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.
