The 1946 Harley-Davidson EL 'Knucklehead' is a sublime example of the classically American motorcycle. The EL, a completely new motorcycle design in 1936 from the frame to the engine to the gearbox and styling, was the first Harley with a duplex-tube frame and The Motor Company's first OHV V-Twin street bike. Featuring Harley's first recirculating oil system and a 4 speed gearbox added up to a beautiful and streamlined package the company has yet to better. The teardrop fuel tanks, a dash-mounted speedometer, and imaginative fenders - along with the styling cues - make it a piece of rolling art. By 1946, the OHV motor was dependable and ultimately became the single most sought-after of all Harley Davidson models.
