Sport bike suggestion?

Next year once I start college I'm going to buy new bike(first sport bike) and I am thinking which one of these three: Kawasaki Ninja ZX6R ; Honda CBR600RR ; Suzuki GSX-R600.

Compared them and they all are similar.
I haven't sat on any of them yet because it's kinda hard to find any here where I live but I will eventually.
I'm 6 feet tall and weight 180 lbs.
I have enough experience with bikes so please don't suggest 250cc.

So if someone could say pros and cons of each, any big differences, comfort etc etc anything will help

Experience with street bikes, never tried dirt bike

You left one out! The Yamaha R6.

When you say you have experience with bikes...do you mean STREET bikes or DIRT bikes because they are two different beasts. To honor your request i won't preach, but i DO NOT reccommend someone new to street motorcycles starting out on a supersport 600.

Now of the bikes you mentioned. Honda has made quite a name for themselves in MotoGP for having very high performance (and winning) bikes. Though, i don't particularly like the CBR (just my preferance) even though it is by no means a bad choice. Suzuki, to me are too generic, but still good bikes. The others... about the same as the suzuki and the honda.

The four big name japanese supersport 600s are all pretty much identical except for ergonomics and styling. Performance numbers are all so close that you'd never notice the differences unless YOU are a MotoGP racer. If i were going to buy a jap 600cc bike i'd probably get the R6. If i were getting any 600 i'd probably get a Triumph Daytona. Of the three you mentioned, i'd get the Kawasaki. There's a lot of people around where i live that drive the zx-6 and the ZZR (nearly the same bike) that seem to like them a lot. The ones i've talked to love theirs.

The bikes you mentioned are ALL good bikes, so it should boil down to what is most comortable for you to ride and whether you like Kawasaki green, Honda red or Suzuki blue!

The CBR is alot more nimble and agile, and also the most comfortable for me. Being just 5cm shorter then you and 174 lbs I think that you would probably have the same feeling on a cbr as i do. The Kwaka Ninja although a sports bike feels alot more upright to me so if your used to have your wrist under some downward pressure (which is stereotypical of a sports bike) you might not feel at home on a Kwaka Ninja. As for the Gixxer I dont have any experience with them, my advice is to test ride as many bikes as possible and get the one which best suits you and your needs. Also join a motorbike forum, their great help concerning all topics of riding.

Instead of choosing the crotch rocket-race bikes that you're not going to afford to pay the insurance premiums on buy a standard-naked sports bike like the Yamaha FZ6, Honda 599, Kawasaki 650 Ninja, or Versys, or the Suzuki SV650.
The Yamaha FZ6 has the same engine as the R6, except its tuned down for lower rpm's at normal highway speeds, its only about 10 to 20 mph slower than the R6, but you're not going to be spending most or your time riding at 140mph.
Insurance is much lower for these bikes and they offer a much more comfortable riding position and less work with the throttle.
