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.

SAFETY INFORMATION
• Certain accessories can dis-
place 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 acces-
sories are not recommended.
●Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle's electrical sys-
tem, an electric failure could re-
sult, which could cause a danger-
ous loss of lights or engine power.
Gasoline and exhaust gas
●GASOLINE IS HIGHLY FLAM-
MABLE:
• Always turn the engine off
when refueling.
• Take care not to spill any gaso-
line on the engine or exhaust
system 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 poi-
sonous and may cause loss of
consciousness and death within a
short time. Always operate your
motorcycle in an area that has ad-
equate ventilation.
●Always turn the engine off before
leaving the motorcycle unattend-
ed and remove the key from the
main switch. When parking the
motorcycle, note the following:
• The engine and exhaust sys-
tem 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, other-
wise 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. If the motorcycle
should lean over, gasoline may
leak out of the 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 immediate-
ly. If any gasoline spills on your
skin or clothing, immediately
wash the affected area with soap
and water and change your
clothes.

Immobilizer system
1. Code re-registering key (red bow)
2. Standard keys (black bow)
This vehicle is equipped with an im-
mobilizer system to help prevent theft
by re-registering codes in the standard
keys. This system consists of the fol-
lowing.
●a code re-registering key (with a
red bow)
●two standard keys (with a black
bow) that can be re-registered
with new codes
●a transponder (which is installed
in the code re-registering key)
●an immobilizer unit
●an ECU
●an immobilizer system indicator
light (See page 3-3.)
The key with the red bow is used to reg-
ister codes in each standard key. Since
re-registering is a difficult process, take
the vehicle along with all three keys to a
Yamaha dealer to have them re-regis-
tered. Do not use the key with the red
bow for driving. It should only be used
for re-registering the standard keys. Al-
ways use a standard key for driving.
ECA11820CAUTION:
●DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the code re-reg-
istering key is lost, registering
new codes in the standard keys
is impossible. The standard keys
can still be used to start the ve-
hicle, however if code re-regis-
tering is required (i.e., if a new
standard key is made or all keys
are lost) the entire immobilizer
system must be replaced.
Therefore, it is highly recom-
mended to use either standardkey and keep the code re-regis-
tering key in a safe place.
●Do not submerse any key in
water.
●Do not expose any key to ex-
cessively high temperatures.
●Do not place any key close to
magnets (this includes, but not
limited to, products such as
speakers, etc.).
●Do not place heavy items on
any key.
●Do not grind any key or alter its
shape.
●Do not disassemble the plastic
part of any key.
●Do not put two keys of any im-
mobilizer system on the same
key ring.
●Keep the standard keys as well
as keys of other immobilizer
systems away from this vehi-
cle's code re-registering key.
●Keep other immobilizer system
keys away from the main
switch as they may cause sig-
nal interference.
