not!! lol just to show it cant be done.
heres the front clearnace
and heres where it hits in the back not the front beleave it or not
here is the rear clearance w/ my 26" pxt's on it as you can tell not enough clearance for 26"s tires either. moral is boys on the 08'sportsman 400 i guess 25" tires is going to be the biggest.

 

They hit in the rear not the front, go figure! LOL!

 

I don't care who you are, that's funny! Never would have figured clearance issues with the rears, either!

 

I have Mudlite xtr 27's on my 07 700 and the fit fine. I had to move my front tierod to the bottom of the bracket, but other than that they fit fine.
Is that the new little sportman?

 

Holy Crap Stendori, that is one tough looking HO. Very Nice.

 

LOL!!

You won't have any problems if you turn it into a hardtail.......LOL!
