1operator and may limit control
ability, therefore, such accesso-
ries 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
dangerous loss of lights or engine
power.
Aftermarket Tires an d Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. Refer to page
6-16 for tire specifications and more in-
formation on replacing your tires.
Transportin g the Motorcycle
Be sure to observe following instruc-
tions before transporting the motorcy-
cle in another vehicle.  Remove all loose items from the
motorcycle. 
Check that the fuel cock (if
equipped) is in the “OFF” position
and that there are no fuel leaks.
 Point the front wheel straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Shift the transmission in 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 mo-
torcycle, such as the frame or up-
per front fork triple clamp (and not,
for example, to rubber-mounted
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 mo-
torcycle will not bounce exces-
sively during transport.

Immo bilizer 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 (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 3-5.)
The key with the red bow is used to
register codes in each standard key.
Since re-registering is a difficult pro-
cess, take the vehicle along with all
three keys to a Yamaha dealer to have
them re-registered. Do not use the key
with the red bow for driving. It should
only be used for re-registering the
standard keys. Always use a standard
key for driving.
NOTICE
ECA11822
 DO NOT LOSE THE CODE RE-
REGISTERING KEY! CONTACT
YOUR DEALER IMMEDIATELY
IF IT IS LOST! If the co de re-re g-
isterin g key is lost, reg istering
new co des in the stan dar d keys
is impossib le. The stan dar d
keys can still be used to start
the vehicle, however if cod e re-
re gisterin g is require d (i.e., if a
new stan dar d key is mad e or all
keys are lost) the entire immo bi-
lizer system must be replaced .
Therefore, it is hi ghly recom- men
ded to use either stan dar d
key an d keep the co de re-reg is-
tering key in a safe place.
 Do not su bmerse any key in wa-
ter.
 Do not expose any key to exces-
sively hi gh temperatures.
 Do not place any key close to
ma gnets (this inclu des, but not
limite d to, pro ducts such as
speakers, etc.).
 Do n

ot place items that transmit
electrical si gnals close to any
key.
 Do not place heavy items on any
key.
 Do not grin d any key or alter its
shape.
 Do not d isassemble the plastic
part of any key.
 Do not put two keys of any im-
mo bilizer system on the same
key rin g.
 Keep the stan dar d keys as well
as keys of other immo bilizer
systems away from this vehi-
cle’s co de re-reg istering key.

Brake ped alThe brake pedal is located on the right
side of the motorcycle. To apply the
rear brake, press down on the brake
pedal.
EAU63040
ABSThe Yamaha ABS (Anti-lock Brake
System) features a dual electronic con-
trol system, which acts on the front and
rear brakes independently.
Operate the brakes with ABS as you
would conventional brakes. If the ABS
is activated, a pulsating sensation may
be felt at the brake lever or brake ped-
al. In this situation, continue to apply
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 d istance
from the vehicle ahea d to match the
ri din g speed even with ABS.
 The ABS performs best with
lon g b rakin g d istances.
 On certain surfaces, such as
rou gh or g ravel roa ds, the b rak-
in g d istance may be lon ger with
the ABS than without.The ABS is monitored by an ECU,
which will revert the system to conven-
tional braking if a malfunction occurs.
TIP The ABS performs a self-diagno-
sis test each time the vehicle first
starts off after the key is turned to
“ON” and the vehicle has traveled
at a speed of 10 km/h (6 mi/h) or
higher. During this test, a “click-
ing” noise can be heard from the
hydraulic control unit, and if the
brake lever or brake pedal is even
slightly applied, a vibration can be
felt at the lever and pedal, but
these do not indicate a malfunc-
tion.
 This ABS has a test mode which
allows the owner to experience
the pulsation at the brake lever or
brake pedal when the ABS is op-
erating. However, special tools are
required, so please consult your
Yamaha dealer.NOTICE
ECA20100
Be careful not to d amage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline an d gasoline vapors are
extremely flammab le. To avoid fires
an d explosions an d to re duce the
risk of injury when refuelin g, follow
these 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 spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painte d surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous an d can cau-
se injury or death. Han dle gasoline
with care. Never siphon gasoline by
mouth. If you shoul d swallow some
g asoline or inhale a lot of gasoline
vapor, or get some g asoline in your
eyes, see your d octor immediately. If g
asoline spills on your skin, wash
with soap an d water. If g asoline
spills on your clothin g, chan ge your
clothes.
EAU57692
NOTICE
ECA11401
Use only unlea ded g asoline. The use
of lead ed g asoline will cause severe

Vehicle data recor din gThis model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research and de-
velopment purposes. This data will be
uploaded only when a special Yamaha
diagnostic tool is attached to the vehi-
cle, such as when maintenance checks
or service procedures are performed.
Although the sensors and recorded
data will vary by model, the main data
points are:
 Vehicle status and engine perfor-
mance data
 Fuel-injection and emission-relat-
ed data
Yamaha will not disclose this data to a third party except:  With the consent of the vehicle
owner
 Where obligated by law
 For use by Yamaha in litigation
 For general Yamaha-conducted
research purposes when the data
is not related to an individual vehi-
cle nor owner
