Those forks are always different diameters along the tube. There is a good engineering principle of that type of design but there were expensive to make.
Also Honda changed the size of the tubes a couple of times so you may need to check for a different set of covers. I am away at the moment so cannot check any details for you. Back home on 28th March.
