I want to buy a bike, i have had 2 different dirtbikes, so i know pretty much the basics to riding. I am 6 foot and about 170 pounds. I have about $2000-$3000 dollars, and i can't decide whether or not to buy a 250 or 500. I rode my friends 500 and i think i can handle one, but i dont think i can find a good bike for $2000-$3000 dollars. So basically can i find a good 500 for 2-3 thousand or should i just get a 250.
