It was in 1901 that a 20-year-old William S decided to draw a small engine with a capacity of 7.07 cc and it was intended to be used with a regular pedal-bicycle frame. It was over the next two years that one of the best friends of Harley, Arthur Davidson, worked on the motor-bicycle in their machine shop along with his brother, Walter Davidson. They tested their power-cycle, during which Harley and the Davidson brothers could climb the Milwaukee hills without having to peddle and it was just the starting point!
They started working on a bigger machine, which had a displacement of 24.75 cc and this goes down in history as the first proper design of a Harley Davidson. They also increased the size of the engine and improved it at multiple levels.
In 1906, these folks had their first factory on Chestnut Street; which is where the present-day headquarters of Harley Davidson is. In the first year of production, they produced 50 motorcycles and rest is history, on how successful Harley Davidson is today!
