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 motorcy-
cle.
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.

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 pre-
vention 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 ac-
cident.
●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 pre-
sent 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 car-
bon monoxide can linger for hours or
days in enclosed or poorly ventilated ar-
eas. If you experience any symptoms of
carbon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.
●Do not run engine indoors. Even if
you try to ventilate engine ex-
haust with fans or open windows
and doors, carbon monoxide can
rapidly reach dangerous levels.
●Do not run engine in poorly ventilat-
ed or partially enclosed areas such
as barns, garages, or carports.
●Do not run engine outdoors where
engine exhaust can be drawn into
a building through openings such
as windows and doors.

SAFETY INFORMATION
Loading
Adding accessories or cargo to your
motorcycle can adversely affect stabil-
ity and handling if the weight distribu-
tion of the motorcycle is changed. To
avoid the possibility of an accident,
use extreme caution when adding car-
go or accessories to your motorcycle.
Use extra care when riding a motorcy-
cle that has added cargo or acces-
sories. Here, along with the informa-
tion 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
vehicle could cause an accident.

curely pack your heaviest items
as close to the center of the vehi-
cle as possible and make sure to
distribute 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
accessories and cargo are se-
curely attached to the motorcycle
before riding. Check accessory
mounts and cargo restraints fre-
quently.
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 ac-
cessories or offer other modifications
for Yamaha vehicles. Yamaha is not in
a position to test the products that
these aftermarket companies pro-
duce. Therefore, Yamaha can neither
endorse nor recommend the use of
accessories 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 acces-
sories or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
Maximum load:
190 kg (419 lb)
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-

SAFETY INFORMATION
products or having other modifications
performed to your vehicle that change
any of the vehicle's design or opera-
tion characteristics can put you and
others at greater risk of serious injury
or death. You are responsible for in-
juries related to changes in the vehi-
cle.
Keep the following guidelines in mind,
as well as those provided under
"Loading" when mounting acces-
sories.
●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 han-
dlebar 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 aslightweight 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
unstable in cross winds. These
accessories may also cause in-
stability when passing or being
passed by large vehicles.
Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the
freedom of movement of the
operator and may limit control
ability, therefore, such acces-
sories are not recommended.
●Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle's electrical sys-
tem, an electric failure could re-
sult, which could cause a danger-
ous loss of lights or engine power.Aftermarket Tires and Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
7-16 for tire specifications and more
information on replacing your tires.

Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an im-
mobilizer system to help prevent theft
by re-registering codes in the standard
keys. This system consists of the fol-
lowing.
●a code re-registering key (with a
red bow)
●two standard keys (with a black
bow) that can be re-registered
with new codes
●a transponder (which is installed
in the code re-registering key)
●an immobilizer unit
●an ECU
●an immobilizer system indicator
light (See page 4-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to a
Yamaha dealer to have them re-regis-
tered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
ECA11821NOTICE
●DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
new codes in the standard keys
is impossible. The standard keys
can still be used to start the ve-
hicle, however if code re-regis-
tering is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced.
Therefore, it is highly recom-
mended to use either standardkey and keep the code re-regis-
tering key in a safe place.
●Do not submerse any key in water.
●Do not expose any key to exces-
sively high temperatures.
●Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
●Do not place items that transmit
electrical signals close to any key.
●Do not place heavy items on
any key.
●Do not grind any key or alter its
shape.
●Do not disassemble the plastic
part of any key.
●Do not put two keys of any immobi-
lizer system on the same key ring.
●Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle's code re-registering key.
●Keep other immobilizer system
keys away from the main switch
as they may cause signal inter-
ference.
