Yes we have a 7/8 inch diameter stock bars. I'm not sure if everything will fit properly with those though. I'm looking at some awesome Renthal Street fighter bars. I drool over them -__-
It should 99% of metric bikes are 7/8" Ø... the only thing I had to do on my 650 Ninja was flip the banjo bolt for the brake fluid reservoir and drill a small hole for locating controls... which should be easier on this, as the 650 Ninja the fairings interfered on the change. More than likely you will need to drill a hole for the controls still though.
