The Knucklehead Company

Founded in 1977 in Wisconsin Rapids, Wisconsin, the Knucklehead Company was founded by a group of enthusiastic fans of Harley-Davidson® overhead valve motorcycles (i.e. Knuckleheads) produced between 1936 and 1947. Membership in the club requires ownership of a running bike from that era. The group aims to perpetuate the spirit of motorcycle club camaraderie that flourished in the 1940’s. The club has grown in membership over the past decades, and 23 years ago, an annual “reunion” was created to gather members – past and present – to celebrate the club’s history. The Company operates under the mantra: “Ride ‘em! Don’t hide ‘em!
