The BMW and the KTM are both great bikes with the best possible riding positions. I own a GSA, but I spent some time on the KTM 990 Adventure before I made the purchase. The GS has better wind protection, shaft drive, and tubeless tires that can be plugged on the side of the trail in 10 minutes. Those were really the deciding factors for me. Other than that, the KTM makes better noise, feels lighter and more nimble, and I LOVE orange. You really can't go wrong with either. I still own my Harley, but it doesn't get out of the garage much now that I have the GS.
