I will chime in my two cents since I have pretty much exclusively been riding sport bikes for about 13 years before I bought the Versys and just this weekend went on a nice twisty road with it.
On a smooth road the Versys 1000 actually does very well, you can feel its long suspension but its surprising how willing it is to lean over and gobble up corners. It doesnt seem to like trail braking much but I feel like I could pretty easily "push" the average group of sport bike guys up in the twisties with out being too much of a maniac.
This bike does not handle mid corner bumps well at all. Now yes, I need to do some suspension adjustment (which Ive tinkered, but havent solved this issue yet) but there was a few times when Ive hit a dip or small bump mid corner that sends the long travel suspension into absolute butt-puckering fits. Also the lack of a steering damper and wide bars means that every little input to the bars translates to the bike. In my experience making it difficult to be smooth to drive out of corners while moving back on to the seat.
but Im really just nit picking since this bike aint really meant for that ****!
