I am having a tough time with my front disc brake. I have bent 3 of them in the past 4 months! I have never bent a front disc on any of my previous bikes. So, is the floating disc design flawed, or weaker than the solid discs? Or, have I just had some bad luck? Also, has anyone ever switched to a solid disc? Please let me know what you think. ALSO, I would think a front disc guard would help? Does anyone know who makes one for the WR450? I think Devol makes a metal one. Maybe Acerbis makes a plastic one? Thanks.
