Well today was the day I got to take the new WR 450 out. Its pretty awesome and for those who think they feel heavy I would say this is not true for the 2005. I have a CRF250X and not comparing motors but the overall package I like the yamaha better. It handles well stock. I hit everything hard and it handled it without one harsh bottoming out. I am an X motocrosser and would easily go out race this on the motocross track. As a matter of fact I will soon.
