Motorcycle technology lagged far behind automotive technology since the earliest days of the internal-combustion engine. All that changed in 1936 when Harley-Davidson introduced the Model EL. For the first time ever, a company was manufacturing a high-performance overhead-valve engine for the masses.
And what an engine it was — in addition to bringing state-of-the-art technology to the motorcycling world — a work of art. Because of the shape of its rocker covers, the engine was given a nickname to match its looks: the Knucklehead. The technology used in this engine was so advanced that it laid the foundation for every future Harley-Davidson motorcycle, including the current models built in the 21st century. To this day every cruiser style motorcycle still adheres to the shape of that original Knucklehead.
Harley-Davidson Knucklehead: Eighty Years tells the entire Knucklehead story, from the very first overhead-valve V-twin Harley produced for the public through the post-war models, continuing right up until today, when aftermarket manufacturers reproduce complete Knucklehead crate engines because of its continuing popularity.
Greg Field has written a number of books on the subject of motorcycles, including several volumes dealing with Harley-Davidson, including Harley-Davidson Knucklehead, Harley-Davidson Panhead, Harley-Davidson Century, Harley-Davidson Evolution Motorcycles, Harley-Davidson Softail, Original Harley-Davidson Knucklehead, and Original Harley-Davidson Panhead. Most recently he contributed several chapters to Harley-Davidson Motorcycles: A Complete History.
