knulehead/Panhead (1 jan 1936 ano – 31 dez 1965 ano)
Descrição:
In 1936, Harley introduces the overhead valve EL, a 61 cubic-inch engine with increased horsepower and uniquely shaped rocker boxes that earned the nickname Knucklehead.
Harley-Davidson adds new features to the 61 and 74 OHV V-twins including aluminum heads, hydraulic lifters, and one-piece chrome-plated rocker covers that resemble cake pans. The name Panhead was a perfect fit.
