The seat hieght is actually reported to be just under an inch lower than the 07-11. I would assume it was the 12s stiffer suspension holding the bike up higher in the stroke.
I sat on a '12 WR again today at the dealer. I have a 30" inseam and can barely touch the ground. I am on my tippy toes. You cannot trust the Yamaha
specs. The YZ450 seat height is listed at 39.4" and the WR450 at 37.8". Not true. I sat on the 2013 YZ450 and it is noticeably shorter than the new WR. i could almost get the balls of my feet to the ground on the YZ. It also has a lighter clutch pull than the WR.
For comparison, I sat on a new CRF450X and CRF250X. Both Honda
's were lower than the YZ and with much lighter clutch pull. The clutch pull on the 250X was so light, you could operate the clutch with one finger all day long.
They wanted $7500 for the 2012 WR450F, $8000 for the 2013 YZ450F and $6000 for the CRF450X. The 450X is starting to look good.
