For street consumer use I agree that statistically ABS saves lives, but does traction control? Not so sure.
Does a computer controlled suspension, does it save lives? Would really like to research and find the statistics.
If I was planning a trip to Alaska, I'd go one of two routes:
1. I'd find a well taken care of F800 BMW(I think that's their entry level dual sport)
Or
2. I'd find a nice KLR, DR or XR single dualsport!
I'd stick to as many fire roads as possible and have an epic trip!
Unless you have support vehicles in tow I think a massive 1200 adventure bike is total over kill. If you need help biking up your bike, it's too much bike! And last thing you want is issues finding parts if and when you do break something.
A friend of mine road from California to Argentina on an 86 BMW R90(think I got that model right). He only had one issue with his bike the entire trip(starter) and it was one he knew he'd have to deal with, so he was prepared for it. Biggest mod he made to his bike was upgrading the suspension front and rear to handle his gear and the terrain.
Also, I'd pack as light as possible!
