I never "noticed" vibration so, I went out today to observe rpms/vibration. On my 2013 650, vibrations seem to max out at around 3000rpm and smooth out from there. If I place my feet firmly on the front floorboards, it seems to be more noticable. Anyway, to call what I feel, "vibration" is somewhat subjective. I had to pay attention in order to make a comment in this thread.
