Ok, so I've been riding street for 7 or 8 years and riding track for 4 of them, mostly on a 2007 Yamaha R6. I'm thinking I'd like to add a dirtbike to the stable, but I have zero dirt experiance and I'm having a lot of trouble narrowing down my selection. I'd love to here some recommendations. My price range is $2000 to $6000, but I'm leaning towards the low end if I can get a good and reliable bike without too many sacrifices. The high end is essentially there, because I'm really liking the idea of a 2012 KTM 350 SXF. I'm not sure what type of riding I'll be doing. I will try it up at IMI, on trails, or wherever. It does not have to be road legal, but wouldn't hurt. Otherwise I'm open to ideas, 2 stroke, 4 stroke, 250, 450, carbed, fuel injected, motox, enduro, etc.

Thanks,
Matt
