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.
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 car-
ry the operator only. No passengers.
● Many accidents involve inexperi-
enced 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-
EAU41460
dercornering (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.
● Be sure the transmission is in neu-
tral before starting the engine.
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.
● 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.

SAFETY INFORMATION
Loading and accessories
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:
Loading
● 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 sud-
den 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
1-2
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 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
engine power.

SAFETY INFORMATION
Gasoline and exhaust gas
● GASOLINE IS HIGHLY FLAMMA-
BLE:
1
• Be sure to always use a fresh
mixture of oil and gasoline.
• Always turn the engine off when
refueling.
• Take care not to spill any gasoline 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 “OFF”. If the
motorcycle should lean over, gasoline may leak out of the carburetor or fuel tank.
● If you should swallow any gaso-
line, 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 inspection, to check the following points before each ride.
NOTE:
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.

WARNING
If any item in the Pre-operation check list is not working properly, have it inspected and repaired before operating
the vehicle.

excessively worn tires. Operating the motorcycle with exces-
sively worn tires decreases
riding stability and can lead to
loss of control.
● The replacement of all wheel-
and brake-related parts, including 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 unavoidable, however, patch the tube
very carefully and replace it as

Spoke wheels
To maximize the performance, durability, and safe operation of your motorcycle, note the following points
regarding the specified wheels.
● The wheel rims should be checked
for cracks, bends or warpage, and
the spokes for looseness or damage before each ride. If any damage is found, have a Yamaha
dealer replace the wheel. Do not
attempt even the smallest repair to
the wheel. A deformed or cracked
wheel must be replaced.
● The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse handling characteristics, and a shortened tire life.
● Ride at moderate speeds after
changing a tire since the tire surface must first be “broken in” for it
to develop its optimal characteristics.

1. Minimum level mark
Rear brake
1. Minimum level mark
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
Observe these precautions:
● When checking the fluid level,
make sure that the top of the brake
fluid reservoir is level.
● Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking performance.
Recommended brake fluid:
DOT 4
● Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
● Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
● Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Always clean up spilled fluid
immediately.
● As the brake pads wear, it is nor-
mal for the brake fluid level to gradually go down. However, if the
brake fluid level goes down suddenly, have a Yamaha dealer
check the cause.

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 charts
represent quick and easy procedures
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.

MOTORCYCLE CARE AND STORAGE
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
7
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-
EAU41351
ucts onto seals, gaskets, sprockets, the drive chain and wheel
axles. Always rinse the dirt and degreaser off with water.
Cleaning
ECA10770
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
windshields, cowlings, panels
and other plastic parts. 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
7-1
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 swingarm bearings, fork and brakes),
electric components (couplers,
connectors, instruments,
switches and lights), breather
hoses and vents.
● For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning compounds for plastic may leave
scratches on the windshield.
Test the product on a small hidden part of the windshield to
make sure that it does not leave
any marks. If the windshield is
scratched, use a quality plastic
polishing compound after
washing.
Page 75
MOTORCYCLE CARE AND STORAGE
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.
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.
After cleaning
1. Dry the motorcycle with a chamois
or an absorbing cloth.
2. Immediately dry the drive chain
and lubricate it to prevent it from
rusting.
3. Use a chrome polish to shine
chrome, aluminum and stainlesssteel parts, including the exhaust
system. (Even the thermally induced discoloring of stainlesssteel exhaust systems can be removed through polishing.)
4. To prevent corrosion, it is recommended to apply a corrosion protection spray on all metal,
including chrome- and nickel-plated, surfaces.
5. Use spray oil as a universal cleaner to remove any remaining dirt.
6. Touch up minor paint damage
caused by stones, etc.
7. Wax all painted surfaces.
8. Let the motorcycle dry completely
before storing or covering it.
EWA11130
WARNING
● Make sure that there is no oil or
wax on the brakes or tires.

● If necessary, clean the brake
discs and brake linings with a
regular brake disc cleaner or acetone, and wash the tires with
warm water and a mild detergent. Before riding at higher
speeds, test the motorcycle’s
braking performance and cornering behavior.
ECA10800
CAUTION:
● Apply spray oil and wax spar-
ingly and make sure to wipe off

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)
7
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 “OFF” position: Turn the fuel cock lever to
“OFF”.
EAU41511

3. Drain the fuel tank and fuel lines,
and the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up.
4. 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
install the spark plug and the
spark plug cap.

5. Lubricate all control cables and the
pivoting points of all levers and
pedals.
6. Check and, if necessary, correct
the tire air pressure, and then lift
the motorcycle so that both of its
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.
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
