These have an forks cross-section of size of the castle forks the near triple plates underneath the head stock and are tapered down to about half these dimensions at the bottom end.

There Castle forks have been far astern replications with rear legs machined from solid. These were, of course, very heavy. But motorcycle parts are there must be someone in this world of the castle forks who is making decent replicas for the Harley restorers. The motorcycle work back then was mostly straight forward conditioning of spindle bushes, but I now re-tube and manufacture forks and also re-tube and repair frames.
