man you guys are flaming him hard for suggesting a 750. while i understand where you all are coming from, it Really depends on the rider. some people are naturally skilled, some pick up riding very easily. also keep in mind how many kids rode dirt bikes for years or have been around motorcycles for a long time before riding themselves.
me personally, i had virtually no option of going with a 600 or 750 and most of the literbikes are pretty much the same size. i guess i'm pretty much too big for a crotch rocket but i ended up on a TL1000R and did just fine, about my only other choices were the busa, cbr 1100xx, zzr1200, zx12r, etc. never been on anything before, i took the msf rider course and i was one of the best in the class. the main thing is i knew better than to hop on and rip it, i started slow and just rode around town, getting used to the riding position and starting to lean a bit. i slowly bumped up the pace and started using more throttle as i felt confident that i could. by the time i had the bike for a couple weeks and i had gone faster and leaned more just a little bit more each time, i was pretty much able to keep up with any of my friends when they're ripping straight or knee draggin a curve. if you're mature enough to stay away from the throttle when you start out, you're fine, just pick a bike you're comfortable on. sometimes you have to swallow you're pride, the first time i swung my leg over something, i was in a large parking lot, going in a straight line... yea, i felt like a retard, but if i was on the street when i did that, i think it woulda been very likely i woulda either gone down or gotten hit.
do what you want man, the newer 600's arent slow, you just need to be in the power range which even i noticed when i switched bikes with a couple buddies... for example, an 03 R6 will pick up in first gear with me on it, it just takes til about 10.5-11k rpms and i'm a 350lb guy, so it does take power to do that.
