The only con with that bike is it still weighs 400 pounds dry, and yes, as the OP found, he might as well get the 1200GS.
i do think that the 1200gs would be a better bike all around then the 800gs, but without the same MPG.
but who cares about MPG's when gas in the USA is cheap
(compared to Europe. the most i paid for a gallon of gas was about $12.00)
