I have a 2009 V with 2200 miles that I ride in NJ. I have a 2010 V with 500 miles I ride in WV. The 2009 V became smoother as it was broken in, and smoother yet after I put in synthetic oil (Amsoil) at 1200 miles. The 2010 has more vibration than the 2009 V, but also fewer miles. It is a little smoother now at 500 miles than it was when I first got it. So far, I don't see any evidence that the rubber engine mount is reducing vibration in the 10 V.
However, both bikes are a pleasure to ride. The vibration is not serious enough to bother me.
