Snow, you say? Did Idaho peak the day before. Here I'm coming back down from Reco/Payne where the saddle to cross is at 7500'. None of the quads made it either, about even-steven. We were about a week late to try it, I figure.
Drove the 800 Trail for well over 1000 Km. (620 miles) in 2 weeks, from Utah dust and elevations to 11,450' to Sandon's snow the CF Moto never missed a beat, broke nothing and needed nothing. All I put into it was gasoline.
