Interesting points one and all. I was referring to, of course, the EXPANSION caused by heating of the subatomic particles creating the extra space filled with oversized atomic structures [not empty space in the nucleus as some morons believe] thus creating extra weigh and width from the darker color. For much in the same way as water weight is reduced as it is seperated into steam particles, also the reverse is true when expanding a Black Busa. That coupled with the heat against cold fairing against wind that creates a 'Thunder like' effect at air-wind speed over 120 maximum velocity not including any prevailing winds from the surrounding environment. Using a neutral silver/grey elimintates most of all of these unwanted slowing effects. Suzuki knows better than to use white which creates a static discharge from the reflective surfaces due to rejecting the bombardment of various rays [gamma, x, UV etc] which, although brilliant in tests [similar to the DeLorian hitting 88mph in Back to the Future movie], produces ignition of gas, oils, and certain combinations of plastic and rubber used through out the vehicle, thus putting the test pilot in the hospitle for weeks. He's doing much better now.
In clonclusion, Silver = Fastest
Supporting hypothisises can be found in the MIT card catalog of R&D called "Combustion experiments of Motorcyle particles at Terminal Velocity or Why we shouldn't make cycles that can exceed 120mph" 3rd floor Library room 11.
But the pic is great BTW!!
