cally adjusts accordin
g to the vehicle’s
lean angle. To maximize acceleration,
when the vehicle is upright a less
amount of traction control is applied.
When cornering, a greater amount of
traction control is applied.
TIP
The traction control system may
engage when the vehicle travels
over a bump.
You may notice slight changes in
engine and exhaust sounds when
the traction control or other YRC
systems engage.
When TCS is turned off, SCS,
LCS, and LIF are also turned offautomatically.
WARNING
EWA15432
The traction control system is not a
substitute for riding appropriately
for the conditions. Traction control
cannot prevent loss of traction due
to excessive speed when entering
turns, when accelerating hard at a
sharp lean angle, or while braking,
and cannot prevent front wheel slip-
ping. As with any motorcycle, ap-
proach surfaces that may be
slippery with caution and avoid es-pecially slippery surfaces.
When the key is turned to “ON”, the
traction control system automatically
turns on. The traction control system
can be turned on or off manually only
when the key is in the “ON” position and
the motorcycle is stopped.TIPTurn the traction control system off to
help free the rear wheel if the motorcy-
cle gets stuck in mud, sand, or othersoft surfaces.
NOTICE
ECA16801
Use only the specified tires. (See
page 7-19.) Using different sized
tires will prevent the traction control
system from controlling tire rotationaccurately.
SCS
The slide control system regulates en-
gine power output when a sideward
slide is detected in the rear wheel. It ad-
justs power output based on data from
the IMU. This system supports the TCS
to contribute to a smoother ride.
LCS
The launch control system helps the rid-
er achieve smooth and swift launches
from the starting grid. It keeps engine
speed from rising above 8,000 r/min
even when the throttle grip is fully
turned. The LCS regulates engine pow-
er output in conjunction with the TCS
and LIF systems for optimal traction and
reduced wheel lift.

NOTICE
ECA22950
Even when using LCS, the clutch le-
ver must be released gradually toavoid clutch damage.TIPLCS is intended for track use only.
QSS
The quick shift system allows for clutch
lever-less, electronically-assisted shift-
ing. When the sensor on the shift rod
detects the appropriate motion in the
shift pedal, engine power output is mo-
mentarily adjusted to allow for the gear
change to occur.
QSS does not operate when the clutch
lever is pulled, therefore normal shifting
can be done even when QSS is set to
on. Check the QS indicator for current
status and usability information. Upshifting conditions
Vehicle speed of at least 20 km/h
(12 mi/h)
Engine speed of at least 2200 r/min
Accelerating (open throttle)
Downshifting conditions
Vehicle speed of at least 20 km/h
(12 mi/h)
Engine speed of at least 2000 r/min
Engine speed sufficiently away
from red zone
Decelerating and throttle ful-
ly-closed
TIP
QS and QS can be individu-
ally set.
Shifting into or out of neutral mustbe done using the clutch lever.
LIF
The lift control system reduces the rate
at which the front wheel will continue to
rise during extreme acceleration, such
as during starts or out-of-corner exits.
When front-wheel lift is detected, en-
gine power is regulated to slow front-wheel lift while still providing good
acceleration.

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 place near items that
transmit electrical signals.
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.

minimize the risk of losing the code
re-registering key (red bow), keep it in a
safe place and only use it for codere-registering.
