The widest spot on my 2017 US model is at the mirrors, measuring 40.5 inches as currently positioned. The hand guards are a little narrower, about 38 inches, and the bars themselves are another inch or two less than that. I've added Givi V37 side cases which are just slightly narrower than the mirrors. With mirrors turned in a little, you have clearance to squeeze through (very slowly and carefully).
But are you claustrophobic?
