• Always obey the speed limit
and never travel faster than
warranted by road and traffic
conditions.
• Always signal before turning or
changing lanes. Make sure that
other motorists can see you.
The posture of the operator and
passenger is important for proper
control.
• The operator should keep both
hands on the handlebar and
both feet on the operator foo-
trests during operation to
maintain control of the
motorcycle.
• The passenger should always
hold onto the operator, the seat
strap or grab bar, if equipped,
with both hands and keep both
feet on the passenger foo-
trests. Never carry a passenger
unless he or she can firmly pla-
ce both feet on the passenger
footrests.
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 hel-
met is the single most critical factor in
the prevention or reduction of head
injuries.
Always wear an approved hel-
met.
Wear a face shield or goggles.
Wind in your unprotected eyes
could contribute to an impair-
ment of vision that could delay
seeing a hazard.
The use of a jacket, heavy boots,
trousers, gloves, etc., is effective
in preventing or reducing abra-
sions 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 sys-
tem become very hot during or
after operation and can cause
burns.
A passenger should also observe
the above precautions.
Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon
monoxide, a deadly gas. Breathing
carbon monoxide can cause heada-
ches, 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 over-
come and unable to save yourself.
Also, deadly levels of carbon monoxi-
de can linger for hours or days in
enclosed or poorly ventilated areas. If
you experience any symptoms of car-
bon monoxide poisoning, leave the
area immediately, get fresh air, and
SEEK MEDICAL TREATMENT.
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 car-
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-
Maximum load:
XT660Z: 190 kg (419 lb)
XT660ZA: 188 kg (414 lb)

mended by Yamaha, even if sold and
installed by a Yamaha dealer.
Aftermarket Parts, Accessories,
and Modifications
While you may find aftermarket pro-
ducts similar in design and quality to
genuine Yamaha accessories, recog-
nize that some aftermarket accesso-
ries or modifications are not suitable
because of potential safety hazards to
you or others. Installing aftermarket
products or having other modifica-
tions 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 “Loa-
ding” when mounting accessories.
Never install accessories or carry
cargo that would impair the per-
formance of your motorcycle.
Carefully inspect the accessory
before using it to make sure that
it does not in any way reduceground clearance or cornering
clearance, limit suspension tra-
vel, steering travel or control ope-
ration, or obscure lights or reflec-
tors.
• Accessories fitted to the hand-
lebar or the front fork area can
create instability due to impro-
per 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 aerody-
namic effects. Wind may
attempt to lift the motorcycle,
or the motorcycle may become
unstable in cross winds. These
accessories may also cause
instability when passing or
being passed by large vehicles.
• Certain accessories can dis-
place the operator from his or
her normal riding position. This
improper position limits the fre-edom of movement of the ope-
rator and may limit control abi-
lity, therefore, such accesso-
ries are not recommended.
• Use caution when adding elec-
trical accessories. If electrical
accessories exceed the capa-
city of the motorcycle’s electri-
cal system, an electric failure
could result, which could cau-
se 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
tires, rims, sizes, and combinations
may not be appropriate. Refer to
page 6-17 for tire specifications and
more information on replacing your
tires.
Transporting the Motorcycle
Be sure to observe following instruc-
tions before transporting the
motorcycle in another vehicle.
