The gixxer makes for a better street bike thats for sure! I am a die hard GSXR person,but like i told you i will deff own a r6 one day. You cant ride an r6 gently! You have to beat the crap out of it to get to its power band. The R6 is deff meant for track riding and thats what it was mainly designed to do. The GSXR is also for the track,but it is allot eiser to ride on the street due to the way the power is made. I have a feeling if i got on the r6 at the track i would deff beat my times that i can get on the GSXR600. Let me show your friend what an r6 can do lol.
