SAFETY INFORMATION
• Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
●The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator
footrests during operation to
maintain control of the motor-
cycle.
• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep
both feet on the passenger
footrests.
• Never carry a passenger un-
less he or she can firmly place
both feet on the passenger
footrests.
●Never ride under the influence of
alcohol or other drugs.
●This motorcycle is designed for
on-road use only. It is not suitable
for off-road use.
Protective apparel
The majority of fatalities from motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is
the single most critical factor in the
prevention or reduction of head in-
juries.
●Always wear an approved helmet.
●Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impairment
of vision that could delay seeing a
hazard.
●The use of a jacket, heavy boots,
trousers, gloves, etc., is effective
in preventing or reducing abra-
sions or lacerations.
●Never wear loose-fitting clothes,
otherwise they could catch on the
control levers, footrests, or
wheels and cause injury or an ac-
cident.
●Never touch the engine or ex-
haust system during or after oper-
ation. They become very hot and
can cause burns. Always wear
protective clothing that covers
your legs, ankles, and feet.
●A passenger should also observe
the above precautions.
Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the re-
moval of original equipment, may ren-
der the motorcycle unsafe for use and
may cause severe personal injury.
Modifications may also make your mo-
torcycle illegal to use.
Loading and accessories
Adding accessories or cargo to your
motorcycle can adversely affect stabili-
ty and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use ex-
treme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.

PRE-OPERATION CHECKS
4-1
EAU15591
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpected-
ly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage
or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough vi-
sual inspection, to check the following points before each ride.
NOTE:
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very
short time; and the added safety it assures is more than worth the time involved.
EWA11150
WARNING0
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operat-
ing the vehicle.

PERIODIC MAINTENANCE AND MINOR REPAIR
EAU17240
Safety is an obligation of the owner.
Periodic inspection, adjustment and
lubrication will keep your vehicle in the
safest and most efficient condition
possible. The most important points of
inspection, adjustment, and lubrica-
tion are explained on the following
pages.
The intervals given in the periodic
maintenance and lubrication chart
should be simply considered as a gen-
eral guide under normal riding condi-
tions. However, DEPENDING ON
THE WEATHER, TERRAIN, GEO-
GRAPHICAL LOCATION, AND INDI-
VIDUAL USE, THE MAINTENANCE
INTERVALS MAY NEED TO BE
SHORTENED.
EWA10320
WARNING0
If you are not familiar with motorcy-
cle maintenance work, have a
Yamaha dealer do it for you.

any spark plug to slowly erode, the
spark plug should be removed and
checked in accordance with the peri-
odic maintenance and lubrication
chart. In addition, the condition of the

●Adjust the suspension and tire
air pressure with regard to the
load.
●Check the tire condition and air
pressure before each ride.Tire inspection
1. Tire sidewall
2. Tire tread depth
The tires must be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or if
the sidewall is cracked, have a Yama-
ha dealer replace the tire immediately.
NOTE:
The tire tread depth limits may differ
from country to country. Always com-
ply with the local regulations.
EWA10470
WARNING0
●Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the ve-
hicle with excessively worn
tires decreases riding stability
and can lead to loss of control.
●The replacement of all wheel
and brake related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.
