If I were to go DS, my main concern is handling and that the nimble feeling of my F6B ( yes I mentioned nimble and a Gold Wing in the same sentence ...lol ) is not affected. I really enjoy the ability to toss this big bike back and forth in the twisties and don't want that to be compromised. I know that DS on my Valkyrie does affect it adversly ,in my opinion, this way. So what kind of life/mileage are we talking about?
