These authentic reproductions of Harley-Davidson rigid frames provide a high-quality base for replacement frames or custom builds in chopper and bobber style. Made from robust steel and spheroidal graphite cast iron, the surfaces remain bare, ensuring maximum flexibility for painting, powder coating, or custom modifications.
The frames precisely match the dimensions and design features of the historical Harley-Davidson factory frames. Authentic cast parts with original numbers and markings, as used by the factory at the time, highlight the high level of detail and historical accuracy.
Technical features:
- Pressed-in seat post bushing for precise saddle mounting
- Precisely machined bushings for the brake shaft in the cross tube
- Year-typical toolbox mounting
These replacement frames allow for precise assembly and long-lasting operational reliability, ideal for faithful restorations or period-correct custom builds.
Please check permission to use them as replacements for original frames with your local authorities.
