We've covered this before, but to summarize, some believe that green motorcycles are bad luck. (Clearly, nobody's mentioned this to Kawasaki.) The belief likely goes back to World War II. Messengers and scouts often rode army motorcycles, painted green, and were often targets for snipers and sharpshooters. Causation does not equal correlation, however. Another theory is that after the war, many army surplus bikes were sold to the general public. These were not always in the best state of repair when their new owners began to ride them, leading to unfortunate consequences. Needless to say, Kawasaki has proven that green bikes are not all bad, and are actually quite good..
