I am currentlly running 589's. Which are working out pretty good. I have ran 25" mudlites in the past that did really well as an all around tires (they are alot lighter too)
yes, the 25" mudlite xl's would be a great choice. that's what i run and i am more than pleased with the performance, not just the performance, but the added ground clearance. i would recommend an aftermarket exhaust and filter first though. it does make the bike a bit sluggish if not. just my 2 cents.
