Swingarm failure - torque arm mounting point

[MC680x0]

I would actually question the need to tighten the torque arm to the extent it wouldn't adjust with the caliper bracket rotation when moving the wheel back or forward.  Afterall as already mentioned the bar is only to stop the caliper bracket from spinning. Obviously not too loose, just enough that with a bit of effort it can be lifted and lowered.

agreed! who said to tighten it like that anyway? that sounds - to me - what caused the problem in the first place
