I bent the front rotor numerous times on my YZ and Rm,s you bend them back,they get weak and get bent easier after straightening them. A stock size rotor is strong enough, use honda pads they have the strongest braking power,a steel braded line helps on YZ,s also. Oversized rotors can get bent in ruts and from other bikes much easier. It,s a good idea to have a spare front rotor,when going racing. I bleed the brakes often,using the highest heat brake fluid.
