     In the U. S. ,the public has tended to believe that all motorcycles are ridden by wild,irresponsible

lawless young men.

     There are several things about motorcycling that the average citizen dislikes. A cyclist's appearance

has something to do with this dislike. Motorcyclists frequently look dirty;in fact,they are dirty. 0n the

road there is little to protect them from mud,crushed insects and bird droppings. For practical reasons

they are often dressed in old clothing which looks much less respectable than the clothing of people who

  ride in cars. For the same reason motorcyclists usually wear dark colors. Perhaps this helps to explain

why they are sometimes suspected of having evil natures. In old plays of long ago,evil characters usually

wore black. In cowboy movies the "bad guys" usually wear black hats while the "good guys" wear lighter

colors.

Something else about their appearance makes an unfavorable impression.  In their practical,protective

clothing they look very much like the men on military motorcycles in the movies of World War II-cruel

enemies who roared into peaceful villages filling people's hearts with fear.

     Probably the machine itself also produces anger and fear.  Motorcycles are noisy,though some big

trucks are even noisier. But trucks are big and carry heavy loads;they are accepted(if not really

welcomed)because they perform a needed service,making America move. Motorcycles,on the other

hand,make all unpleasant noise just to give their riders pleasure. That is what is commonly thought. In the

woods motorcycles,frighten animals. Roaring along quiet streets, they wake sleeping families and make

babies cry.

     Of course the danger of motorcycling,also helps account for many people's low opinion of the sport.

Its defenders, however,claim that careful cyclists are in less danger than commonly behaved.

     A cyclist must drive as if everybody around him wanted to kill him. He must pay careful attention to

his driving. From that point of view,a man on a motorcycle is safer than,a man in a car.
