Howdy folks, I'm in the market for a dirt bike and am looking for opinions. I'm 40, about 6'3" 210 lbs. I've ridden street bikes for the last 20 years, mostly ZX6R's. I'm off the street now (lived this long, don't want to push it the way I ride) and have about 10 acres to ride on in my back yard. There is already remnants of a old track there with berms and jumps, highest jump is about 5 feet. I've been bush-hogging it and am quite stoked. I want to buy new. Looking at the KDX200, TTR250 and the CRF230F. My budget is about 4K. What do you think?
