I've been riding for no more than 2 months. So far I've just been borrowing my cousins old YZF600R. But for the past week he's been letting me give is 03 R6 a try and to be honest...I feel very comfortable (maybe even more than the 600) on it. The original deal was for me to "evaluate" the YZF600R to see if I'd like to buy it off him as a learner bike and get the kinks out before I step up to a new..or somewhat new R6. Now, I'm having question whether I want to spend the money on his 600r and instead go for say a very slightly used 2002-03. Suggestions?
