small Milwaukee shed where William S. Harley and Arthur Davidson built their first motorized bicycle. This single-cylinder machine, though rudimentary, marked the birth of a legend.

The F-Head Era: 1910s-1920s

Harley-Davidson's F-head engines, with their intake-over-exhaust configuration, powered motorcycles through the teens and twenties. Models like the Model 7D and J-series established Harley-Davidson as a dominant force.
