2009 Yz 250 Wife Ratio Transmission

Does anyone know if there is such an animal for this particular model?

manufacturers do not sell different ratio transmissions, only different size front and rear sprockets which allows you to gear a bike down (better for trails) or up (better for high speed)

A WR450 Transmission will fit in your 08 YZ250 cases...

Jag,
That is not always a true statement. There have been several times a company has made a moto version and then took the same platform and made it into a woods bike. Adding an 18inch rear, softer suspension, and then removed the narrower 4th and 5th gears and changed them to taller gears. I think that is what Bwalker is talking about.

well, having to decipher what he really meant by "wife transmission" complicated matters
:NOD:

Sorry gents. I have not completely mastered typing with my thumbs on a smart phone yet.
Yes I was referring to a "wide ratio" transmission gear set.
Looks like the wr450 gear set will work so I will research that.
