Motorcycles are fascinating vehicles, which
can give you an unsurpassed feeling of
power and freedom. However, they also
impose certain limits, which you must ac-
cept; even the best motorcycle does not ig-
nore the laws of physics.
Regular care and maintenance are essen-
tial for preserving your motorcycle’s value
and operating condition. 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 rid-
ers - more than car drivers - must always
be at their mental and physical best. Under
the influence of even small amounts of al-
cohol, there is a tendency to take danger-
ous 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 materi-
als with protectors), sturdy boots, motorcy-
cle gloves and a properly fitting helmet.
Optimum protective wear, however, should
not encourage carelessness. Though full-
coverage helmets and suits, in particular,
create an illusion of total safety and protec-
tion, motorcyclists will always be vulnera-
ble. 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!
