BCThe brake control system regulates hy-
draulic brake pressure for the front and
rear wheels when the brakes are ap-
plied and wheel lock is detected. This
system has two settings.
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
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.

li g ht “ ”
When the main switch is turned off and
30 seconds have passed, the indicator
light will flash steadily to indicate the
immobilizer system is enabled. After 24
hours have passed, the indicator light
will stop flashing, however the immobi-
lizer system is still enabled.TIPWhen the vehicle is turned on, this light
should come on for a few seconds and
then go off. If the light does not come
on, or if the light remains on, have a
Yamaha dealer check the vehicle.
Transpon der interference
If the immobilizer system indicator light
flashes in the pattern, slowly 5 times
then quickly 2 times, this could be
caused by transponder interference. If
this occurs, try the following. 1. Make sure there are no other im- mobilizer keys close to the main
switch.
2. Use the code re-registering key to start the engine.
3. If the engine starts, turn it off, and try starting the engine with the
standard keys.
4. If one or both of the standard keys do not start the engine, take the
vehicle and all 3 keys to a Yamaha
dealer to have the standard keys
re-registered.

BC
The brake control system has two set-
tings, BC1 and BC2. Select BC1 when
only standard ABS is desired. Select
BC2 to have the brake control system
further regulate brake pressure while
cornering to suppress lateral wheel
slip.TIPFor skilled riders and when riding at the
track, due to varying conditions, the
BC2 brake system may engage sooner
than expected relative to your desired
cornering speed or intended cornering
line.
QSThe quick shift system indicators are
divided into QS and QS sections.
QS and QS are not linked and
can be independently turned on or off.
QS can be set to ON or OFF.
OFF turns the respective upshift or
downshift function off, and the clutch
lever must then be used when shifting
in that direction.TIPIf the QSS setting cannot be changed:
turn the engine off with the gear posi-
tion set to neutral, then change the set-
ting.
“Shift In
dicator”
This module allows a custom shift indi-
cator to be set. When the engine r/min
(rotations per minute) are in the speci-
fied range, the gear indicator will flash.
This module has 3 options:
“IND Mode” - the shift indicator can be
turned ON/OFF
“IND Start” - the r/min at which the in-
dicator starts flashing can be chosen.
Once selected, rotate the wheel switch
up/down to increase or decrease the
r/min value by increments of 200 r/min.
“IND Start” is settable between 6000 -
12800 r/min.
“IND Stop” - the r/min at which the in-
dicator stops flashing can be chosen.
Once selected, rotate the wheel switch
up/down to increase or decrease the
km/h

EAU91461
Brake control system (BC)The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels independently when the
brakes are applied and wheel lock is
detected. This system has two settings
which can be changed in the settings
MENU. (See page 4-15.)
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
BC2 uses additional data from the IMU
to regulate applied brake power when
cornering to suppress lateral wheel
slip.
Regarding ABS, operate the brakes as
you would conventional brakes. When
the brake control system engages, a
pulsating sensation may be felt at the
brake lever or brake pedal as the hy-
draulic unit rapidly applies and reduces
brake pressure. In this situation, conti-
nue to apply the brake lever and brake
pedal to allow the ABS to work—do
not “pump the brakes” as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient d istance
from the vehicle ahead 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
