1K does have a point, unless, the winglets really are creating a superlative venturi effect and simply sucking the heat right out... ???
It is possible, coupled with the very high wind velocity, at super high speeds.
Look at what the supercars of today are doing with air cooling.The brakes,
the engine, and various other parts, are being cooled by funneled air.
The aero technology on this bike is outstanding.
