I think it would be a beautiful weight drop from the 1200.. my goodness that bike is a tank. But incredibly agile and nimble once you get used to throwing that weight around. Except when once I slid fully loaded into a deep muddy ravine in the French Alps.. took me a good 4 hours to drag 630 lbs of bike out a few inches at a time. I thought I was going to die on that mountain.
The GS800 would be perfect for me for the city.
