I have been using the HYDE style m shaped bars, upside down, the bars need to be about 30'' + wide for the master cylinder to clear the head light assembly, I had to move the braided line to the inner hole.The bars I have on now are a flat m bar, no offset up or down 29'' wide and the rubber boot just touches the fork leg, I was surpised how much difference a inch or two in width made the steering feel slower, also the lower bars were good on the open road but terrible on the wrists on long windy downhill sections.
