When it comes to legendary motorcycles, few are as celebrated as the Harley-Davidson Knucklehead. Produced from 1936 to 1947, the Knucklehead marked a turning point in Harley history with its revolutionary overhead-valve engine design and distinctive styling.

At Heather’s Leathers, we honor that same tradition of craftsmanship with handmade leather saddlebags, tool bags, and riding accessories designed for riders who value both heritage and quality.

The Birth of the Knucklehead

In 1936, Harley-Davidson introduced the EL model, which would later earn the nickname “Knucklehead” because of the shape of its rocker boxes. This new design replaced the flathead engines Harley had relied on for years and set a new standard for power and performance.

The Knucklehead wasn’t just a new motorcycle—it was a statement of engineering progress and American resilience during a time when the country was climbing out of the Great Depression.

Popularity and Cultural Impact

The Knucklehead quickly became a favorite among riders looking for performance and durability. It also attracted attention from custom builders after World War II, who used the model as a foundation for early choppers and bobbers.

Today, the Knucklehead is considered one of the most collectible Harleys ever made, with restored models commanding premium prices at auctions.

The End of an Era

In 1948, Harley-Davidson retired the Knucklehead in favor of the Panhead, which offered further improvements in reliability and performance. But the Knucklehead’s legacy lives on as a symbol of innovation and timeless design.
