Authenticity & Accuracy
This 1936 Knucklehead Straightleg Rigid Frame is produced according to original EL specifications and designed for serious pre-war restorations. The geometry, mounting points and overall construction follow documented 1936 factory dimensions to ensure period-correct fitment and authentic appearance.
This frame is intended for builders and restorers who require historically accurate foundations for early Knucklehead projects (1936–1937 EL models). Attention has been given to structural integrity, alignment and correct visual details characteristic of first-year Knucklehead production.
Cast components on this frame feature the original casting numbers as used by Harley-Davidson in period production — a detail we consider essential for any restoration that aims to be truly period-correct.
