INTRODUCTION
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

WARNING
PLEASE READ THIS MANUAL CAREFULLY AND COMPLETELY BEFORE OPERATING THIS MOTORCYCLE.
EWA14350
WARNING
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 OFF-HIGHWAY NOISE LEVEL AND SPARK ARRESTER
LAWS AND REGULATIONS. PLEASE CHECK YOUR LOCAL RIDING LAWS AND REGULATIONS BEFORE OPERATING THIS MOTORCYCLE.
*Product and specifications are subject to change without notice.
Always make pre-operation
checks. Careful checks may help
prevent an accident.
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.
Many accidents involve inexperienced operators.
●
Make sure that the operator is
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.
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 un-
dercornering (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
1-1
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.
●
Never touch the engine or exhaust
system during or after operation.
They become very hot and can
cause burns. Always wear protective clothing that covers your legs,
ankles, and feet.
Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the removal of original equipment, may render the motorcycle unsafe for use and
may cause severe personal injury.
Modifications may also make your motorcycle illegal to use.
Loading and accessories
Adding accessories to your motorcycle
Page 13
SAFETY INFORMATION
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:
Loading
●
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. 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.
●
Never attach any large or heavy
items to the handlebar, front fork,
or front fender.
Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this motorcycle. Since Yamaha cannot
test all other accessories that may be
available, you must personally be responsible for the proper selection, installation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any accessories.
Keep these guidelines in mind for
mounting accessories in addition to
those provided under “Loading”.
●
Never install accessories or 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 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.
●
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
1

SAFETY INFORMATION
engine power.
Gasoline and exhaust gas
●
GASOLINE IS HIGHLY FLAMMA-
1
BLE:
●
Always turn the engine off when
refueling.
●
Take care not to spill any gaso-
line on the engine or exhaust
pipe/muffler when refueling.
●
Never refuel while smoking or in
the vicinity of an open flame.
●
Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poisonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has adequate ventilation.
●
Always turn the engine off before
leaving the motorcycle unattended. When parking the motorcycle,
note the following:
●
The engine and exhaust pipe/
muffler may be hot, therefore,
park the motorcycle in a place
where pedestrians or children
are not likely to touch these hot
areas.
●
Do not park the motorcycle on a
slope or soft ground, otherwise it
may fall over.
●
Do not park the motorcycle near
a flammable source (e.g., a kerosene heater, or near an open
flame), otherwise it could catch
fire.
●
When transporting the motorcycle
in another vehicle, make sure that
it is kept upright and that the fuel
cock is turned to “S” (stop). If the
motorcycle should lean over, gasoline may leak out of the carburetor or fuel tank.
●
If you should swallow any gasoline, inhale a lot of gasoline vapor,
or allow gasoline to get into your
eyes, see your doctor immediately. If any gasoline spills on your
skin or clothing, immediately wash
the affected area with soap and
water and change your clothes.

PRE-OPERATION CHECKS
The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
1
tion, to check the following points before each ride.
NOTE:
2
Pre-operation checks should be made each time the vehicle is used. Such an inspection can be accomplished in a very short
time; and the added safety it assures is more than worth the time involved.

Engine break-in
There is never a more important period
in the life of your engine than the first 5
hours of riding. It is also important to accustom the rider to the motorcycle during this time. Please read the following
information carefully.
Since the engine is brand new, do not
put an excessive load on it for the first 5
hours of operation. The various parts in
the engine wear and polish themselves
to the correct operating clearances.
During this period, prolonged full-throttle operation or any condition that might
result in engine overheating must be
avoided. However, momentary
full-throttle operation under load (i.e.,
two to three seconds maximum) does
not harm the engine. Each full-throttle
acceleration should be followed with a
substantial rest period for the engine.
To allow the engine to cool down from
the temporary buildup of heat, cruise at
a lower engine speed.
After the first 5 hours of operation, thoroughly check the motorcycle for loose
parts, oil leakage and any other problems. Be sure to inspect and make ad-
5-3
justments thoroughly, especially
cables. In addition, check all fittings and
fasteners for looseness, and tighten if
necessary.
ECA10270
CAUTION:
If any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.

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.

Matte color caution
ECA15192
CAUTION:
Some models are equipped with
matte colored finished parts. Be
sure to consult a Yamaha dealer for
advice on what products to use before cleaning the vehicle. Using a
brush, harsh chemical products or
cleaning compounds when cleaning
these parts will scratch or damage
their surface. Wax also should not
be applied to any matte colored finished parts.
EAU40632
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-
7-1
ucts onto seals, gaskets and wheel
axles. Always rinse the dirt and degreaser off with water.
Cleaning
CAUTION:
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, immediately dry it, and then apply a corrosion protection spray.
Improper cleaning can damage
●
plastic parts such as cowlings,
panels, windshields, headlight
lenses, meter lenses, etc. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
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

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.
ECA10790
CAUTION:
Do not use warm water since it increases the corrosive action of the
salt.
2. Apply a corrosion protection spray
on all metal, including chrome- and
nickel-plated, surfaces to prevent
corrosion.
washing.
After cleaning
1. Dry the motorcycle with a chamois
or an absorbing cloth.
2. Use a chrome polish to shine
chrome, aluminum and stainless-steel parts, including the exhaust system. (Even the thermally
induced discoloring of stainless-steel exhaust systems can be
removed through polishing.)
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.
7. Let the motorcycle dry completely
before storing or covering it.
WARNING
●
Make sure that there is no oil or
wax on the tires.

CAUTION:
●
Apply spray oil and wax sparingly and make sure to wipe off
any excess.
●
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care

Storage
Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
CAUTION:
Storing the motorcycle in a
●
poorly ventilated room or covering it with a tarp, while it is still
wet, will allow water and humidity 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.
2. For motorcycles equipped with a
fuel cock that has an “S” (stop) position: Turn the fuel cock lever to
ECA10810
“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
coat the cylinder wall with oil.)
e. Remove the spark plug cap
from the spark plug, and then

3
pivoting points of all levers and
pedals as well as of the center-
4
stand.
7. Check and, if necessary, correct
5
the tire air pressure, and then lift
the motorcycle so that both of its
6
wheels are off the ground. Alternatively, turn the wheels a little every
month in order to prevent the tires

from becoming degraded in one
spot.
8. Cover the muffler outlet with a
