Harley-Davidson 1919 model “F” 989 cc IOE V-twin engine # L19A5048
It took 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 was marketed in 1915.
This sturdy 989 cc (84x89mm) machine became a popular choice for motorcycle buyers all over the world, private enthusiasts as well as police forces, postal sevices and other government bodies.
The twin could be ordered with magneto ignition (“F”) or battery and coil ignition (“J”).
The engine delivered 17 HP @ approx. 3,200 rpm .For model year 1919 only minor changes were made, notably to the clutch and the handlebars, that were 2 ½ inch wider than earlier models.
Some 12,600 “F” machines were manufactured, 7,500 of them were meant for U.S. army use.
This impressive vintage machine has been restored with care and runs well.
