I have been wanting to get a WR450 for some time now... I currently ride a DRZ400S model.. which I will keep for dualsporting.... But I been getting the itch to do some hair scrambles and the WR450 seems it will do just the job and make a good trail bike to add to my growing collection of bikes...... As money is no option... i am willing to spend the $7K on an 07 model... but at the same time, there is a guy in the classifieds that is not far from me selling an 04 WR450 with 800 miles on it... for $3500 bucks.... I know the frame and stuff are different on the new one.. but is the bike just so much better in 07? Or are the differences not very noticable?
