Brett, yes it is, I would replace the top triple-clamp because the top dia. is larger and they are quite thin to start. Some guys just bore them out. you need to shim the bottom clamp (no trouble).
My preference is to fix the standard SS fork (if it's adjustable) The reason being, it can be made to work better than the stock Superbike fork and has the same potential as the Superbike fork with the exception of the nitride coating (if app.) and the Superbike fork has a little better rebound adjuster system. The Superbike fork needs to be resprung in most cases anyhow.
No doubt, stock to stock, the Superbike fork works WAY better. The reason is that the SS has CRAP cartridge internals. By replacing those and springing correctly, your golden.
The Superbike forks can be had for a low cost on Ebay. That's a good thing.
