SAFETY INFORMATION

Be a Responsible Owner
2
As the vehicle’s owner, you are responsible for the safe and proper operation
3
of your motorcycle.
Motorcycles are single-track vehicles.
4
Their safe use and operation are dependent upon the use of proper riding
techniques as well as the expertise of
5
the operator. Every operator should
know the following requirements before
6
riding this motorcycle.
He or she should:
7
Obtain thorough instructions from
a competent source on all aspects
8
of motorcycle operation.
Observe the warnings and mainte-
nance requirements in this Own-
9
10
11
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.
12
Never operate a motorcycle with-
out proper training or instruction.
EAU1028B
Take a training course. Beginners
should receive training from a certified instructor. Contact an authorized motorcycle dealer to find out
about the training courses nearest
you.
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 4-1
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.
1-1
• 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.
• Never maintain a motorcycle
without proper knowledge. Contact an authorized motorcycle
dealer to inform you on basic
motorcycle maintenance. Certain maintenance can only be
carried out by certified staff.
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 prac-
SAFETY INFORMATION
tice 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
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
1-2
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.
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 TREAT-

SAFETY INFORMATION
MENT.
1
Do not run engine indoors. Even if
you try to ventilate engine exhaust
2
with fans or open windows and
doors, carbon monoxide can rap-
3
idly reach dangerous levels.
Do not run engine in poorly venti-
lated or partially enclosed areas
4
such as barns, garages, or carports.
Do not run engine outdoors where
5
engine exhaust can be drawn into
6
7
a building through openings such
as windows and doors.
Loading
Adding accessories or cargo to your
motorcycle can adversely affect stabili-
8
ty and handling if the weight distribution
of the motorcycle is changed. To avoid
9
the possibility of an accident, use extreme caution when adding cargo or
10
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.
11
Here, along with the information about
accessories below, are some general
12
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:
150 kg (331 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-ad-
1-3
justable 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 that these
aftermarket companies produce.
Therefore, Yamaha can neither en-
SAFETY INFORMATION
dorse 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 being
passed by large vehicles.
• Certain accessories can displace the operator from his or
her normal riding position. This
improper position limits the free-
1-4
dom 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 6-14 for tire
specifications and more information on
replacing your tires.
Transporting the Motorcycle
Be sure to observe following instructions before transporting the motorcycle in another vehicle.
Remove all loose items from the
motorcycle.

SAFETY INFORMATION
Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.
Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to prevent movement.
Shift the transmission in gear (for
models with a manual transmission).
Secure the motorcycle with
tie-downs or suitable straps that
are attached to solid parts of the
motorcycle, such as the frame or
upper front fork triple clamp (and
not, for example, to rubber-mounted handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
The suspension should be com-
pressed somewhat by the
tie-downs, if possible, so that the
motorcycle will not bounce excessively during transport.

Fuel
Make sure there is sufficient gasoline in
the tank.
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.
1. Before refueling, turn off the engine and be sure that no one is sitting on the vehicle. Never refuel
while smoking, or while in the vicinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. When
refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank.

EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gasoline with care. Never siphon gasoline by mouth. If you should swallow
some gasoline or inhale a lot of gasoline vapor, or get some gasoline in
your eyes, see your doctor immediately. If gasoline spills on your skin,
wash with soap and water. If gasoline spills on your clothing, change
your clothes.
EAU57690
Recommended fuel:
Regular unleaded gasoline (Gasohol
(E10) acceptable)
Fuel tank capacity:
12.0 L (3.17 US gal, 2.64 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on):
2.2 L (0.58 US gal, 0.48 Imp.gal)
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,
as well as to the exhaust system.
Your Yamaha engine has been designed to use regular unleaded gasoline with a research octane number of
95 or higher. If knocking (or pinging) occurs, use a gasoline of a different brand
3-8
or premium unleaded fuel. Use of unleaded fuel will extend spark plug life
and reduce maintenance costs.
Gasohol
There are two types of gasohol: gasohol containing ethanol and that containing methanol. Gasohol containing
ethanol can be used if the ethanol content does not exceed 10% (E10). Gasohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.

The exhaust system is hot after operation. To prevent a fire hazard or
burns:
Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust sys-
tem has cooled down before doing any maintenance work.
Do not allow the engine to idle

Adjusting the shock absorber assemblies
EWA10211
Always adjust both shock absorber
assemblies equally, otherwise poor
handling and loss of stability may
result.
Each shock absorber assembly is
equipped with a spring preload adjusting ring.
To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.
Adjust the spring preload as follows.
To increase the spring preload and
thereby harden the suspension, turn
the adjusting ring on each shock absorber assembly in direction (a). To decrease the spring preload and thereby
soften the suspension, turn the adjusting ring on each shock absorber assembly in direction (b).
Align the appropriate notch in the adjusting ring with the position indicator
ECA10102
on the shock absorber.

EWA10242
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 and have a
