Harley-Davidson’s Knucklehead is one of the rarest, most expensive and most revered vintage powerplants still being used by builders today. Because of the simplicity, style, and heritage of the bike, it’s still the first choice for many customizers that can afford one. And, of course, Born-Free doesn’t just have tons of them chopped up and out on display, no, it gave away an epic barn find as well.
Knuckleheads were made from 1936–1947, straight through the middle of WWII, which meant that supplies needed to build motorcycles were also needed for the war effort. Throughout these years, there were countless small changes and many single-year-only parts, which makes them not only hard to find but hard to know and understand as well. For example, the bikes were made with several different configurations based on what part of 1936 it was manufactured. I’m no Knucklestorian, but I can appreciate the story of these bikes, their beautiful design, and what each of their riders has done to make their bike their own.
