im a dumbass? what was your first bike? and how long was it b4 u wanted 2 upgrade? every1 i kno that buys a 600 ends up selling them for a 750 or bigger within 6-8months!!! thats all im saying, save urself the time and money u might lose selling the 600, and im not saying for every1 to run out and buy a busa, 1000 or zx14!!! a 750 is easy enuff 2 learn on but also enuff to scare the shit out of u wen u get sum more skillz! regaurdless of what kind of bike you start with if you ride SCARED and respect the bike you should be ok
