Just measured my SW Motech crash bars, the high ones, not the lower Suzuki fitment ones. They come to 58-60cm, it's awkard to measure. I'd say they are no more than 5-6cm wider than the fairings. SW Motech bars are a good diametre (more than an inch?) and are some of the wider bars out there, I'd say. My rear pillion footpegs are 1-2cm wider than the crash bars when they are folded up so if you can get the rear pegs in there you should be fine with just about any crash bars.
