YZ/WR trans ratios

[TexXR]

Can anyone tell me how, if any, the ratios for the first three gears differ on the YZ426 and the WR426? Also, does the WR use more flywheel weight?

I was told by my dealership that the WR does have a heavier flywheel, and that 1st and 2nd gear were shorter, while 5th was taller on the WR than the YZ. This is of course info from a salesman so I'm not guaranteeing its validity.
