Green Motorcycles

Supposedly, a green painted motorcycle is bad luck. The legend has it that the Harleys used in World War II were often sitting duck targets, and many military riders got their butts blasted off them. And since they were painted Army green, it eventually translated into modern folklore.

those were harleys ...they used to carry important documents and if you were spotted they would shoot you and steal your paperwork/info.

so since you are getting a kawasaki you should be safe...green is kawasaki's color.
