Like I said, I have the Dunlop T900 90/80 in front, It rubs a little on the inside of the fender, but not enough to damage the tire or the fender. as for the fork brace, I didn't have to change anything. I have the Racing Boy fork brace, no problems, but i did move it about 1/4 inch from the top of the fender just so the two piece's don't touch
