When this was a new model, back in 07, Kawasaki released quite a bit of info on the design approach that was taken. I'm pretty sure there was mention made of a reinforced subframe, but my wife tells me my memory is not the steel trap it once was, so who knows? Nevertheless, the trellis components are, as you say, structural, and it would stand to reason that this assembly would be stronger than just tubing cantilevered out the back of the bike (as on the er6 models).
