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 func-
tions listed below represent individual
YRC items which can be turned on/off
or adjusted to suit various riders and
riding conditions. For setting details see
“MENU screen” on page 4-15.
WARNING
EWA18220
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 slipping or lift (“wheel-
ies”). As with any motorcycle, al-
ways ride within in your limits, be
aware of surrounding conditions,
and ride appropriately for those con-
ditions. 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.

“Wallpaper”
This module allows you to individually
set the STREET MODE and TRACK
MODE display background colors to
black or white for both day and night
settings. A photo sensor equipped in the instrument panel detects lighting
conditions and will automatically
change the display between its day and
night settings. The photo sensor also
controls a subtle automatic brightness
adjustment function within both day
and night modes to suit ambient light
conditions.

Brake systemThis model is equipped with an inte-
grated anti-lock brake system (ABS)
and a variable unified brake system
(UBS).
Regarding ABS, operate the brakes as
you would conventional brakes. If the
ABS is activated, a pulsating sensation
may be felt at the brake lever or brake
pedal. In this situation, continue to ap-
ply the brakes and let the ABS work; do
not “pump” the brakes as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.

On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer withthe ABS than without.
The ABS and UBS hydraulic control
unit is monitored by the ABS ECU,
which will revert the system to conven- tional braking if a malfunction occurs.
TIP
The ABS performs a self-diagno-
sis test when the vehicle is started
and reaches a speed of 10 km/h (6
mi/h). During this test, a “clicking”
noise may be audible from the hy-
draulic control unit, and a vibration
may be felt at the bake lever or
pedal, but this is normal.

This ABS has a test mode which
allows the owner to experience the
pulsation at the brake lever or
brake pedal when the ABS is oper-
ating. However, special tools are
required, so please consult yourYamaha dealer.
NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of theABS will result.
Regarding variable UBS, operating the
brake lever will generate corresponding
brake pressure at the front brake and to
a variable degree, the rear brake. The

Vehicle data recordingThis model’s ECU stores certain vehi-
cle data to assist in the diagnosis of
malfunctions and for research and de-
velopment purposes. This data will be
uploaded only when a special Yamaha
diagnostic tool is attached to the vehi-
cle, such as when maintenance checks
or service procedures are performed.
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
Yamaha will not disclose this data to a
third party except:

With the consent of the vehicle
owner

Where obligated by law

For use by Yamaha in litigation

For general Yamaha-conducted
research purposes when the data
is not related to an individual vehi-
cle nor owner
