Those are all slow 4 stroke 250's (waste of money you will get tired of it). Get a yzf450(fourstroke) thats basically the equivelant of a 250cc 2 stroke(badass bikes). There is hardrock in ocala, theres a track in lakeland, track in mulberry,track in dade city,track off 118th street(clearwater I believe). There is also CROOM in brooksville basically a shitload of land for dirtbikes and what not, good place to learn and just have fun, they have huge hill climbs,jumps,trails, camping etc.
