i had a similar choice, zzr600 or rc, and i chose the rc hands down, love the bike in every way, she might be as bit porky, but thats ok, she moves just fine. and im not a racer and dont stress lap times. i enjoy riding and the rc is a more enjoyable machine for me. i also commute on zzr1200 and that thing is a beast of its own..
