WARNING
WARNING
EAU41075
Congratulations on your purchase of the Yamaha PW50/PW50F/PW50F1. This model is the result of Yamaha’s vast experience in the production of fine sporting, touring, and pacesetting racing machines. It represents the high degree of craftsmanship and reliability that have made Yamaha a leader in these fields.
This manual will give you an understanding of the operation, inspection, and basic maintenance of this motorcycle. If you
have any questions concerning the operation or maintenance of your motorcycle, please consult a Yamaha dealer.
The design and manufacture of this Yamaha motorcycle fully comply with the emissions standards for clean air applicable
at the date of manufacture. Yamaha has met these standards without reducing the performance or economy of operation
of the motorcycle. To maintain these high standards, it is important that you and your Yamaha dealer pay close attention
to the recommended maintenance schedules and operating instructions contained within this manual.
Yamaha continually seeks advancements in product design and quality. Therefore, while this manual contains the most current product information available at the time of printing, there may be minor discrepancies between your motorcycle and
this manual. If there is any question concerning this manual, please consult a Yamaha dealer.
Please read this manual carefully and completely before operating this motorcycle.
This motorcycle is designed and manufactured for off-road use only. It is illegal to operate this motorcycle on any
public street, road or highway. Such use is prohibited by law. This motorcycle complies with almost all state offhighway noise level and spark arrester laws and regulations. Please check your local riding laws and regulations
before operating this motorcycle.
EWA10032
EWA14352
AN IMPORTANT SAFETY MESSAGE:
Read this manual 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).

INTRODUCTION
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. 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 is equipped with an adjustable speed limiter and a 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.
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.

SAFETY INFORMATION
Be a Responsible Owner
2
As the vehicle’s owner, you are responsible 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 mainte-
nance requirements in this Owner’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 necessary by mechanical conditions.
EAU4093C
Never operate a motorcycle with-
out proper training or instruction.
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 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.
2-1
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.
• 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.
Page 21
SAFETY INFORMATION
Many accidents involve inexperi-
enced 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 undercornering (insufficient lean angle for the speed). Never travel
faster than warranted by conditions.
Ride cautiously in unfamiliar ar-
eas. You may encounter hidden
obstacles that could cause an accident.
The posture of the operator is im-
portant 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 poi-
2
2-2
Page 22
SAFETY INFORMATION
soning, leave the area immediately, get
fresh air, and SEEK MEDICAL TREATMENT.
2
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 venti-
lated 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
your motorcycle. Use extra care when
riding a motorcycle that has added accessories. Here are some general
guidelines to follow if adding accessories to your motorcycle:
Operation of an overloaded vehicle
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 sud-
den imbalance. Make sure that
accessories are securely attached
to the motorcycle before riding.
Check accessory mounts 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.
2-3
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
Page 23
SAFETY INFORMATION
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 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. 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 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
2-4
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
7-12 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.
Check that the fuel cock is in the
“S” (stop) 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
2
Page 24
SAFETY INFORMATION
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.
2
The suspension should be com-
pressed somewhat by the tiedowns, if possible, so that the motorcycle will not bounce excessively during transport.

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. 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.

Checking the spark plug
The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic maintenance and lubrication chart. In addition, the condition of the spark plug
can reveal the condition of the engine.
To remove the spark plug

To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light
tan (the ideal color when the vehicle is ridden normally).
If the spark plug shows a distinctly different color, the engine could be operating improperly. Do not attempt to
diagnose such problems yourself. Instead, have a Yamaha dealer check
the vehicle.

erosion and excessive carbon or
other deposits, and replace it if
necessary.

2. Start the engine and warm it up for
several minutes at 1000–2000
r/min while occasionally revving it
to 4000–5000 r/min.
The engine is warm when it quickly responds to the throttle.
3. Check the engine idling speed
and, if necessary, adjust it to
specification by turning the throttle stop screw. To increase the engine idling speed, turn the screw in
direction (a). To decrease the engine idling speed, turn the screw in
direction (b).

Tires
Tires are the only contact between the
vehicle and the road. Safety in all conditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA15371
Operation of this vehicle with improper tire pressure may cause severe injury or death from loss of
control.
The tire air pressure must be
checked and adjusted on cold tires
(i.e., when the temperature of the
tires equals the ambient temperature).

Tire information
This model is equipped with tube tires.
Tires age, even if they have not been
used or have only been used occasionally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires shall be
checked by tire specialists to ascertain
their suitability for further use.
The front and rear tires should be of
the same make and design, otherwise the handling characteristics of
7
the vehicle may be different, which
could lead to an accident.
After extensive tests, only the tires listed below have been approved for this
model by Yamaha.

Have a Yamaha dealer replace
excessively worn tires. Operating the motorcycle with excessively worn tires decreases
riding stability and can lead to
loss of control.
The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowledge and experience.
It is not recommended to patch
a punctured tube. If unavoid-
able, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
Ride conservatively after
changing a tire since the tire
must seat itself on the rim properly. Failure to allow proper
seating may cause tire failure,
which may result in damage to
the motorcycle and injury to the
rider.

Troubleshooting
Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting chart
represents a quick and easy procedure
for checking these vital systems yourself. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replacement parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.

Care
While the open design of a motorcycle
reveals the attractiveness of the technology, it also makes it more vulnerable. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go unnoticed on a car, however, it detracts
from the overall appearance of a motorcycle. Frequent and proper care
does not only comply with the terms of
the warranty, but it will also keep your
motorcycle looking good, extend its
life and optimize its performance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and covers as well as all electrical couplers and connectors, including
the spark plug cap, are tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such prod-
ucts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA17111
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If such products are
used on hard-to-remove dirt, do
not leave the cleaner on the affected area any longer than instructed. Also, thoroughly rinse
the area off with water, immedi-
ately dry it, and then apply a cor-
rosion protection spray.
Improper cleaning can damage
plastic parts (such as cowlings,
panels, etc.) and the mufflers.
Use only a soft, clean cloth or
sponge with water to clean
plastic. However, if the plastic
parts cannot be thoroughly
cleaned with water, diluted mild
detergent with water may be
used. Be sure to rinse off any

detergent residue using plenty
of water, as it is harmful to plastic parts.
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust removers or inhibitors, brake fluid,
antifreeze or electrolyte.
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following areas: seals (of wheel and swing-
arm bearings, fork and brakes),
electric components (couplers,
connectors, and switches),
breather hoses and vents.
After normal use
Remove dirt with warm water, a mild
detergent, and a soft, clean sponge,
and then rinse thoroughly with clean
water. Use a toothbrush or bottlebrush
for hard-to-reach areas. Stubborn dirt
and insects will come off more easily if
the area is covered with a wet cloth for
a few minutes before cleaning.
After riding in the rain or near the sea
Since sea salt is extremely corrosive,
carry out the following steps after each
ride in the rain or near the sea.
1. Clean the motorcycle with cold
water and a mild detergent, after
the engine has cooled down.
NOTICE: Do not use warm wa-
ter since it increases the corrosive action of the salt.
[ECA10792]
2. Apply a corrosion protection spray
on all metal, including chromeand nickel-plated, surfaces to prevent corrosion.
After cleaning
1. Dry the motorcycle with a chamois
or an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainlesssteel parts.
3. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal,
including chrome- and nickel-plated, surfaces.
4. Use spray oil as a universal cleaner to remove any remaining dirt.
5. Touch up minor paint damage
caused by stones, etc.
6. Wax all painted surfaces.

Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover. Be
sure the engine and the exhaust system are cool before covering the motorcycle.
ECA10811
Storing the motorcycle in a
poorly ventilated room or covering it with a tarp, while it is still
wet, will allow water and humid-
ity to seep in and cause rust.
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemicals are stored.
Long-term
Before storing your motorcycle for several months:
1. Follow all the instructions in the
“Care” section of this chapter.
8-3
2. For motorcycles equipped with a
fuel cock that has an “S” (stop)
position: Turn the fuel cock lever
to “S”.
3. Drain the carburetor float chamber
by loosening the drain bolt; this
will prevent fuel deposits from
building up. Pour the drained fuel
into the fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap
and spark plug.
b. Pour a teaspoonful of engine
oil into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit sparking during the next step.)
d. Turn the engine over several
times with the starter. (This will

The figures quoted are emission levels
and are not necessarily safe working
levels. Whilst there is a correlation between the emission and exposure levels, this cannot be used reliably to
determine whether or not further precautions are required. Factors that influence the actual level of exposure of
work-force include the characteristics
of the work room, the other sources of
noise, etc. i.e. the number of machines
and other adjacent processes, and the
length of time for which an operator is
exposed to the noise. Also the permissible exposure level can vary from
country. This information, however, will
enable the user of the machine to make
9
a better evaluation of the hazard and
risk.
