Excellent info from Aerohead shows that Kamming the tail starts a big loss at anything more than 10% of the airfoil length. He has shown that even a very short fineness airfoil is much better than a long airfoil Kammed at 40%. And a round nosed cone with straight sides is fairly poor also compared to even a much shorter airfoil. We need to make room for the license plate. I would shape the side view to match the aero template starting just in front of the front wheel, truncating at the back. And make the top view as a non truncated short airfoil along the bottom of the bike, tapering up to a 9 inch wide Kamm at the top of the tail for added storage, and a place to mount the license plate and rear flush mount led turn signals.
