This paved section of Top of the World Hwy is accessible only by 20 miles or so of dirt/gravel road. For that reason, i'd say it's a great route for ADV bikes. But once you get there, it is outstanding - amazing views on incredible smooth blacktop. This was one of the highlights of my ADV trip to Alaska.
Gas stops are minimal, consider carrying fuel. Moose and other animals are ever present be aware.
Lots of Moose to see (and avoid!) so beware. Beautiful Alaskan scenery.
