Good to see a fellow small bike rider. Here was my trip to AK in summer 2010: http://advrider.com/forums/showthrea...light=dabinche
I'm planning on going south of the border this winter. I won't leave the BayArea unitl the weekend of Dec. 17th. If you are gonna be going around the same time we should meet up. My current bike is a 83cc Tomos Honda: http://advrider.com/forums/showthread.php?t=741115
This bike is still being worked on but should have everything done by the leave date.
Funny thing that you mentioned about having doubt doing the haul road on such a little bike. I, momentarily, also had the same doubts you had.
