I got a quick ride in Dan's amazing new 28 yesterday and it's incredibly quick from 50-110mph. We ran out of water so he had to get out of the throttles. It feels perfectly balanced and my opinion, which isn't worth much, 400s would be too heavy. The windshield is a lil too low for me. It's a badass ride.
Now that I see the layout with the GPS please allow me my humble opinion. I would like to see the GPS inset into the center of the dash verses where it is at. Seems like it is at too much of an angle to make it out in certain conditions. Also putting it into that upper pad takes away the clean lines and takes away from driver visibility.
