hey everyone, im new to this shit so bare with me. alright, im 19 and im a pretty big speed demon. i had a 91 240sx done up to the shits and wud redline like krazy. im not intimidated by speed at all, i love the rush. im pretty good wen it comes to understanding speed, torque and all that other bullshit. my question is this...i wanna get into the sportbike thing, but i dunno wat to get. my parents r hookin me up pretty sweet thru richmond motorsports and im liking the cbr600 and the zx6. ive been hearing alot of negatives about the kawis, but i think they look better than the cbr. i kinda have a bad back, and im pretty short, 5'8. im not the biggest guy either, but im not a weakass bitch. wat bike wud be more comfortable for someone my size to ride hard and long on. money is no object so any suggestions wud help.
