Strange, I have asked around and no one in the UK either has a problem or knows they have a problem. Definitely seen the photos of swingarms being rubbed by the Road 5 on US sites, apparently they are a very wide tyre for a 190 - over 200mm.
Not sure why, but it seemed to be on 2017 models onward having the problem - interesting that Michelin don't actually recommend a tyre for the K16 2017 onward anymore on their UK site when last time I checked they had both the PR4 and R5 in GT sizes as fitment?
