The Harley-Davidson Knucklehead, produced from 1936 to 1947, is a legendary motorcycle that holds a prominent place in motorcycle history. Its iconic name derives from the distinctive "knuckle" shape of its rocker arm covers, which were designed to provide increased oil capacity and better lubrication to the valve train. The Knucklehead engine was a significant advancement over its predecessor, the Flathead, featuring a 45-degree V-twin engine with overhead valves, a design that offered improved performance and efficiency. It was known for its smooth, powerful engine and robust construction, making it a popular choice for both touring and racing. The Knucklehead was also a significant departure from the previous models in terms of styling, incorporating a sleek and streamlined design that set the stage for future Harley-Davidson models. The 1947 Knucklehead, the final year of production for this iconic motorcycle, saw several refinements and updates. Notably, the engine received a slight increase in displacement to 74 cubic inches, resulting in slightly more power and torque. Other improvements included the introduction of a new carburetor design for smoother throttle response and a redesigned oil filter for improved lubrication. While the 1947 Knucklehead marked the end of an era, its legacy has endured. These motorcycles are highly sought after by collectors and enthusiasts, admired for their historical significance, powerful performance, and unique design. The 1947 Knucklehead continues to be a symbol of Harley-Davidson's commitment to quality craftsmanship and innovative engineering, solidifying its place as a cornerstone of motorcycle history.
