Sub Frame Correction
My neighbor purchased my '05 250 EXC 2T and flipped it over again. This time he broke the rearmost extension off the right side of the sub frame, the piece that supports the rear of the plastic fender. He bought the new fender pieces, took the sub frame off and had the broken piece welded back on for $45.
So I have seen one break. You have to work at it, though.
