SAFETY INFORMATION
Be a Responsible Owner
As the vehicle’s owner, you are res-
1
ponsible for the safe and proper operation 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 main-
tenance requirements in this
Owner’s Manual.
● Obtain qualified training in safe
and proper riding techniques.
● Obtain professional technical
service as indicated in this
Owner’s Manual and/or when
made necessary 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 4-2 for a list
of pre-operation checks.
● This motorcycle is designed to
carry 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
1-1
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 inexpe-
rienced 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 cau-
sed by error of the motorcycle
operator. A typical error made by
the operator is veering wide on a
SAFETY INFORMATION
turn 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 hel-
met.
● 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.
1-2
● 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.
● 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.
1
SAFETY INFORMATION
● Do not run engine indoors. Even
if you try to ventilate engine
1
exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous
levels.
● Do not run engine in poorly venti-
lated or partially enclosed areas
such as barns, garages, or carports.
● Do not run engine outdoors whe-
re 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:
196 kg (432 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
sudden imbalance. Make sure
that accessories and cargo are
securely attached to the
motorcycle before riding. Check
accessory mounts and cargo restraints frequently.
1-3
• Properly adjust the suspension
for your load (suspensionadjustable 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 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
SAFETY INFORMATION
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.
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 “Loading” 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
1-4
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 operator 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 6-17 for tire specifications and
more information on replacing your
tires.

Sidestand
1. Sidestand
The sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.
TIP
The built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain
situations. (See further down for an
explanation of the ignition circuit cutoff system.)
EWA10240
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
below and have a Yamaha dealer
repair it if it does not function properly.
EAU15314
Ignition circuit cut-off system
The ignition circuit cut-off system
(comprising the sidestand switch,
clutch switch and neutral switch) has
the following functions.
● It prevents starting when the
transmission is in gear and the

lever is not pulled.
● It prevents starting when the
transmission is in gear and the
clutch lever is pulled, but the
sidestand is still down.
● It cuts the running engine when
the transmission is in gear and
the sidestand is moved down.
Periodically check the operation of
the ignition circuit cut-off system
according to the following procedure.
TIP
This check is most reliable if performed with a warmed-up engine.
