The Cyclery IOE Forks 1925-1929

This reproduction parallelogram spring fork is designed for early Harley-Davidson IOE (Inlet-Over-Exhaust) models 1925-1929. The fork follows the classic leading-link design, in which the front wheel axle is positioned ahead of the rocker pivot. Harley-Davidson used this design for more than two decades, and it proved so successful that it was later adopted by other manufacturers, including Brough Superior, where it became known as the “Castle Fork.”

The fork is supplied fully pre-assembled, including all inner and outer springs, rockers, and top caps. It represents the later version of this fork design with both inner and outer springs. The fork is supplied raw and uncoated, allowing the surface finish to be matched to the condition or finish of the other motorcycle components.
