Ok, i started to jump in then didn't, now i am. you recently posted a pic of your riser setup and the first thing i thought was "that setup cannot be structurally sound". some part will fail as you shift forward under severe braking. you have a ton of leverage at your handlebar grips that would result in failure of something. to me, it looks like the anchor locations would be weak points and no cross-bracing will change that. in fact, adding add'l weight would make it easier to snap off your bolts or risers.
i'm NOT criticizing your fitment choice but just wanted to point out what seems to me a huge safety concern.
just sayin'........
