if you have the older bars, just attach em on the side, or be cheap and just ziptie the controls to the riser, seen it done a time or two.
i think the biggest benefit i see is that i dont turn my high beams and handwarmers on all the time without. and you help lessen the risk of snapping the buttons off, i broke my reverse button off my old sled, still had the button mount, it was just really hard to push.
