Rightly or wrongly I designed the fender and fork guards to mount on my fork brace. The idea was style and I forgot all about cost. The price of the fender and guards is cheap enough but the brace cost kinda blew the deal.
Some guys have order all the parts and have been fine. Others found a way to mount the guards without the brace. The fender? That is locked into and formed around the brace. If you wanted the brace anyway (for racing or street) then the guards are no problem.
