Harley- Davidson 1927 model JD 1200 cc IOE frame # W14152 engine #27 JD 8884
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.
For 1927, no more than 3561 model J machines were sold; the 1200 cc JD was much more in demand with 9691 units leaving the factory.
Not surprisingly perhaps, as the price difference between these models was a mere $10.
1927 was the fist year of the “wasted spark” distributorless ignition system using a circuit breaker and a single coil firing both spark plugs at once.
This machine has been part a museum collection for many years.
It has been excellently preserved .
A front brake has been fitted at some time in the past by a former owner; undoubtedly a sensible addition.
This JD comes complete with Corbin speedometer, full electric lighting and passenger seat.
