
Do not run engine indoors. Even if
you try to ventilate engine exhaust
with fans or open windows and
doors, carbon monoxide can rap-
idly 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 where
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 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.
Here, along with the information about
accessories below, are some general
guidelines 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 accident.
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. Se-
curely pack your heaviest items as
close to the center of the vehicle as
possible and make sure to distrib-
ute the weight as evenly as possi-
ble on both sides of the motorcycle
to minimize imbalance or instabili-
ty.

Shifting weights can create a sud-
den imbalance. Make sure that ac-
cessories and cargo are securely
attached to the motorcycle before
riding. Check accessory mounts
and cargo restraints frequently.
Properly adjust the suspension
for your load (suspension-ad- justable 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. These
items, including such cargo as
sleeping bags, duffel bags, or
tents, can create unstable han-
dling or a slow steering re-
sponse.

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 avail-
able 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 acces-
sories or offer other modifications for
Yamaha vehicles. Yamaha is not in a
position to test the products that these
aftermarket companies produce.
Therefore, Yamaha can neither en-


Check that the fuel cock (if
equipped) is in the off position and
that there are no fuel leaks.

Shift the transmission into gear (for
models with a manual transmis-
sion).

Secure the motorcycle with
tie-downs or suitable straps that
are attached to solid parts of the
motorcycle, such as the frame or
upper front fork triple clamp (and
not, for example, to rubber-mount-
ed handlebars or turn signals, or
parts that could break). Choose
the location for the straps carefully
so the straps will not rub against
painted surfaces during transport.

The suspension should be com-
pressed somewhat by the
tie-downs, if possible, so that the
motorcycle will not bounce exces-
sively during transport.

Immobilizer systemThis vehicle is equipped with an immo-
bilizer 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

two standard keys

a transponder (in each key)

an immobilizer unit (on the vehicle)

an ECU (on the vehicle)

a system indicator light (page 4-7)
About the keys
The key with the red bow is used to reg-
ister codes in each standard key. Store the code re-registering key in a safe
place. When necessary, take the vehi-
cle 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.
TIP
Keep the standard keys as well as
keys of other immobilizer systems
away from the code re-registering
key.

Keep other immobilizer system
keys away from the main switch as
they may cause signal interfer-ence.
NOTICE
ECA11823
DO NOT LOSE THE CODE RE-REG-
ISTERING KEY! CONTACT YOUR
DEALER IMMEDIATELY IF IT IS
LOST! If the code re-registering key
is lost, the existing standard keys
can still be used to start the vehicle.
However, registering a new stan-
dard key is impossible. If all keyshave been lost or damaged, the en-
tire immobilizer system must be re-
placed. Therefore, handle the keys
carefully.

Do not submerse in water.

Do not expose to high tempera-
tures.

Do not place near magnets.

Do not handle roughly.

Do not grind or alter.

Do not disassemble.

Do not put two keys of any im-
mobilizer system on the samekey ring.

NOTICE
ECA10022
Do not continue to operate the en-gine if it is overheating.
Oil pressure warning “ ”
This icon appears when the engine oil
pressure is low. When the main switch
is first turned to ON, engine oil pressure
has yet to build, so this icon will come
on and stay on until the engine has
been started. NOTICE
ECA26410
Do not continue to operate the en-gine if the oil pressure is low.
Error mode warning “Err”
When an internal error occurs (e.g.,
communication with a system controller
has been cut off), the error mode warn-
ing will appear as follows.
“Err” and “ ” indicates an ECU error.
“Err” only indicates an HCU (hydraulic
control unit) error.TIPDepending on the nature of the error, the display may not function properly
and YRC settings may be impossible to
change. Additionally, ABS and UBS
may not function properly. Use extra
care when braking and have a Yamaha
dealer check the vehicle immediately.

TIPSee Brake system for more informa-
tion on how the UBS and ABS systemswork.
The brake lever is equipped with a
brake lever position adjusting dial. To
adjust the distance between the brake
lever and the throttle grip, turn the ad-
justing dial while holding the lever
pushed away from the throttle grip.
Make sure that the appropriate setting
on the adjusting dial is aligned with the
“ ” mark on the brake lever.

Brake pedalThe brake pedal is located on the right
side of the motorcycle. To apply the
rear brake, press down on the brake
pedal.
EAU67041
Brake systemThis model is equipped with an inte-
grated anti-lock brake system (ABS)
and a variable unified brake system
(UBS).
Regarding ABS, operate the brakes as
you would conventional brakes. If the
ABS is activated, a pulsating sensation
may be felt at the brake lever or brake
pedal. In this situation, continue to ap-
ply the brakes and let the ABS work; do
not “pump” the brakes as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.

On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer withthe ABS than without.
The ABS and UBS hydraulic control
unit is monitored by the ABS ECU,
which will revert the system to conven-

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, followthese instructions. 1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters and
clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank. 3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately wipe
off spilled fuel with a clean, dry,
soft cloth, since fuel may deteri-
orate painted surfaces or plastic
parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swallow
some gasoline or inhale a lot of gas-
oline vapor, or get some gasoline in your eyes, see your doctor immedi-
ately. If gasoline spills on your skin,
wash with soap and water. If gaso-
line spills on your clothing, change
your clothes.
EAU75320
NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
