I have a 2008 600RR. I like it a lot, especially with the electronic steering dampner. It's my 3rd 600, but with my knees not being the best and being about 6'2'' I think its time for a change of pace to a cruiser, even though I have been eyeing both a repsol 1000 and a honda 919, which is still new, however I am not for getting hit with all the wind unlike the sport bikes.
you will not regret that buy, i have two friends that ride them(one is on this site) and they are really fast guys in the curves.and they have never said anything bad about the bike that i can remember.
I have a 1981 suzuki 550 gsl, This thing is in perfect cond. Haven't had it out for about 5 years, thinking about this year though. My parents gave it to me on my 17'th b-day. Don't ride anymore,but can't part with it. Will get it out and take some pics. this summer.
