I'm contemplating changing teams, from a DRZ400E to a WR450F. Although the Suzuki has been a great bike, I find myself riding less "trails" and more tighter, faster, technical stuff and figured the WR would be a better choice. Agreed? I"ve been reading these posts and it seems that the '04 might be the better bike? There seem to be problems with the '03 that was fixed with the '04 model. Is this true?
