What he said...in all areas. I just picked up a WR250R from a guy that had it set up for sand (lives in FL) and had done some of the Western TAT. He had 17" (I think) and fat tires ala TW200 and he was breezing along in the sand and talcum powder out West while the guys with 21" wheels were struggling. Having some experience riding sand, I can tell you that skinny tires and high CG don't mix. The guy on the Harley was breezin due to fat tires and low CG...very stable combo. You've got to maintain enough speed to keep the front (and rear) from plowing into the sand...it's like a boat coming up on plane vs pushing a huge bow wave. Not to offend anyone here, but when I see these "adventure" bikes with a big top case perched up high on the rear end, I have to laugh. I use a Giant Loop Great Basin and load all the heaviest stuff down in the bottom on each side...huge difference in how the bike handles. The only things that go up high are lightweight. It's raining in N.Ga today...bummer! Think I'll go take the new WRR apart and get to know it...PO did a lot of electrical mods and that makes me a little nervous...most folks don't understand electrons! Cheers!
