Rear Tire size

I have a 09 WR450F and am replacing the tire. The stock width in 110, has anyone tried the 120 width? Is there clearance issues or performance pro's and con's?

I have a 140 on my '05 with no issues, I like the extra width.

X2...except I don't have a 140 on currently.

I run 120's on both my '07 450 & '02 426. No clearance issues at all, go for it!!

I'll run 110 if it's a muddy course or lots of ruts. Otherwise a 120.
