SAFETY INFORMATION
Be a Responsible Owner
As the vehicle’s owner, you are respon-
sible for the safe and proper operation
2
of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are dependent 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.
EAU10283
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 car-
ry the operator and a passenger.
● The failure of motorists to detect
and recognize motorcycles in traffic 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 appears to
be very effective in reducing 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 intersections 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 operators who have been involved in
accidents do not even have a current motorcycle license.
• Make sure that you are qualified
and that you only lend your motorcycle to other qualified operators.
• Know your skills and limits.
Staying within your limits may
help you to avoid an accident.
• We recommend that you practice riding your motorcycle
where there is no traffic until you
have become thoroughly familiar with the motorcycle and all of
its controls.
● Many accidents have been caused
by error of the motorcycle operator. A typical error made by the operator is veering wide on a turn
SAFETY INFORMATION
due to excessive speed or undercornering (insufficient lean angle
for the speed).
• 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 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.
● This motorcycle is designed for on-
road use only. It is not suitable for
off-road use.
Protective apparel
The majority of fatalities from motorcycle accidents are the result of head injuries. The use of a safety helmet is the
single most critical factor in the prevention 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 abrasions
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 system become very hot during or after operation and can cause burns.
2-2
● A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing carbon monoxide can cause headaches,
dizziness, drowsiness, nausea, confusion, and eventually death.
Carbon Monoxide is a colorless, odorless, 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 poisoning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.
● Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rapidly reach dangerous levels.
2
SAFETY INFORMATION
● Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or carports.
● Do not run engine outdoors where
2
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 stability and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use extreme 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 vehicle
could cause an accident.
Maximum load:
185 kg (408 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. Securely pack your heaviest items as
close to the center of the vehicle as
possible and make sure to distribute the weight as evenly as possible on both sides of the motorcycle
to minimize imbalance or instability.
● Shifting weights can create a sud-
den imbalance. Make sure that accessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
• Properly adjust the suspension
for your load (suspension-adjustable models only), 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
2-3
items, including such cargo as
sleeping bags, duffel bags, or
tents, can create unstable handling or a slow steering response.
● 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 available 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 accessories 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 endorse nor recommend the use of accessories not sold by Yamaha or
modifications not specifically recommended by Yamaha, even if sold and
installed by a Yamaha dealer.
SAFETY INFORMATION
Aftermarket Parts, Accessories, and
Modifications
While you may find aftermarket products similar in design and quality to
genuine Yamaha accessories, recognize that some aftermarket accessories
or modifications are not suitable because 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 performance of your motorcycle. Carefully 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 obscure lights or reflectors.
• Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution or aerodynamic 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 aerodynamic effects. Wind may attempt to lift the motorcycle, or
the motorcycle may become unstable in cross winds. These accessories may also cause
instability when passing or being
passed by large vehicles.
• Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the freedom 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 accessories 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 the
performance capabilities and to provide
the best combination of handling, braking, and comfort. Other tires, rims, sizes, and combinations may not be
appropriate. Refer to page 7-17 for tire
specifications and more information on
replacing your tires.

WARNING
The vehicle must not be ridden with
the sidestand down, or if the sidestand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the responsibility of raising the sidestand before starting off. Therefore, check
this system regularly as described
