Harley-Davidson 1928 model J 989 cc IOE frame #28F1118 engine #28 J 5232
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.
Development of the machines also meant they gained weight: the 1915 model weighed 305 lb., the 1929 model came to 400lb.
An important innovation for the 1928 models was the fitting of a front wheel brake.
More than 15,000 V-twins were produced this year and slightly more than 5,000 singles.
This Model J is nicely restored.
