It takes the Harley-Davidson Co. about 12 years to develop their motorcycles from a single cylinder belt driven single 3 HP machine to the 45 degree V-twin with 3-speed countershaft gearbox that is marketed in 1915. This sturdy 989 cc (84x89mm) machine becomes a popular choice for motorcycle buyers all over the world, private enthusiasts as well as police forces, postal services and other government bodies. The twin can be ordered with magneto ignition (“F”) or battery and coil ignition (“J”). The engine delivers 17 HP @ approx. 3,200 rpm. The OHV inlet, side valve exhaust concept is used till 1930, when HD chooses the full side valve engine concept for all their V-twins. In 1920 a new factory building is completed; this makes HD the largest motorcycle factory in the world with 2,400 employees and established dealerships in 67 countries. Harley-Davidsons are fast becoming famous for their power, comfort and reliability.
This 1921 Harley Davidson model “F” is equipped with a French “Union” headlight in which cleverly a batter-powered LED lighting system has been installed. Accessories comprise a rear wheel driven Jones speedometer and a “Claxon” push horn. The machine has been technically restored but due to circumstances the machine still awaits a finishing touch. She comes with Dutch registration papers.
