That's some good riding! I am pretty sure that the camera bike chasing, is also a Gold Wing. Big windshield, you can see the vent in the windshield off to the left side, and that unmistakeable sound of a 6-cylinder.
I've ridden lots of them and them newer Gold wings handle pretty good for such a big beast of a bike. The GL1500's were a fine handler, but these new GL1800's are a very good handling machine.
