I have the Rethal 7/8" aluminum bars. They are great.. but i can't seem to find any hand gaurds that fit them. The diameter of the hole through the bars is smaller than the typical bars, so all the gaurds are too large to fit in the end. ... anybody know of any that fit.?....
Any local shop should be able to help you out too.
I have the Enduro Engineering handguards and they came with the hardware for plain steel bars and for the 7/8" style Renthals. I use them with my Renthals and they work fine.
