The Knucklehead was Harleys first big twin with overhead valve (OHV) dry sump oil lubrication, oval Fat Bob tanks, and a cat's eye dash
It was produced from 1936 thru 1947 and likely saved the company from extinction
The Knucklehead showcased the recirculating oil system, which scavenged the used oil into an oil reservoir mounted to the rear of the engine for re use
Before the Knucklehead, Harleys ran total loss lubrication, where lubricating oil was only required to make a oneway trip ultimately being burned up, blown out, or dripped onto the drive chain
This extremely rare Knucklehead is a multiple AMCA show winner
