it with coolant as soon as possible,
otherwise the cooling system will not
be protected against frost and corro-
sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.
[ECB01012]
6. Install the panel when finished servicing
the vehicle. To change the coolant
The coolant must be changed at the intervals
specified in the periodic maintenance chart.
Have a Yamaha dealer change the coolant.
WARNING! Never attempt to remove the
radiator cap when the engine is hot.

EBU35141Cleaning the spark arrester
WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe cover by removingthe tailpipe cover bolts. 2. Remove the tailpipe bolts.
3. Remove the tailpipe by pulling it out of
the muffler, and then remove the gasket.
4. Tap the tailpipe lightly, and then use a wire brush to remove any carbon depos-
its from the spark arrester portion of the
tailpipe and inside of the tailpipe housing.1. Tailpipe cover

WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See pages 9-57, 9-59 for wheel
removal and installation procedures.)
EBU32490Checking the parking brake padsEach brake pad is provided with a wear indi-
cator groove, which allows you to check the
brake pad wear without having to disassem-
ble the brake. If a brake pad has worn to the
point that the wear indicator groove has al-
most disappeared, have a Yamaha dealer re-
place the brake pads as a set.1. Lining thickness

WARNING
EWB04160Improper maintenance can result in loss of
braking ability or YCC-S clutch operation.
Observe these precautions:
Insufficient brake or YCC-S clutch fluid
may allow air to enter the brake or
YCC-S clutch system, reducing braking
or YCC-S clutch performance.
 Clean the filler caps before removing.
Use only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion. 
Be careful that water or dust does not
enter the brake or YCC-S clutch fluid
reservoir when refilling. Water will signif-
icantly lower the boiling point of the fluid
and may result in vapor lock.
NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately. As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads or brake system leakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low YCC-S
clutch fluid level may indicate YCC-S clutch
system leakage; therefore, be sure to check
the YCC-S clutch system for leakage. If the
brake or YCC-S clutch fluid level goes down

EBU36620Brake light switchThe brake light, which is activated by the
brake pedal, should come on just before
braking takes effect. Since the brake light
switch is a component of the YCC-S system,
it must be adjusted by a Yamaha dealer, who
has the necessary professional knowledge
and experience.EBU35930Cable inspection and lubrication
WARNING
EWB03380Damaged cables could restrict operation,
which may cause an accident or injury. In-
spect control cables frequently and re-
place damaged cables. Corrosion can
result when the outer covering of control
cables becomes damaged. Cables can
also become frayed or kinked.
Lubricate the cable ends. If the cables do not
operate smoothly, ask a Yamaha dealer to re-
place them.EBU36760Pedal lubricationThe pivoting parts of the brake and accelera-
tor pedals should be lubricated periodically to
prevent rust and ensure smooth operation.Recommended lubricant:Yamalube LubezAll (synthetic lubricant spray with PTFE)

were designed to match the performance ca-
pabilities and to provide the best combination
of handling, braking, and comfort. It is best to
replace all four tires at the same time. If that is
not possible, you must replace the tires in
pairs (front or rear) with tires of the same size
and type as the originals. Never replace just
one tire.
WARNING
EWB03390Installing improper tires on your Yamaha
YXZ1000R can affect handling and stabili-
ty. This can cause a loss of control. The tires listed below have been approved by
Yamaha Motor Manufacturing Corporation of America for this model.
EBU33090Wheel installation1. Install the wheel and the nuts.
2. Lower the vehicle so that the wheel is on the ground.
3. Tighten the wheel nuts in a crisscross pattern to the specified torque.
WARNING
EWB03400Do not reverse the rims on your Yamaha
YXZ1000R to widen the track width. In-
stalling wheels improperly increases the
risk of wheel failure and accidents. Front tire:Size:29 x 9.00R-14NHS

EBU35232BatteryThis model is equipped with a 12–volt VRLA
(valve–regulated lead–acid) battery. There is
no need to check the electrolyte or to add dis-
tilled water. However, the battery lead con-
nections need to be checked and tightened,
and the battery terminals cleaned if corroded.
If the battery seems to have discharged, re-
charge it as soon as possible.
WARNING
EWB03410Avoid battery contact with skin, eyes, or
clothing. Shield eyes when working near
batteries. Keep out of reach of children.
You could be poisoned or severely burnedby the sulfuric acid in battery electrolyte. In
case of accidental contact with battery
electrolyte:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Get prompt
medical attention.
EYES: Flush with water for 15 minutes and
get prompt medical attention.

WARNING
EWB03420Batteries may produce explosive gases.
Ventilate when charging or using in a
closed space. Keep batteries away from
sparks, flames, cigarettes, or other sourc-
es of ignition. To remove the battery
1. Turn the key to “ ” (off).
2. Remove panel A. (See page 9-11.)
