There is no doubt that the majority of touring owners are happy with the handling of their bike, no matter what model year it is. For reasons that are not clear there is a small proportion of owners who are NOT happy. I was one and fitted a True-Track kit to my Glide and also my Dyna. My Buell doesn't need one, because it has three handling stabilizers, just as recent Sportsters do. If Harley had fitted all their rubber-mount bikes with three stabilizers, we would not be discussing this subject so often, and True-Track would probably not exist in the form we know them.
The rubber-mount system of the 09 and later bikes is an improvement over the previous bikes, but still fails to address the problem 'mile high king' pointed out, which is the rubber mountings are unsupported. It is an engineering folly, just as the previous bikes were! The only certain thing about the latest bikes is that fewer owners than previously will find their bikes' handing could be better.
The few of us who own both a Buell and a touring Harley can be smug in the knowledge that we know the way ahead, as far as the Harley is concerned! Three stabilizers good, less than three bad!
