9 Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and free-
dom. 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 Ñ more than car drivers Ñ 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 passen-
gers. 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 pro-
tective 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
Ñ avoiding all dangers, including those caused by others.
Enjoy your ride!
