I also have to offer up the Suzuki DL1000 V-Strom. I'm on my second (the first was murdered by a Honda mini-van) and it is reliable, low-maintenance, 87 octane drinking, no oil leaking, easy chain drive, (relatively) low seat height, comfortable cruising two up all day at speeds from 45-95 mph. In three years and 19,500 miles of riding I've had one factory service because I'm too chicken to mess with valves. Otherwise I've done all the service and farkling. The bike is rock solid reliable, easy to work on, and great to ride on anything from superslab to poorly maintained fire roads.
I've not ridden two up on anything unpaved, but if you and your wife are willing to go there, cheers!
And yes, they're available for 2013. AND there's strong reason to believe an updated model will be available for 2014.
