Dude I just went through the same process in slightly different order. I've been lusting after a KTM 990 for several years but have always been a BMW guy with a 2010 F800GS (prior to that had a 1999 1100GS). When I heard that we might be looking at the end of the 990 model I jumped on a 2012 Adventure. Since I've sold my both my BMW and my Vstrom.
I'm curious as to why you went with KTM instead of another 800GS? Cheers! And we like to see pix.
