The Harley-Davidson Knucklehead, a motorcycle that defined an era, was produced from 1936 to 1947. The name "Knucklehead" comes from the distinctive outward appearance of the engine's rocker arms, which resemble knuckles. It was the first major redesign of the Harley-Davidson Flathead engine, introducing a number of innovative features that would become iconic for the brand. The Knucklehead featured a new overhead valve design, which provided increased power and efficiency compared to the older Flathead. This powerful engine was coupled with a more refined chassis, including a new frame and springer front fork. The Knucklehead quickly became the top-of-the-line Harley-Davidson motorcycle, offering riders an exhilarating and reliable experience. The 1942 Knucklehead, produced in the midst of World War II, was a significant model. While its production was impacted by the war effort, it still embodied the spirit of the Knucklehead. The 1942 model featured a distinctive "wartime" finish, with painted components instead of chrome, reflecting the scarcity of materials. Despite the wartime constraints, the 1942 Knucklehead remained a powerful and capable motorcycle, offering riders a sense of freedom and adventure. The popularity of this model continues today, with many enthusiasts seeking to restore and ride these historic machines. The 1942 Knucklehead stands as a testament to the enduring legacy of Harley-Davidson, a brand that has long been synonymous with American freedom and the open road. A complete service repair manual for this iconic motorcycle would be an invaluable resource for any owner seeking to maintain and restore their Knucklehead to its former glory.
