EAU10313
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements before
riding this motorcycle.
He or she should:
●Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.
●Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.
●Obtain qualified training in safe
and proper riding techniques.
●Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.
Safe Riding
Perform the pre-operation checks each
time you use the vehicle to make sure it
is in safe operating condition. Failure to
inspect or maintain the vehicle properly
increases the possibility of an accident
or equipment damage. See page 5-1
for a list of pre-operation checks.
●This motorcycle is designed to
carry the operator and a passen-
ger.
●The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been
caused by an automobile driver
who did not see the motorcycle.
Making yourself conspicuous ap-
pears to be very effective in reduc-
ing the chance of this type of
accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you are
approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.
• Ride where other motorists can
see you. Avoid riding in another
motorist’s blind spot.
●Many accidents involve inexperi-
enced operators. In fact, many op-
erators who have been involved in
accidents do not even have a cur-
rent motorcycle license.
• Make sure that you are qualified
and that you only lend your mo-
torcycle to other qualified opera-
tors.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you prac-
tice riding your motorcycle
where there is no traffic until you
have become thoroughly famil-
iar with the motorcycle and all of
its controls.
●Many accidents have been
caused by error of the motorcycle
operator. A typical error made by
5P0_F8199_E1.book Page 1 Thursday, January 15, 2009 1:10 PM

SAFETY INFORMATION

the operator is veering wide on a
turn due to excessive speed or un-
dercornering (insufficient lean an-
gle for the speed).
• Always obey the speed limit and
never travel faster than warrant-
ed by road and traffic condi-
tions.
• 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 foot-
rests during operation to main-
tain control of the motorcycle.
• 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 unless
he or she can firmly place both
feet on the passenger footrests.
●Never ride under the influence of
alcohol or other drugs.
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 preven-
tion or reduction of head injuries.
●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 accident.
●Always wear protective clothing
that covers your legs, ankles, and
feet. The engine or exhaust sys-
tem become very hot during or af-
ter operation and can cause
burns.
●A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing car-
bon monoxide can cause headaches,
dizziness, drowsiness, nausea, confu-
sion, and eventually death.
Carbon Monoxide is a colorless, odor-
less, tasteless gas which may be
present even if you do not see or smell
any engine exhaust. Deadly levels of
carbon monoxide can collect rapidly
and you can quickly be overcome and
unable to save yourself. Also, deadly
levels of carbon monoxide can linger
for hours or days in enclosed or poorly
ventilated areas. If you experience any
symptoms of carbon monoxide poison-
ing, leave the area immediately, get
fresh air, and SEEK MEDICAL TREAT-
MENT.

SAFETY INFORMATION

●Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly reach dangerous levels.
●Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or car-
ports.
●Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.
Loading
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.
Here, along with the information about
accessories below, are some general
guidelines to follow if loading cargo to
your motorcycle:
The total weight of the operator,
passenger, accessories and cargo
must not exceed the maximum load
limit. Operation of an overloaded ve-
hicle could cause an accident.
When loading within this weight limit,
keep the following in mind:
●Cargo and accessory weight
should be kept as low and close to
the motorcycle as possible. Se-
curely pack your heaviest items as
close to the center of the vehicle
as possible and make sure to dis-
tribute the weight as evenly as
possible on both sides of the mo-
torcycle to minimize imbalance or
instability.
●Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
• Properly adjust the suspension
for your load, and check the
condition and pressure of your
tires.
• Never attach any large or heavy
items to the handlebar, front
fork, or front fender. These
items, including such cargo as
sleeping bags, duffel bags, or
tents, can create unstable han-
dling or a slow steering re-
sponse.
●This vehicle is not designed to
pull a trailer or to be attached to
a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avail-
able only from a Yamaha dealer, have
been designed, tested, and approved
by Yamaha for use on your vehicle.

Many companies with no connection to
Yamaha manufacture parts and acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-
dorse nor recommend the use of ac-
cessories not sold by Yamaha or
modifications not specifically recom-
mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories, and
Modifications
While you may find aftermarket prod-
ucts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accessories
or modifications are not suitable be-
cause of potential safety hazards to
you or others. Installing aftermarket
products or having other modifications
performed to your vehicle that change
any of the vehicle’s design or operation
characteristics can put you and others
at greater risk of serious injury or death.
You are responsible for injuries related
to changes in the vehicle.
Keep the following guidelines in mind,
as well as those provided under “Load-
ing” when mounting accessories.
●Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. Care-
fully inspect the accessory before
using it to make sure that it does
not in any way reduce ground
clearance or cornering clearance,
limit suspension travel, steering
travel or control operation, or ob-
scure lights or reflectors.
• Accessories fitted to the handle-
bar or the front fork area can
create instability due to improp-
er weight distribution or aerody-
namic changes. If accessories
are added to the handlebar or
front fork area, they must be as
lightweight as possible and
should be kept to a minimum.
• Bulky or large accessories may
seriously affect the stability of
the motorcycle due to aerody-
namic effects. Wind may at-
tempt to lift the motorcycle, or
the motorcycle may become un-
stable in cross winds. These ac-
cessories may also cause
instability when passing or be-
ing passed by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the free-
dom of movement of the opera-
tor and may limit control ability,
therefore, such accessories are
not recommended.
●Use caution when adding electri-
cal accessories. If electrical acces-
sories exceed the capacity of the
motorcycle’s electrical system, an
electric failure could result, which
could cause a dangerous loss of
lights or engine power.
Aftermarket Tires and Rims
The tires and rims that came with your
motorcycle were designed to match

provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
7-18 for tire specifications and more
information on replacing your tires.

Helmets
Operating this vehicle without an ap-
proved motorcycle helmet increases
your chances of a severe head injury or
death in the event of an accident. The
majority of fatalities from motorcycle or
scooter accidents are the result of head
injuries. The use of a safety helmet is
the single most critical factor in the pre-
vention or reduction of head injuries.
Always select an approved
motorcycle helmet
Pay attention to the following when
choosing a motorcycle helmet.
●The helmet must meet the safety
standard “TIS”.
●The helmet size must match the
size of the rider’s head.
●Never subject a helmet to heavy
shocks. Wearing the helmet correctly
Always connect the chin strap. In the
case of an accident, the helmet has a
much less chance of coming off if the
chin strap is connected.
