GIVE SAFETY THE RIGHT OF WAY
Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and
freedom. However, they also impose certain limits, which you must accept; even the best motorcycle
does not ignore the laws of physics.
Regular care and maintenance are essential for preserving value and operating condition of your
motorcycle. Moreover, what is true for the motorcycle is also true for the rider: good performance
depends on being in good shape. Riding under the influence of medication, drugs and alcohol is, of
course, out of the question. Motorcycle riders—more than car drivers—must always be at their mental
and physical best. Under the influence of even small amounts of alcohol, there is a tendency to take
dangerous risks.
Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and
passengers. Always wear a complete motorcycle suit (whether made of leather or tear-resistant
synthetic materials with protectors), sturdy boots, motorcycle gloves and a properly fitting helmet.
Optimum protective wear, however, should not encourage carelessness. Although full-coverage
helmets and suits, in particular, create an illusion of total safety and protection, motorcyclists will
always be vulnerable. Riders who lack critical self-control run the risk of going too fast and are apt to
take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely,
predictably and defensively—avoiding all dangers, including those caused by others.
Enjoy your ride!
