Suspecting ball joints, I rode it to a local dealer yesterday and we checked as you describe.
I pulled down on the back of the bike (I'm a certified counter weight) and the chief tech checked the front.
He popped up and said , Yep...front to back clunk / movement. We switched places and I felt it too...He lacks the necessary counterweight certification ( he's not mmmm..stocky, like me) so I only tried for a couple of seconds. It was pretty cold out, I was bundled up in a winter suit, and I didn't know quite how to position myself, but I felt it.
Can't say I ever noticed any slow speed weave, except maybe when coming to a stop. A couple times the bike seemed to veer a bit just b-4 stopping. Thought it was just me, out of practice, and unfamiliar with a new bike.
I definitely notice a strange turn in feel to the bike.
Had the bike at the same dealer for oil, final drive fluid, LED brakes lights and such a couple weeks back.
At that time,I asked the tech if he felt that the bike had a strange feel at turn in during his brief, after service test ride. He replied, yes, thought maybe it was just him though.
While we had it in the air yesterday, tech checked the dampener, seemed to function fine. No resistance to slow input, stiffened up with fast input.
Only ~ 9,000 miles.... on this bike.
