Good one. I hope your either joking or simply confused. If the crank was changed to shorten the stroke or they went with a shorter connecting rod, the effects will be at both the top and bottom end of the stroke.
One other note (not to you Riznaptor), the motor is based off the WR450, not the YZ from what I've read. I am guessing they did this for the extra torque to help lug the extra weight around vs the YZ.

I know that the crank is the only thing that changes the stroke. The yz has more compression b/c of the longer stroke is what I am saying. I figure the used that same length rod and used a piston with a long compression height, but without seeing the specs who knows.
