i am not as young as you but when i started racing my raptor this summer the problem i had as will you is you will have to race 450's and 400's all day! there is no way that bike will keep up with those bikes unless you are a way better rider! i dont think tt would be good for that bike because of the speed it has. i did fairly well on the track because i was faster in the corners than every one else but strightaways no way! although sand mtn has a race this sunday and they are the only ones who have a 350 and under class! i might even race my rappy in along with my yfz!
that is the only advice i can offer!
