Swamper- I thought the WR250 was much too soggey in the deep whoops stuff, but yet it was also stiff + choppey on small sharp stuff. It could be improved on both accounts, IMO. I could shove it right through the travel and make it wallow, whereas my KDX would've soaked it up and asked to go faster. (I'm going of memory, the KDX has been gone since last fall) The other grumble was that the WR doesn't have a power burst to lift the front wheel when needed. If needed, I could easily pull 4th gear wheelies with either the 200 or the 220. (the RM250 needs to be carefully monitored to NOT pull 4th & 5th gear wheelies)
For the handling part, I thought the WR was a bit top heavy (plus TALL) and it seemed to want to get away from me in those awkward moments.
One thing also about the KDX, is that the cornering will get much better once the fork has a valve kit. The valve kit helps stop that awkward feeling of the front end kniving under. Note that even with the valve kit, a KDX will still feel awkward if you REALLY stuff it into a corner, and that's why I moved on to something else.
I dunno, maybe I was trying to ride the WR like a two stroke motocrosser. When I get into trouble, I like to grab the clutch and bust into the powerband, and the WR didn't have that rip-snort burst.
Bottom line, though, is that if you like the WR better, hang on to it. We all have different riding styles & abilities, plus riding different terrains, so naturally our preferences will be different.
