I am going to be moving up to a new ride soon, I am coming off a DRZ 400, I,m 6'2" tall weigh 175, and consider myself a pretty decent rider. I am majorly frustrated on what I want to buy though. I have narrowed it down to an 06 wr450 or a KTM 450exc. I have probably read 300 posts about these two bikes, I here people say the WR is reliable but it's top heavy and doesn't turn well. Then I read that the KTM is a " maintenance nightmare" , one thing about the KTM I like is how easy the valves are to adjust, no shim under bucket. Does any one know what changes have been made to the WR, I think most of the negatives I was reading were about 04 and earlier. Any comments positive or negative will be appreciated.
