We've installed several of the Shift-Tech units, I can only recall one being crashed at the track (low side into the grass) and it turned out fine, just some scuffs on the outer edge. The big risk is in a flip-over crash if the subframe takes a hard hit from the side or top, logic would dictate it's going to break, and that's an expensive replacement. I think it's a great product, looks really trick, although it's really not much lighter than running the Motoholders aluminum subframe and standard fiberglass race tail, 1.8 lbs. lighter is all. I was going to put one on my bike until I weighted it and decided the crashability of the standard setup was worth the 1.8 lbs.
