Royal Enfield Interceptor/Continental 650 damper rod tool
To allow removal of the damper rod, a specialist tool is required to stop it spinning while you undo the bolt at the bottom of the fork. This takes a 1/2" drive extension and fits in the socket at the top of the damper rod.
Tips: Don't use an impact gun on the bolt at the bottom as it'll round the socket for the extension bar. I ended up using epoxy in the socket to ensure it held together, and it worked a treat!
