I own an '05 'X', and I've been riding several trails in Michigan that are extremely sandy. When I say sand, I mean its really like deep fine powder. I'm over 6' and 235 pounds, and find it very difficult to keep upright sometimes, and always feel uneasy when the bike starts steering where IT wants, not me. I'm gonna tag a tree sooner or later unless I can get more control. I've already changed the fork and shock springs for my weight. Any suggestions on good tires for this type of terrain? Maybe changing the suspension settings? Any info is appreciated. Thanks.
