I am amused by this... I have owned both a R1200GS and a KTM 990 Adventure. The KTM is absolutely and unquestionably totally superior for a big bore twin dirt bike as soon as you leave the pavement. It's not even close. However, the GS is by far the better road bike. Long distance rides on the KTM 990 Adventure on blacktop were not fun. Stick either one into a mud bog or launch one into a ravine 6 feet down from the trail and you will realize that both really suck as dirt bikes. They are both FAR too heavy to extract without a small army or winch to help. Been there, done that on both as well. For the record the new GS (which I LOVE!) has the fuel tank down low, its the airbox that is on top now.
