Harley-Davidson 1925 989 cc IOE V-twin model “J” engine # 25JE7563
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 services and other government bodies.
The OHV inlet, side valve exhaust concept was used till 1930, when HD chose the full side valve engine concept.
HDs became famous for their power, comfort and reliability.
There is still magic in the name, just as it was many years ago!
