It all depends on how much you love your FJR. It will come back battle scarred. So if your a spit n' polish Feejer guy, who agonizes over scratches, marks, dents, torn plastic, pock marks on the undercarriage and on leading edges, then no, don't take the FJR. Pretty much plan on dumping the bike somewhere along the trail.
As practice, to see how you really feel, go to your garage right now, take the bike off the centerstand, then toss it down to the ground, your choice as to which side. How do you feel now? Ambivalent? Hey that was fun? Then take the FJR to AK. On other hand, if you feel like 'Oh crap, that just cost me 600 bucks' and look at that broken mirror, bent slider, torn plastic, then you really should take a 'throw-away' bike to AK.
Me, I'm riding a totally farkled used DL650 that I have less than 6k into. Even if I have to leave the bike in AK it won't be all *that* bad. And bent bars, scratched plastic, warrior wounds to me, on that bike, are badges of honor well earned.
YMMV,
4 Dollars Please :lol:
