Just did like 20+ miles of a sand road that would've been a breeze on my CRF, but it was hell on my XR. This was Jawbone at the south entrance to the Sierra Nevada mountains.
Eventually I let my guard down and took a pretty good 30+mph digger. Besides cleaning my clock, It cost me my windshield, right mirror and things are just a bit tweaked. No way would I attempt Glamis. Whole new respect for the Paris Dakar folks.
