I decided to, for the first time on my 2016 Sport with about 12K miles, check the rear wheel play yesterday. There is only in one specific spot a tiny amount of play side to side, I estimate about a half millimeter or maybe less, at the outside of the wheel. The rest of the circumference has 0 play.
I wanted to check because on my last highway run on Tuesday, while accellerating at high speed (80 mph or so) it felt as if a vibration suddenly started in the drivetrain. But I could not tell if it was the bike or if maybe the road surface changed which can feel similar. Slowing back down to 70 the vibration disappeared. Will need to go back out and check again at high speed soon, but at this stage I don't think it would be the rear wheel bearing. More likely, if it is indeed something in the bike, the vibration damper that may have failed:

Then again, there has been some roughness in the drive over 80 mph before, same with a R1200RT I briefly owned earlier this year, that I was a bit disappointed by for such an autobahn cruiser, between 70 and 80 mph.
Don't mean to take this thread off-track but thought this may be relevant to some.
