After upgrading from a DRZ400S to the WR450 I was really happy to have a bike that was so much better on the trails. After the dirt knobbies wore out, I tried a DOT knobby on front & a DOT trials on the rear. That was a HUGE mistake, especially the DOT knobby front tire. The WR felt like the DRZ did, terrible handling off-road. I think the DRZ probably would have been a much better handling bike on the trails if I'd tried a dirt knobby front tire.
