YZ450f vs WR450f...educated opinions needed...
Posted May 19, 2003 - 01:36 PM
a)Has anyone ridden both bikes on a desert racing environment (we live in the baja)?
b)The bikes have different gearing, I can't seem to find the gearing ratios for the WR wanywhere on line, do you know if the finel gear ratios are the same?
c)How difficult is it to get a stator on a YZ (need lights for night races on the baja)?
d)Has anyone tried putting 19" tire on the front of this bike to ride better in sand?
e)Other than some of the tunning and the obvious happy button (e-start) is there a large reason why not to do this?
Thanks for your help and tolerance..

The WR 450 ratios are the same as the 426, but the primary ratio is one tooth taller (21/62 to 22/62 on the 450s).
I forget the final ratios but they are w/in a tooth or two of each other. The lack of fifth on the YZ, and the super tall fifth on the WR, is a gap you can't bridge with a sprocket change. Fourth gear in the YZ is the same ratio as fourth in the WR, so all else being equal the WR has 20% more top end right there.
Hope this helps.

Doesn't Ty Davis run a YZ450 in the desert with pretty fair success? I have often wondered about this.
He gears it to the moon, like 15/43, and hopes he doesn't fry his clutch and rear brake in the tighter sections.
After he and Pearson did so well at Lucerne I called Zip Ty Racing and asked about the gearing and tranny they used. To my surprise Ty himself got on the phone. As I recall he said they got the YZ to go about 90 w/ that gearing and the stock four speed. I asked him about first gear and he said it was indeed very tall but not a problem.
But then, he is Ty Davis.
I am not so I went with the red five speed.
