I have a copy of Amazon.com: Motorcycle Design and Technology Handbook (Motorbooks Workshop) (9780760319901): Gaetano Cocco: Books
and have found it very useful. One point not commonly made is that down force aids stability. A full body fairing might start as NACA wing profile inverted with a slight negative angle of attack. The shape can be developed as composite ellipsoids using the 3D graph features of a spreadsheet. The lateral Cd and Area determine the effective side forces the wind generates. Seat height may be limited by law as in NYS at 27 inches. Getting the rider a comfortable fit with the motorcycle is important. Wheelbase, fork angle, and trail need to be considered in the setup. A proper Kamm tail will help reduce side loads and make for handy storage compartments.
