i also suggest the cassair with a side trip into stewart/hyder. then across the campbell from watson lake to carmacks, stop at mayo/kino, drive past the dempster turnoff into dawson for a break/resupply/systems check, then up the dempster and back, dawson, over the top to eagle, then chicken, and connect up to your route again. your gear needs to be in top shape and make no assumptions about fuel availability. those gravel roads change constantly, be cautious, you can be a long way from help. if you are unfortunate enough to run through a calcium chloride application, you need to power wash at the first opportunity-that stuff sets up like concrete. as for the dempster, it is notoriously greasy in the rain, still has sections of crushed shale on the road surface, high winds around the circle and divide can make those sections dicey, and the ferry landings can be only minimally graded with bank run material-sometimes challenging on a loaded bike. that said, the dempster is still one of the great rides in north america, in particular up to ft. mcphearson.
