Don't need mirror smooth roads to get the best out of a sports bike. All the modern sportsbikes have fully adjustable suspension which can be set up for the type of road or the style of riding. Admittedly not quite as easy as the Gs but if you know what its about it isn't too difficult. As for out accelerating sports bikes out of corners, no problem. The sports bike however is likely to have carried much more corner speed.
Having said all that I think the 1200 Gs is the best all round bike I've ridden, and at this moment can't think of a bike I'd rather own.
