“D-MODE”“D-MODE” is an electronically con-
trolled engine performance system.
WARNING
EWA18440
Do not change the d rive mo de while
the vehicle is movin g.The “D-MODE” system consists of 4
different control maps which regulate
engine response and output, thus pro-
viding you with a selection of modes to
fit your preferences and the riding envi-
ronment.
D-MODE 1 - Sporty engine response
D-MODE 2 - Moderate engine re-
sponse
D-MODE 3 - Mild engine response
D-MODE 4 - Mild engine response and
limits engine outputTIP The current “D-MODE” setting is
shown in the MODE display. (See
page 4-11.)
 The current “D-MODE” setting is
saved when the vehicle is turned
off. 
The “D-MODE” is controlled by
the MODE switches, see page 4-4
for more information.

“TCS-MODE”This model is equipped with adjustable
traction, slide, and lift control systems
(TCS, SCS and LIF). These are
grouped together into “TCS-MODE”.
“TCS-MODE” has 4 settings:
“TCS-MODE M” is customizable in the
settings MENU, see page 4-15.
TCS
The traction control system helps
maintain traction when accelerating. If
sensors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The stability
control indicator light “ ” flashes to
let the rider know that traction control
has engaged.

QSSThe 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.

This module allows you to set the
clock.
When the clock module is selected, the
hours will be highlighted.
Set the hours by rotating the wheel
switch. Push the switch to confirm and
highlight the minutes.
After confirming the minutes, you will
be returned to the top MENU screen.
“All Reset”
This module resets all settings items
(except the odometer and clock) to
their default or factory presets.
Select YES to reset all items. After se-
lecting YES, all items will be reset and
the screen will automatically return to
the top MENU screen.

Clutch leverTo disengage the drivetrain from the
engine, such as when shifting gears,
pull the clutch lever toward to the han-
dlebar. Release the lever to engage the
clutch and transmit power to the rear
wheel.TIPThe lever should be pulled rapidly and
released slowly for smooth shifting.
(See page 6-3.)

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.

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
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

Vehicle data recor din gThis model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research, statisti-
cal analysis and development purpos-
es.
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

special Yamaha diagnostic tool is at-
tached to the vehicle, such as when
maintenance checks or service proce-
dures are performed.
