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. See page 7-15
for tire specifications and for informa-
tion on servicing and 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.
 Shift the transmission into gear
(for models with a manual trans-
mission).
 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
 two standard keys
 a transponder (in each key)
 an immobilizer unit (on the vehicle)
 an ECU (on the vehicle)
 a system indicator light (page 4-8) A
bout the keys
The code re-registering key is used to
register codes in each standard key.
Store the code re-registering key in a
safe place. Use a standard key for daily
operation.
When key replacement or re-register-
ing is necessary, bring the vehicle and
the code re-registering key along with
any remaining standard keys to a
Yamaha dealer to have them re-regis-
tered.
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 co de re-reg istering key
is lost, the existin g stan dar d keys can still
be used to start the vehicle.
However, re gisterin g a new stan-
d ar d key is impossi ble. If all keys
have been lost or damag ed , the en-
tire immo bilizer system must be re-
placed . Therefore, han dle the keys
carefully.  Do not su bmerse in water.
 Do not expose to hi gh tempera-
tures.
 Do not place near mag nets.
 Do not place near items that
transmit electrical sig nals.
 Do not han dle rou ghly.
 Do not grin d or alter.
 Do not disassem ble.
 Do not put two keys of any im-
mo bilizer system on the same
key rin g.

TIP The engine must be running to
start the lap timer.
 The headlight will flash when the
dimmer/pass switch is pressed.
 Whenever the lap timer is paused,
it can be resumed using the dim-
mer/pass switch.Brake control icon “BC”
This icon is replaced by the auxiliary
system warning and coolant tempera-
ture warning indicators when they are
activated.
For more information on the BC sys-
tem see “BC” on page 3-6.
Error mo de warnin g “Err”
When an internal error occurs (e.g.,
communication with a system control-
ler has been cut off), the error mode
warning will appear as follows.
“Err” and “ ” indicator light indicates
an ECU error.
“Err” only indicates an ABS ECU error.
TIPDepending on the nature of the error,
the display may not function properly
and the TCS settings may be impossi-
ble to change. Additionally, the ABS
may not function properly. Use extra
care when braking and have a Yamaha
dealer check the vehicle immediately.Auxiliary system warnin g“”
This icon appears if a problem is de-
tected in a non-engine-related system.
Coolant temperature warnin g“”
This icon appears if the coolant tem-
perature reaches 116 °C (241 °F) or
higher. Stop the vehicle and turn off the
engine. Allow the engine to cool.NOTICE
ECA10022
Do not continue to operate the en-
g ine if it is overheatin g.Oil pressure warnin g“”
This icon appears when the engine oil
pressure is low. When the vehicle is
first turned on, engine oil pressure has yet to build, so this icon will come on
and stay on until the engine has been
started.
TIPIf a malfunction is detected, the oil
pressure warning icon will flash repeat-
edly.NOTICE
ECA26410
Do not continue to operate the en-

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 hydraulic unit is monitored by
the ABS ECU, which will revert the sys-
tem to conventional braking if a mal-
function occurs.
WARNING
EWA20891
The brake control system is not a
su bstitute for the use of proper ri d-
in g an d brakin g techniques. The
b rake control system cannot pre-
vent all loss of traction due to over-
b rakin g from excessive spee d, or
lateral wheel slip when brakin g on
slippery surfaces.
TIPThe ABS performs a self-diagnostic
test when the vehicle is started and
reaches a speed of 5 km/h (3 mi/h).
During this test, a clicking noise may
be audible from the hydraulic control
unit, and a vibration may be felt at the
brake lever or pedal, but this is normal.NOTICE
ECA20100
Be careful not to d amage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.1. Front wheel sensor rotor

Your Yamaha engine was designed to
use unleaded gasoline with a research
octane number of 95 or higher. If en-
gine knocking or pinging occurs, use a
gasoline of a different brand or higher
octane rating.
TIP This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).
 Confirm the gasoline pump nozzle
has the same fuel identification
mark.Gasohol
There are two types of gasohol: gaso-
hol containing ethanol and that con-
taining methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
