Hmmm, I hate to bring this conversation back on topic, but I am struggling with this very decision as we speak. I sold my 600rr a while back and have been itching to get another bike for a while now, but I am having trouble justifying getting the same bike. I am very interested in the 1000rr, not because I believe I can outride a 600 but because I have never owned anything but a 600 and am curious to try something new. I even considered a Gixxer 750 but decided that I just can't pull the trigger on anything non-Honda. I've found a place selling new 06 1000rr's for $8800 OTD and am almost certainly gonna pick one up in the next week or so. I figure I will give it a shot and if I like it (and it doesn't kill me) all the better. If not, I'll sell it and get another 600rr. Either way, its gonna be fun (except that possible "dying" part). I just wish Honda would add some of the cool stuff the other manufacturers are putting on their bikes (like the gear position indicator, projector beam headlights, and integrated turn-signals).
