2020? Pretty sure the world is going to end in 2012... Least that's what the Whack jobs, Wing Nuts, and Tin Foil Hat wearers are saying... I'd Aim for 2012.
My only input would be:
-Alternative Fuels, electric would be cool, hydrogen fuel cell maybe?
-Advanced polymers and composites.
-Integrated Rider Information System. IRIS, some sort of HUD inside the riders helmet, or a completely immersive holographic projection system. Integrating rear view, GPS, speed, bike data, and a FLIR system for enhanced all weather/day or night vision.
-Anti lock brakes, defeatable adjustable traction control.
-Resilient self healing Nano Body work. User Selectable colors, and patterns.
-Maybe even active aero reconfigurable on the fly or as conditions permit. A bike that adapts not only suspension setting but shape to accommodate different environs or speeds.
- Or hell, the entire body serves as a solar collector for the electric powered Busa...
Otherwise for the Love of god, make sure that the Busa isn't still ugly. I love my Busa, but it is just getting uglier with each new iteration. We can say it looks that way for a reason, and I say yeah, cause the designer went to a Public School....
Please, Please let the 2020 Busa finally be sexy.
