Just wondering if anyone knows if the 650R is much smoother motor wise then a KTM 640? From research I found that the KTM's can vibrate so much that it stops some from purchasing one but then others insist they would not even weigh that in as a factor when purchasing! Maybe those are the real pu$$ies that it bothers more, I don't know?? The degree of vibration varies among the same machines too and on some it begins to disappear as they get more miles on. Now I'm talking purely riding on the street because I think you would feel it less off road and the bike (my bike anyway) would be on the street 90% of the time. Anyone ever ride or own both?
