Ya, sand sucks on these bikes. Not quite so bad if the sand is wet/damp. While riding the northwoods backroads in Wisconsin a couple years ago with a bud on a Harley, he turned off on a DNR fire trail. Said it was a short cut, to our destination. well, turns out, not! Wet leaves and clay are not a friend of the F6B either. Did manage to get thru without a fall. Have friends in northern Minnesotta, that have about 5 miles of gravel road to the location. Also not fun when it rains.
