Motorbikes!

Hi again guys.
I currently have a CBR 250RR - Honda's high revving 250.  Made from the early 90's until 2000 in my country. It really is a great little bike to thrash around, with a redline of 18 500 rpm and around 45 bhp it is not slow, but really lacks the punch of bigger 600's. However learner bikes are all restricted until you have your full motorbike license. I only have about 10 months until i am allowed to (legally) ride whatever bike i want. Currently i am looking at 600 "super sports" meaning the full race style 600's. Now these things are fast, most topping out with a bit over 90 kw at the flywheel, they are more power than anyone will need on the street. Not to mention they look sooo GOOD!
Such as the:
CBR600RR

ZX6R

R6

GSXR600.

I know what you are probably thinking - That they all look the same. True, however once you start seeing these a lot, you start noticing the finer details which makes ( or breaks) the bike. I am leaning towards the CBR ( as i have it's baby brother) or the ZX-6R, as it has the best suspension and engine of all the bikes. They are all roughly the same price through private sellers, so as the date when im allowed to ride these big things come closer, ill be test riding to see which fits me as a person.

Let me know what you think of them! Or if you have any other suggestions regarding bikes don't be shy!
