I'm thinking of picking up a used SV650S.

Two things I'm unsure of since I haven't sat or ridden one.

Hows the vibrations at idle, city and highway riding?

Also, how much knee room is there on the S model? I'm 6'1"

Thanks for any feedback.

There are of course more vibrations than on an inline 4, but it's not that bad. I've done 140mph on mine (on the speedo) and it's ok http://www.gixxer.com/forums/images/graemlins/banana.gif IMO there's plenty of leg room on the S. I'm 5'11" and I even have rearsets (1.25" up and 1.25" back) http://www.gixxer.com/forums/images/graemlins/thumb.gif

I really dont have any noticeable vibration on mine. i rode gsxr 600 and noticed little difference.
just so you know i am also selling my sv650, if you are interested pm me.

It is so minor that you can't tell the difference from an I-4.
