So what Wr 18" rear wheels are compatible with a 426?

So all my understanding was the Wr426 rear wheel had a 18" rear wheel. Well, my mistake was to order a 18" rear tire to find out it had a 19" Yz style rear wheel.

So I would love to have a wider smaller tire on the rear, but don't know which rear wheels are compatible.


{Plus, I found out the rear sprocket is 50 tooth, also which I am sure is also wrong with OEM standards for the WR426

That is awesome, thanks!


Now to find a affordable 18" rear wheel.


What is the stock gear ratio for the sprockets?
