...this guy did it on a Piaggio Scooter, MP3 (500cc). Not a Harley, as a matter of fact he takes a few swipes at Harley riders but it is a good read with lots of photos. Something to keep you snow bound northerners busy. Modern Vespa : MP3 500 to Alaska I posted it here since this was not an actual trip taken by me. Mods feel free to move it wherever you feel is appropriate.
