Barty this is only my opinion take it or leave it.
I have a mate thats recently bought an 07 Wr450 and put the yz white plastics kit on it. It looks really good and he gets to keep the original kit stored for when he resells it.
I have only ridden it once at Woodhill but it did seem a bit tame. Like pickin up the front over roots etc compared to the CR hit. I have also noticed at places like Ardmore, Harrisville and Kimis watchin the Wr450's they seem quite soft for MX track type stuff and open fast trails.
We went to Thunder x and it was really really muddy, weekend before last. Like the Vids of the Pussy Pounder. The Wr took those conditions much better than the CR. The WR was handling it quite well where my Cr was like a thoroughbred, more tempremental, to High off the ground, skitish, wheel spun extra quick. And I have got revalved suspension and a fly wheel weight.
Finally, I rode with a mate at a Trailbalzer who is a really good rider and him and his mates even though its a trail ride basically end up racing around the tracks flat out. If you are a good rider that likes to push it, I don't think the Wr would flick your switch. Get the yz and revalve the suspension for your riding stlye.
So if you like the more technical cross country stuff Wr or Exec but if you like a good hit and the fastest pace you can manage the YZ450. The Honda 450 is a damn good bike as well.

On a Motorcycle you're penetrating distance, right along with the machine!! In a car you're just a spectator, the windshields like a TV!!
