Harley-Davidson 1928 model “28BA” 346cc OHV single engine# 28BA 5301
The 35 ci singles were discontinued at the end of the model year 1918.
The company tried to win customers in the 600cc class with the flat twin model W Sport Twin that was produced from 1919 up to including 1923.
Sales were relatively modest, but it was clear that especially in the European markets a small-capacity HD would be a selling point, if only to act as a “starter model”.
In 1926 some 350 cc class models were brought out.
The side valve models 26A and B (the B had an electrical lighting system) were good sellers: more than 7000 machines found a home in the first year of production.
The OHV “ AA” ( magneto) and “BA” ( battery and coil) versions were rather exotic machines mainly meant for competition use.
New for 1928 were magnesium-alloy piston, lightened flywheels and connecting rod and internally expanding drum front brake.
The last “BA” was produced in 1931, in all some 2,100 were made.
This machine is an interesting restoration project.
