My GS is a great bike, incredibly comfortable. However, the 1200R got my blood pumping. I found the riding position vastly different, almost sportsbike like, but enjoyable. Felt slightly cramped as i'm 6"4 so have gone for a high seat, likewise a high screen. ABS without servos was sharper than my GS. Even got the RDC thrown in for free.
If my ride this afternoon was anything to go by, then I think its going to be a good summer.
Regards.
