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

Shift pe dalThe shift pedal is located on the left
side of the motorcycle. To shift the
transmission to a higher gear, move
the shift pedal up. To shift to the trans-
mission to a lower gear, move the the
shift pedal down. (See page 6-3.)
The shift rod is equipped with a shift
sensor, which is part of the quick shift
system. The shift sensor reads up and
down movement, as well as the
strength of the input force when the
shift pedal is moved.
TIPTo prevent unintended shifts, QSS is
programmed to ignore unclear input
signals. Therefore, be sure to shift us-
ing quick and sufficiently forceful in-
puts.

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 4-18.)
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 b est with
lon g b rakin g d istances.
 On certain surfaces, such as
roug h 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

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 refueling , 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.
