I am looking for a dirt bike but don't know exactly what I should get. I am 17 years old and I am 5'9" and 140 pounds. I know how to ride and I am looking for a used bike that costs around $2500. I am looking at a 2004-2006 model of either a Honda CRF250R or a KX250F. Are either of those good bikes for me or should i look for something else?
