I did this route on an Electra Glide the week before this year's Black Hills Ralley. Spectacular scenery and good road surface but the rider doesn't get a whole lot of time to enjoy it as absolute concentration is required. The Iron Mountain Road section is very challenging, particularly the 1st gear switchbacks. This ride might be a bit too much for a new rider. Sure would be fun on a Ducati 996 though.
