My buddy just bought an 06 R6 with a 2 bros. slip-on exhaust and everything else is stock. He claims he could "kick my ass" in at the local drag strip. I have an 03 RR with both the drive sprocket and rear sprocket geared for acceleration (+1/-2) and a custom mapped PC. I realize rider skill has a lot to do with it, but we have both been riding for a few years now. What do u guys think my chances are?
