I started on a little 50 and now have a crf150f dirt bike. i've always been interestes in racing but some how have never tried it, which i know was probably a mistake. but now i'd like to seriously try it out. i have like 100 acres of land that me and my brother and sister ride on, but both of them never go out in the woods, whoops, etc. its most the open field and a few hills for them. honestly i think thats no fun haha, besides the jumps, but even then theyre not even that big. i feel im comfortable with it, and i ride fast in the woods. i can keep up with my cousin who's got a crf230f, but i realize that this late in the game there could be 12 year olds better than i am and really dont want to fail in the only thing i have ever really been good at. (i tried softball in school...definite NOT haha) but id really like some pointers on how to seriosuly get into racing and how to seriously get good. thanks.
Update: i live in mays landing new jersey
i've got a place called ATCO somewhat close to here.
