K5 accident likelihood of structural damage from rear ender?

[Shifu]

The swingarm is really a solid chunk and to bend it from the rear it would take a mighty wallop. But I would really be concerned about the rear rim. Daz's father bumped his Gen2 busa rolling out of garage. Bike just fall on the ground and you would think nothing of it. But when he turn the rear wheel while lubricating the chain (f&*ck, yea I know) the rim was all wobbly and beyond straightening. Interestingly it did not noticed anything while riding (and he is not a slouch ) Insurance replaced the wheel without fuss.
