one of my friends buddy has some old ass 600 something.. Ha i have no idea what it is except a 1992. well without me knowing or ever meeting the guy (till today) my firend set up a race for me. LOL guy seems kinda cool. but i am curious. what kind of 1/4 ranges do the older 600s have? i left my shit talking to a mininum due to my lack of bike knowlege. i know ill lose at least i think so. i have never really launched my car yet, but if anyone could kinda maybe help. i think he said yamaha? i dunno
