ports.
Do not run engine outdoors whe-
re engine exhaust can be drawn
into a building through openings
such as windows and doors.
Loading
Adding accessories or cargo to your
motorcycle can adversely affect sta-
bility and handling if the weight distri-
bution of the motorcycle is changed.
To avoid the possibility of an acci-
dent, use extreme caution when
adding cargo or accessories to your
motorcycle. Use extra care when
riding a motorcycle that has added
cargo or accessories. Here, along
with the information about accesso-
ries below, are some general guideli-
nes to follow if loading cargo to your
motorcycle:
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
Operation of an overloaded vehicle
could cause an accidentWhen loading within this weight limit,
keep the following in mind:
Cargo and 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 and cargo are
securely attached to the
motorcycle before riding. Check
accessory mounts and cargo res-
traints frequently.
• Properly adjust the suspension
for your load (suspension-
adjustable models only), and
check the condition and pres-
sure of your tires.• Never attach any large or
heavy items to the handlebar,
front fork, or front fender. The-
se items, including such cargo
as sleeping bags, duffel bags,
or tents, can create unstable
handling or a slow steering res-
ponse.
This vehicle is not designed to
pull a trailer or to be attached
to a sidecar.
Genuine Yamaha Accessories
Choosing accessories for your vehicle
is an important decision. Genuine
Yamaha accessories, which are avai-
lable 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 modifica-
tions for Yamaha vehicles. Yamaha is
not in a position to test the products
that these aftermarket companies
produce. Therefore, Yamaha can neit-
her endorse nor recommend the use
of accessories not sold by Yamaha or
modifications not specifically recom-

Coolant temperature warning light
“”
This warning light comes on if the
engine overheats. If this occurs, stop
the engine immediately and allow the
engine to cool.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains
on, have a Yamaha dealer check the
electrical circuit.
ECA10021
Do not continue to operate the
engine if it is overheating.
TIP
For radiator-fan-equipped vehi-
cles, the radiator fan(s) automati-
cally switch on or off according to
the coolant temperature in the
radiator.
If the engine overheats, see page
6-40 for further instructions.

ler check the self-diagnosis system.
(See page 3-8 for an explanation of
the self-diagnosis device.)
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then
go off.
If the warning light does not come on
initially when the key is turned to
“ON”, or if the warning light remains

models)
If this warning light comes on or flas-
hes while riding, the ABS may not
work correctly. If this occurs, have aYamaha dealer check the system as
soon as possible. (See page 3-12).
EWA10081
If the ABS warning light comes on
or flashes while riding, the brake
system reverts to conventional bra-
king. Therefore, be careful not to
cause the wheels to lock during
emergency braking. If the warning
light comes on or flashes while
riding, have a Yamaha dealer check
the brake system as soon as possi-
ble.
The electrical circuit of the warning
light can be checked by turning the
key to “ON”. The warning light should
come on for a few seconds, and then

When the key is turned to “ON”, the
tachometer needle sweeps once
across the r/min range and then
returns to zero r/min in order to test
the electrical circuit.

decreases to XT660Z 6.7 L (1.76 US
gal, 1.46 Imp.gal) - XT660ZA 5.8 L
(1.53 US gal, 1.28 Imp.gal), the bot-
tom segment of the fuel meter starts
flashing, and the tripmeter display
automatically changes to the fuel
reserve tripmeter mode “F-TRIP” and
starts counting the distance traveled
from that point. In that case, pushing
the “SELECT” button switches the
display between the various tripmeter
modes in the following order:
F-TRIP TRIP 1 TRIP 2 F-TRIP
To reset a tripmeter, select it by pus-
hing the “SELECT” button, and then
push the “RESET” button for at least

ABS (for ABS models)
The Yamaha ABS (Anti-lock Brake
System) features a dual electronic
control system, which acts on the
front and rear brakes independently.
The ABS is monitored by an ECU,
which will have recourse to manual
braking if a malfunction occurs.
EWA10090
The ABS performs best on long
braking distances.
On certain (rough or gravel)
roads, the braking distance
may be longer with than wit-
hout the ABS. Therefore,
always keep a sufficient distan-
ce to the vehicle ahead to
match the riding speed.
TIP
When the ABS is activated, the
brakes are operated in the usual
way. A pulsating action may be
felt at the brake lever or brake
pedal, but this does not indicate
a malfunction.

Read the Owner’s Manual carefully to
become familiar with all controls. If
there is a control or function you do
not understand, ask your Yamaha
dealer.

then try again. Each starting attempt
should be as short as possible to pre-
serve the battery. Do not crank the
engine more than 10 seconds on any
one attempt.

EWA10570
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, 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, inclu-ding the tires, should be left to
a Yamaha dealer, who has the
necessary professional know-
ledge and experience.
It is not recommended to patch
a punctured tube. If unavoida-
ble, however, patch the tube
very carefully and replace it as
soon as possible with a high-
quality product.
EAU21942
Spoke wheelsEWA10610
The wheels on this model are not
designed for use with tubeless
tires. Do not attempt to use tube-
less tires on this model.
To maximize the performance, durabi-
lity, and safe operation of your
motorcycle, note the following points
regarding the specified wheels.
The wheel rims should be chec-
ked for cracks, bends or warpa-
ge, and the spokes for looseness
or damage before each ride. If
any damage is found, have a
Yamaha dealer replace the whe-
el. Do not attempt even the sma-
llest repair to the wheel. A defor-
med 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.
