INTRODUCTION
AN IMPORTANT SAFETY MESSAGE:
●
Read this manual, the “PARENTS, YOUNGSTERS AND OFF-HIGHWAY MOTORCYCLES” booklet, and the “TIPS
AND PRACTICE GUIDE FOR THE OFF HIGHWAY MOTORCYCLIST” booklet carefully and completely before operating this motorcycle. Make sure you understand all instructions.
●
Pay close attention to the warning and notice labels on the motorcycle.
●
Never operate a motorcycle without proper training or instruction.
●
Weight of the rider should not exceed 25 kg (55 lb).
AN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you should understand the instructions and warnings in this Owner’s Manual. Then be sure your child understands and will follow them. Also read the “PARENTS, YOUNGSTERS AND OFF-HIGHWAY MOTORCYCLES” and the “TIPS AND PRACTICE GUIDE FOR THE OFF HIGHWAY
MOTORCYCLIST” booklets supplied with this motorcycle when new or available from your Yamaha dealer. Children differ
in skills, physical abilities, and judgment. Some children may not be able to operate a motorcycle safely. Parents should supervise their child’s use of the motorcycle at all times. Parents should permit continued use only if they determine that the
child has the ability to operate the motorcycle safely.
Your motorcycle was delivered with an adjustable speed limiter and power reduction plate. Yamaha recommends that all
beginners start off with the speed limiter adjusting screw turned in and the power reduction plate installed in the exhaust manifold to limit the power available while they learn. The limiter screw may be gradually turned out to increase maximum speed
as the beginner becomes more familiar with operating the motorcycle. Parents should decide when to adjust the motorcycle
for more power as their youngster’s riding skills improve. Once the rider can operate with skill at the top speed permitted by
adjusting the speed limiter alone, the power reduction plate can be removed. Since removal of this plate will result in a significant increase in power, turn the speed limiter back in again; adjust it out in stages as you did before.
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 maintenance requirements in this Owner’s Manual.
INTRODUCTION
●
Obtain qualified training in safe and proper riding techniques.
●

SAFETY INFORMATION
Be a Responsible Owner
As the vehicle’s owner, you are responsible for the safe and proper operation
1
of your motorcycle.
Motorcycles are single-track vehicles.
2
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 maintenance 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.
Safe Riding
Perform the pre-operation checks each
EAU40933
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 for
off-road use only, therefore, it is illegal to operate it on public streets,
roads, or highways, even a dirt or
gravel one. Off-road use on public
lands may be illegal. Please check
local regulations before riding.
●
This motorcycle is designed to carry the operator only. No passengers.
●
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.
2-1
●
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.
●
Many accidents involve inexperienced operators.
●
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 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 under-
SAFETY INFORMATION
cornering (insufficient lean angle
for the speed). Never travel faster
than warranted by conditions.
●
Ride cautiously in unfamiliar areas. You may encounter hidden
obstacles that could cause an accident.
●
The posture of the operator 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.
●
Never ride under the influence of
alcohol or other drugs.
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.
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.
●
Do not run engine in poorly ventilated 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.
Loading
Adding accessories 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 accessories to

SAFETY INFORMATION
your motorcycle. Use extra care when
riding a motorcycle that has added accessories. Here are some general
guidelines to follow if adding accesso-
1
ries to your motorcycle:
Operation of an overloaded vehicle
2
could cause an accident.
●
The weight of the operator must
not exceed 25 kg (55 lb).
●
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 are securely attached to
the motorcycle before riding.
Check accessory mounts 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.
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.
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 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.
●
Accessories fitted to the handlebar or the front fork area can
create instability due to improper
weight distribution. If accesso-
2-3
SAFETY INFORMATION
ries 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. Wind may attempt to lift the motorcycle, or
the motorcycle may become unstable in cross winds.
●
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 electrical 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.

EWA10881
WARNING
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

Recommended fuel:
UNLEADED GASOLINE ONLY
Fuel tank capacity:
2.0 L (0.53 US gal, 0.44 Imp.gal)
Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
gasoline of a different brand 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 con-
tent 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.
