I think i have these on my drz!! Last fall i bought some fancy moose bars. I think they had just come out. I got them from the zuki shop. I was looking for some taller bars they were there so i bought'em. I got moose bark busters on 'em now so it took out some of the flex. I don't have many rides on them and aren't super aggressive to begin with. I try like hell to avoid spectacular wipe outs that test bar strength. They seem to work ok, The grips are still on'em and when i push pull on them the front wheel generally goes where i want it to. They make my bike look cool! although i think the moose plastic handgaurd plastic is kinda thin!! Sorry dude, don't have enough time on them to give you a worth while report!!
