Harley Davidson Evolution

The history of the Harley-Davidson motorcycle began in Milwaukee in 1903. In Milwaukee, Bill Harley and Arthur Walter Davidson developed a one-cylinder motorcycle. Around the turn of the century the gasoline engine was developed and the one-cylinder motor was introduced. The bike was built to be a racer, with a 3-1/8 inch bore and 3-1/2 inch stroke. The factory in which they worked was a 10 x 15-foot wooden shed with the words "Harley-Davidson Motor Company" crudely scrawled on the door. Arthur's brother Walter later joins their efforts. Work immediately began on a new and improved second-generation machine. This first "real" Harley-Davidson motorcycle had a bigger engine of 24.74 cubic inches (405 cc) with 9.75 inches (25 cm) flywheels weighing 28 lb (13 kg). The machine's advanced loop-frame pattern was similar to the 1903 Milwaukee Merkel motorcycle . The bigger engine and loop-frame design took it out of the motorized-bicycle category and would help define what a modern motorcycle should contain in the years to come. The boys also received help with their bigger engine from outboard motor pioneer Ole Evinrude who was then building gas engines of his own design for automotive use on Milwaukee's Lake Street.
