I have been on two long trips with my GF in the mountains, with two 36L sidecases and a 46L topcase, the 650 has more than enough power to feel very sporty, uphill, downhill, whatever. I would imagine the 1000 is even more so.
Also I would add that with a backrest of some kind for the passenger, she can scoot back and you won't even know she's there. PLenty of room. I am about your size, maybe 15-20lbs heavier, and my GF is 5'4" 125. Your passenger will probably really want a backrest, because her seat is flat and a little bit slick.
