Harley Davidson manufactured the knucklehead engine between 1936 and 1947.   The knucklehead came in 60 cubic inch (990 cc) and 74 cubic inch (1,200cc) variations able to produce 40 and 45 horsepower respectively.

Harley Davidson Knucklehead engines are distinguished in appearance from the rest of the engines by the head.   The Knucklehead was named after the knuckle-like valve covers look of an upside down cake pan on the top of the engine.   The chrome head of a knuckle head engine resembles the back of your hand.   The sculptural appearance of this engine has great appeal for those who love the look of power.

The Knucklehead engine was the first overhead valve engine made by Harley Davidson.   The Knucklehead was the heart of a boldly redesigned and reengineered cycle, the revolutionary Model E.   Harley Davidson's Knucklehead provided vastly increased horsepower and durability over previous designs. This engine is referred to the "61 OHV" in factory literature of the day and called the Sixty-one in every day circles.
