9 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 your motorcycle’s value and operat-
ing condition. Moreover, what is true for the motorcycle is also true for the rider: good perfor-
mance 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 hel-
met. Optimum protective wear, however, should not encourage carelessness. Though full-cov-
erage helmets and suits, in particular, create an illusion of total safety and protection, motorcy-
clists 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 motor-
cyclist rides safely, predictably and defensively - avoiding all dangers, including those caused
by others.
Enjoy your ride!

Periodic inspection, adjustment
and lubrication will keep your
motorcycle in the safest and most
efficient condition possible. Safety
is an obligation of the motorcycle
owner. The maintenance and lubri-
cation schedule chart should be
considered strictly as a guide to
general maintenance and lubrica-
tion intervals. YOU MUST TAKE
INTO CONSIDERATION THAT
WEATHER, TERRAIN, GEOGRAPHI-
CAL LOCATIONS, AND A VARIETY
OF INDIVIDUAL USES ALL TEND
TO DEMAND THAT EACH OWNER
ALTER THIS TIME SCHEDULE TO
SHORTER INTERVALS TO MATCH
THE ENVIRONMENT. The most
important points of motorcycle
inspection, adjustment, and lubri-
cation are explained in the follow-
ing pages.

Tool kit
The tool kit is located behind panel
B. (See page 6-7 for panel removal
and installation procedures.) The
tools provided in the owner’s tool kit
are to assist you in the performance
of periodic maintenance. However,
some other tools such as a torque
wrench are also necessary to per-
form the maintenance correctly.
The service information included in
this manual is intended to provide
you, the owner, with the necessary
information for completing some of
your own preventive maintenance
and minor repairs.
