well if a bigger fits it fits.

and makes a bigger difference.

15 is common and may fit.

a 15 would not fit my 09 crf450

my aprilia sxv has a 18t front sprocket lol

you can change the rear to the smallest avaliable but you may find it will try to eat chain sliders.

No. Stock WR comes with a 13/50. If you want to make it better for highway go to a 14 or reduce the rear to a 48 or do both.

Oops that is for a wr450. I'm not sure about a 426.

I run a 16 on my super moto it's a 426

putting a 16 in the front  does that eat up your chain slider? and do you even need a chain slider? also I heard taking one tooth from front is like taking 3 from back. ?

It hits it ,but the chain doesn't rub on that part of the guide. And yes 1 tooth on the countershaft is equal to 3 on the rear..
