YRC (Yamaha Ride Control)Yamaha Ride Control is a system that
incorporates numerous sensors and
controls to support an improved riding
experience. The vehicle senses and
can react to forces along the longitudi-
nal (front-to-back), lateral (left-to-right),
and vertical (up-and-down) axes. Lean
angle and G-force accelerations are
also detected. This information is pro-
cessed multiple times a second and the
related physical systems are automati-
cally adjusted as necessary. The fol-
lowing functions represent individual
YRC items which can be turned on/off
or adjusted to suit various riders and
riding conditions. For setting details,
see pages 4-10 and 4-14.
WARNING
EWA18221
The Yamaha Ride Control (YRC) sys-
tem is not a substitute for the use of
proper riding techniques or the ex-
pertise of the operator. This system
cannot prevent loss of control
caused by rider errors such as trav-
eling faster than warranted by road
and traffic condition s, including lossof traction due to excessive speed
when entering turns, when acceler-
ating hard at a sharp lean angle, or
while braking, and it cannot prevent
front wheel slip or front wheel lift. As
with any motorcycle, always ride
within in your limits, be aware of sur-
rounding conditions, and ride ap-
propriately for those conditions.
Become thoroughly familiar with the
way the motorcycle handles with
various YRC settings before at-
tempting more advanced maneu-
vers.
PWR
The power delivery mode system con-
sists of four different control maps
which regulate throttle valve opening in
relation to the degree of throttle grip op-
eration, thus providing you with a selec-
tion of modes to fit your preferences
and the riding environment.
TCS
The traction control system helps main-
tain traction when accelerating. If sen-
sors 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 traction con-
trol system indicator/warning light
flashes to let the rider know that traction
control has engaged.

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.

2. Use the mode switch up button or
down button to change the select-
ed item value (vertical scrolling is
not possible).
TIP
Under certain conditions, such as
when the vehicle is in motion, the
throttle grip is turned, excessive
wheel slip is detected, etc., certain
YRC items cannot be adjusted.

When a YRC item is highlighted
but cannot be adjusted, the YRCitem box will return to black. To turn off the traction control system
select TCS with the center button, then
push and hold the up button until TCS
OFF is displayed. To turn TCS back on,
select TCS OFF and then press the
down button (TCS will return to its pre-
vious setting).
TIPTurning off the traction control system
will turn off the SCS, LCS, and LIF sys-tems for all YRC modes.
YRC items LCS/QS/LIF
The on/off status of YRC items LCS,
QSS, and LIF is shown here. When any
of these systems are registered (not set
to OFF) for the currently selected YRC
mode, its respective icon will appear. When LCS is registered for the current-
ly selected YRC mode, its icon will be
grey. To activate the launch control
system, press and hold the center but-
ton until the LCS icon stops flashing
and turns white.
TIPLCS, QSS, and LIF system setting lev-
els can only be adjusted from theMENU screen.
Clock
The clock uses a 12-hour time system.
Lap timer
This stopwatch function measures and
records up to forty laps. On the main
screen, the lap timer shows the current
lap time and lap number (indicated by
the LAP mark). Use the Pass/LAP
switch to mark lap times. When a lap is
completed, the lap timer will show the
latest lap time (marked by the LATEST
indicator) for five seconds.

MODE-B, MODE-C, MODE-D by ad-
justing the setting levels (or on/off sta-
tus as applicable) of YRC items PWR,
TCS, SCS, LCS, QSS, and LIF.
TIP
TCS has 9 setting levels.

Whenever there are more selec-
tions (setting levels or modes)
available than can be shown on
the screen at one time, a scroll bar
will appear to notify you that addi-
tional selections are available byscrolling.
PWR
Select PWR-1 for the most aggressive
throttle response, PWR-2 and PWR-3
for smoother throttle grip/engine re-
sponse, and use PWR-4 for rainy days
or whenever less engine power is desir-
able. TCS
This model uses a variable traction
control system. For each setting level,
the further the vehicle is leaned over,
the greater the amount of traction con-
trol (system intervention) is applied.
There are 9 setting levels available.
Setting level 1 applies the least amount
of overall system intervention, while
setting level 9 applies the greatest
amount of overall traction control.
TIP
TCS can only be turned on or off
via the main screen using the
mode switch.

When TCS has been turned off,
TCS, SCS, LCS, and LIF will be
set to OFF and cannot be adjust-
ed. When TCS is turned on again,
these related-traction control func-
tions will return to their previoussetting levels.
SCS
SCS can be set to OFF, 1, 2, and 3.
OFF turns the slide control system off,
