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 OHV inlet, side valve exhaust concept was used till 1930, when HD  chose the full sidevalve engine concept. 
Development of the machines also meant they gained weight: the 1915 model weighed 305 lb., the 1929 model came to 400lb. 
In the early twenties a 1212 cc version (bore x stroke 87.4×101.6mm)was brought out. 
With this model the machine weight grew from 366 lb in 1924 to 420 lb in 1929. 
HD’s became famous for their power, comfort and reliability. 
There is still magic in the name, just as it was 75 years ago!

This machine is restored to concours condition.
