Hi, i have a kx250f right now, and i want to upgrade, i have been looking into the wr450f. Can you give me some info on the bike. How is it for power, comparable to say a cr450f, i imagine it would be geared different and what not, and someone told me the bikes where top heavy and felt very big, is this true. Has anyone jumped with it and if so how does it perform....basically can everyone just let me know what they think of the bike i would really appreciate that..THANKS!!!!
