SAFETY INFORMATION
• 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
footrests during operation to
maintain control of the motor-
cycle.
• 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
footrests.
• Never carry a passenger un-
less he or she can firmly place
both feet on the passenger
footrests.
●Never ride under the influence of
alcohol or other drugs.
●This motorcycle is designed for
on-road use only. It is not suitable
for off-road use.
Protective apparel
The majority of fatalities from motorcy-
cle accidents are the result of head in-
juries. The use of a safety helmet is
the single most critical factor in the
prevention or reduction of head in-
juries.
●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 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 ac-
cident.
●Never touch the engine or ex-
haust system during or after oper-
ation. They become very hot and
can cause burns. Always wear
protective clothing that covers
your legs, ankles, and feet.
●A passenger should also observe
the above precautions.
Modifications
Modifications made to this motorcycle
not approved by Yamaha, or the re-
moval of original equipment, may ren-
der the motorcycle unsafe for use and
may cause severe personal injury.
Modifications may also make your mo-
torcycle illegal to use.
Loading and accessories
Adding accessories or cargo to your
motorcycle can adversely affect stabili-
ty and handling if the weight distribution
of the motorcycle is changed. To avoid
the possibility of an accident, use ex-
treme caution when adding cargo or
accessories to your motorcycle. Use
extra care when riding a motorcycle
that has added cargo or accessories.

SAFETY INFORMATION
Here are some general guidelines to
follow if loading cargo or adding ac-
cessories to your motorcycle:
Loading
The total weight of the operator, pas-
senger, accessories and cargo must
not exceed the maximum load limit.
●Never attach any large or heavy
items to the handlebar, front fork,
or front fender. These items, in-
cluding such cargo as sleeping
bags, duffel bags, or tents, can
create unstable handling or a
slow steering response.
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 re-
sponsible for the proper selection, in-
stallation and use of non-Yamaha ac-
cessories. Use extreme caution when
selecting and installing any acces-
sories.
Keep the following guidelines in mind,
as well as those provided under "Load-
ing" when mounting accessories.
●Never install accessories or carry
cargo that would impair the perfor-
mance of your motorcycle. Care-
fully 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, or ob-
scure lights or reflectors.
• Accessories fitted to the han-
dlebar or the front fork area can
create instability due to improp-
er weight distribution or aerody-
namic 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 at-
tempt to lift the motorcycle, or
the motorcycle may become
unstable in cross winds. These
accessories may also cause in-
stability when passing or being
passed by large vehicles.

Maximum load:
186 kg (410 lb)
When 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.
Make sure to distribute the weight
as evenly as possible on both
sides of the motorcycle to mini-
mize imbalance or instability.
●Shifting weights can create a sud-
den imbalance. Make sure that
accessories and cargo are se-
curely attached to the motorcycle
before riding. Check accessory
mounts and cargo restraints fre-
quently.

Tires
To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified tires.
Tire air pressure
The tire air pressure should be
checked and, if necessary, adjusted
before each ride.
EWA10500
WARNING0
●The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the tempera-
ture of the tires equals the am-
bient temperature).
●The tire air pressure must be
adjusted in accordance with
the riding speed and with the
total weight of rider, passenger,
cargo, and accessories ap-
proved for this model.
EWA11020
WARNING0
Because loading has an enormous
impact on the handling, braking,
performance and safety character-
istics of your motorcycle, you
should keep the following precau-
tions in mind.
●NEVER OVERLOAD THE MO-
TORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider,
passenger, cargo, and acces-
sories does not exceed the
specified maximum load for the
vehicle.
●Do not carry along loosely
packed items, which can shift
during a ride.
●Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
