    I know a lot of guys like those, but it didn't work for me. I guess it was too wet here. Maybe I should have aired them down more. I ended up with a dirt knobby for the trails.

    For dual sporting I really like the Shinko 244 that I've been running on my XT225. I don't know how well it would last on a WR450, but it's been great on the little bike. Much easier to mount than the MT43 or the stiff knobbies are. They are very inexpensive too, so it would be cheap to test one.

    Take a look at seat concepts. For about 160$ they make a few different seats for our bikes that seem to be much more comfortable in the long run.

    Take your seat to an upholsterer. I got an inch of foam added in my seat, and they used the same seat cover. $40. Problem fixed

    My street plated WR450 has Guts seat foam. I can ride all day on it. I also run a trials tire -- you have to run them with low pressure 6-10 PSI -- and they are gold -- the wetter the better.

    Agreed, lower pressure is need on these so that the contact patch is correct. Higher pressures make for a crap ride.

    I'll have to try them again sometime. I'm sure that was the problem.

    Glenn,

    There's a great video on Youtube showing a trials tire going over a golf ball in slow motion and you can see the action of the tread gripping the ball. I have to admit that when pressured down they behave badly on the road, but they're a delight on the trail when aired down. Of course, they don't slide the corners like a knobby, so riding styles have to be adjusted a bit. if I recall correctly you were selling your WR...what were you moving on to, a KTM?

    I have a S.I.C.A.S.S. Racing tall medium density foam seat on my bike. It really helps on the long sections when you are sitting down. With the stock seat my legs were cramped sitting.

    No, the WR450 is perfect for me. I'm just selling it because I have too many bikes & ATVs, and could use the money for other projects. I'll be riding a little XT225 on the trails. I'll miss being able to blast up some of the tough climbs.

    I run a trials on my KTM 200XCW as well. They are just the balls for super technical terrain. Some people say they don't perform well in mud but I have not found that to be the case. Knobbies tend to dig trenches whereas trials tires float and grip. Only place I have not liked trials tires is in sand.

    hey, how tall are you? I've been considering a tall seat on my '07. I'm 6'2" barefoot, and 6'3"-ish with riding boots on. my legs cramp as well when seated. feel like I dwarf the bike. riser under the bar helps a little, but still cramped when seated.

    for some reason it doesn't seem as tall as my '01 426. wasn't sure if it's because I run a 19" rear tire on the 426 vs. 18" on the 450, or if there's a difference in suspension between the two (despite trying to even them up, the '07 still feels a little cushy-er).

    I am 5'11". I had the same seat on my '01 YZ426 too. Have you replaced the rear Spring? When I adjusted the rear sag on my "12 I am border line on needing a heavier spring which I did do on my YZ when I had it.

    The other bike in the back ground of my pic in the above post is ridden by a guy that is 6'3" to 6'4" and he has the tall firm seat and 25mm bar risers with I think woods tall bars. He put new springs in front and rear on his bike

    Have not replaced the spring, but I'm thinking one of the 2 P.O.s might have. Earlier this year after i bought the bike, I was trying to determine how to stiffen it up and whether I might need a new spring. I consulted the manual and it says there are color coded spots of paint on the spring that correspond to its relative stiffness. I found the paint on mine and it matches up to a factory code for a stiffer than stock spring. So I made some gradual adjustments to the damping and compression and that made a difference.

    It has a soft SDG gripper seat on it now which isn't bad as far as comfort. For some reason though that seems to be unrelated to either the suspension or the seat, the bike just feels smaller. Could it be the more streamlined design of the aluminum frame compared to the older boxy steel frame configuration? Both of mine are in the garage side by side and the 450's seat height is lower where everything else for the most part is the same. Sitting on both, they feel roughly equal as far as sag is concerned.

    Not a big deal I guess. I just don't care for the bulk of my weight while riding seated to be on my undercarriage. Seems like more weight needs to transfer thru my feet to the pegs making it easier to stand quicker. I've got lingering back problems as it is and long miles take their toll regardless. Not that I have any plans to quit of course :super. So maybe a tall seat is the way to go.

    Starting in 05 they made the bike about an inch lower from the seat to the ground. I had a 2000 wr400 with stock seat and lowered pegs. on my 06 wr450 with lowed pegs I still felt cramped so I went with a taller Guts seat. I'm 6,2 almost 6,3 barefoot.

    I guess I'll have to do the seat mod too, on my '12. I'm 6'4'' and I find precise braking (rear brake) very difficult due to the angle of my ankles.
