we rode this in july, a bit scary no guardrails, loose gravel road, only hairpin turns are paved and road crew was blocking portions of the road! poor visibility on some turns, and has two way traffic.
Outstanding. The Moki Dugway is an 1100 rise over 2 miles up the side of a cliff. Very tight switchbacks on a gravel road. Best for Adventure bikes although we went up and down it quite safely on rented Harleys. Lot of fun!
