It may be outside your original route but you might want to search Google 'images' for Shafer Trail in Utah. It's about 30kms West of Moab, Utah. I rode it a few years ago on an 800gs and my knuckles were white, all the way. I don't like heights which of course, was the whole point of riding it. Utah is spectacular. If Shafer Trail interests you, message me and I'll send you or post GPS coordinates. I also did a 20 minute video of it. All the best on your trip.
