The competition for this segment of bike is really the Concours 14 (obviously), the BMW K1600GT, the Yamaha FJR1300 and, to a lesser extent, the Honda ST1300. You can kind of also shoe-horn the Honda VFR1200 in there with its bags, and, if you like, the Ducati Multistrada Granturismo, if you're like me, and like options. BMW also has a new R1200RT coming out this year with the "precision cooled" parallel twin from the GS, which should put the power-to-weight ration on-par with the K1600.
The BMW is the best all-around bike. It's also the most expensive, by far. The FJR was updated last year and is a very decent bike -- the closest competitor to the Concours for value. The Honda is more expensive, hasn't been updated in a decade, and is basically waiting to be replaced. The VFR is pricey with the options and the riding position is very sports-oriented. It's the highest-performing bike, if included, however. The Multistrada is a supreme bike, I think it's the second-fastest behind the VFR, it's comparatively light, and can go offroad, but lacks cruise control and wind protection.
I've been following the developments of bikes in this segment (and close to it) for the past two-plus years very closely. I'm hoping that Kawasaki adds cruise control to the Concours very, very soon. Some days I wonder if I should just save a little more money and get the BMW. Other days I think it's crazy to spend that kind of money on a bike when one can get a left-over Concours for a very decent price (I like to buy new). The FJR is very competitive, but I hate the color. My sense of nostalgia wants to wait to see what Honda does with the ST1300 (I've been riding Honda since I was a kid and currently own two). On some days, I think I want a Ducati Multistrada 1200S Granturismo so I can do some adventure stuff combined with the S/T part. Argh.
Whatever I get, I want it to be my commuter bike, run around town bike, and touring bike. Basically, my do-everything bike. So it needs decent wind protection, heated parts (e.g. grips, seat), cruise control (or the ability to easily add it), very decent acceleration, and good luggage capacity.
Decisions, decisions.
