William S. Harley and Arthur Davidson developed the first prototype of a motorcycle in 1903. The engine was designed according to the system De Dion-Bouton, had a displacement of 167 cc and made about 2 ps (1.5 kw). Since Harley and Davidson were dissatisfied with the performance, in 1904, cubic capacity was increased to 405 cm³ at one of bore 76 mm and one stroke 89 mm.
