Although it has been a few years ago, I was sponsored by a Honda dealership when I raced motocross. That was a pretty cool deal for me. Anyway, I don't have info on the specific bike you are considering but I know Honda fairly well. /forums/images/graemlins/wink.gif Since you are buying a new bike, I don't see how you can go wrong with the CR series Honda bikes. They are about as durable and reliable as you can get.
I've owned more bikes than I can count and even ran several that I didn't own. In order, my favorite four dirt bikes would be Honda, Yamaha, Suzuki, and Kawasaki. Nothing against others, but I've personally raced each of the above mentioned bikes and had great success. I have had a few other brands that I didn't care for at all, but I won't mention them. I figure it would be best to just mention the ones that I really liked. Anyway, good luck! I'm sure the CR250X would make a great bike for you.
