Now I have never made this trip so I may be wacked out here. So set me straight if ya can before our trip next spring. BTW making the trip on a 1200 GSA and a 650gs. Ok a DS survives a fall better that a plastic coated sport tourer. But a 600-750 lb two wheel bike on gravel road, deep or shallow, is two wheels on a gravel road, regardless of the bike, within reason. Heck a low CG harley may be easier. lol. DS's provide, better crash protection, ground clearance, and suspension travel than your everyday, say RT (to keep it in the family), for example. I have not seen much in the ride reports regarding anything more than gravel roads, which most any bike with knobbies should/could handle. I assume there are some good DS roads up in AK, I just don't seem to see many/any in the RR's I am reading. If anyone can point me to some interesting threads or trips in this regard that would be great. Would love a little 'adventure' on the trip, if ya know what I mean.
