The bike,2011, is clean and in good shape, most of my experience is with mx, not much on the road, I am 6 foot 210 pounds.
Agree with you about the shoulders, I can feel the effect cause a slight wobble over 80mph, until I duck under the little fairing.
Good to know about the tires, I have 40/60's that came with the bike on now, will change over to something more street oriented when they start to where out, as most of my riding will be street.
The thing about the bags is, as soon as I removed them it stopped. First I tried changing air pressure, with no change, then off with bags and that did it.
