OMG I just rode my brother's Ninja ZX10-R.
your powers of observation are astute.
snotcycle: go easy, respect the bike and you should be ok. The biggest jump wont likely be the power (altho ya there's alot of power) it'll be how hard the 600 wants to drop in. Particularly if you're on fresh tires, as they wont have "chicken strips" worn into them. Modern 600s are more capable of dropping in far enough to drag parts on the ground (rearsets, bar-end mirrors, side exhausts). it'll be the hardest thing to get used to. 600's are atleast somewhat easier for new guys 'cause you can be abit more wreckless with the throttle and so long as you're not in the right (wrong?) gear, it wont get to out of hand on you.
also, take a lesson from the dude in Joe's pic, and make sure you've got good footing on your pegs at all time, if you jump around on the bike without being firmly attached to it, it'll pitch you (unless you're a racing god, in which case you're not taking my advice, I'm taking yours).
everybody please ride safe.
