You will soon be able to buy a Kawasaki Versys 1000 in the U.S. Consider it, I've had mine for a year and it's virtually replaced my FZ1 and KLR650. The *real* adventure types are going to winge about the 17" cast wheels and the 4 cylinder engine. But for normal use, including lots of gravel roads like the Dempster Highway, it's fine, and much better on the highway than a lot of more "adventury" bikes. Will do two up well, you won't be short on power or comfort. Might still be a little tall, but there is a price for 6" of suspension travel that's hard to get away from. Comes with ABS, traction control and power modes as standard. Think of it as a Ducati Multistrada for a faction of the price.
I won't get rid of my KLX400 for actual dirt bike use, but the Versys 1000 can otherwise be a one bike solution. You'll note that even KTM, the most "adventure" of the big bikes has toned it down for 2013 towards what most people actually do.
You can check an article on the Versys online at Motorcycle Mojo magazine.
