Been a LONG time since I posted on here. I had my 600RR in April of 03, and by September I traded it and the SPEED Channel 636 for my 954. After some thought and thinking of the big picture I may come back to 600's. Now I have ridden the 600RR, 636, and an 04 Gixxer6. I'm a little up in the air as to which to get. Two downers to the 600RR to me are plastic tank shell(so no tank bag), and the center-up exhaust leading to the dreaded lack of cargo space for anything much larger then a damn band-aid. Any thoughts? I know most will obviously say the 600RR.
