I've only owned one bike that I did not like. My current 09 KLR650. I bought a 2000 model new at the end of 1999 and traded it for an SV650 six months later. I should have known better.
Suspension- crap: the forks twist to the point of bad stiction entering corners
engine- crap: lots of vibes with a great lack of power
Ergonomics- so so.
Totally uninspiring. I actually putt around at the speed limit most of the time.
