Wonder how well a radar gun works against it?
The parabolic reflectors in the headlights are the main reflectors of radar. An actual test by Motorcyclist magazine many years ago showed that big Harleys with tiny chopper headlamps were harder to detect than much smaller bullet bikes with those big dual headlamps. The results were consistent. The more the area of headlamp reflectors the further away the bikes could be detected. The physical sizes of the bikes’ frontal areas had no effect.
