I'm club racing in an organization which has produced some of the best riders in the world...including a couple of MotoGP winners. I'm watching two or three future superstars right now and the ages are between 10-15. These kids are unreal on the track and they are they getting professional assistance and limited sponsorship. Last year I went up against a 16 year old who has run in the AMA and done very well. We were on the same make/model and equally prepared machine. That kid made it look like I was going backwards. OP...unless you're under 16 and already winning races in one of the large club series you can forget it....save yourself some pain and money..buy a Ninja 250/300 which is race ready and go have fun at your local track.
