To get the full top-end potential for freway riding, you'll need a JCosta variator and an upjet. Details for performance improvement can be found at totalruckus in the BR forum.
Some have noted, as I did, that to force more airflow through the cooling channels and keep the temp light off at freeway speeds, you'll need airscoop "extenders", either fabbed or a set of the Honda-made add-ons; the latter are hard to find and expensive, but work quite well.
You will find yourself going faster than you would have thought possible, and for very long distances - the efficiency of the brakes will be a concern.
As to the price for this one: it's good. That's what I sold my '06 for, and it was not in as good shape.
