SPECIAL FEATURES
EAU66291
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 longitudal
(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” on page 4-14.
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.

“Unit”
This module allows you to set the fuel
consumption units, and for certain mar-
kets, the display can be switched be-
tween kilometers and miles.
When using kilometers, the fuel con-
sumption units can be changed be-
tween km/L or L/100km. When using
miles, MPG will be available.
To set the distance or fuel consumptionunits1. From the MENU screen, select “Unit”. 2. “km or mile” and “km/L or L/
100km” are displayed.
TIPFor markets with kilometer-based mod-
els, only “km/L or L/100km” is dis-played.

Brake pedalThe brake pedal is located on the right
side of the motorcycle. To apply the
rear brake, press down on the brake
pedal.
EAU67041
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 amount of rear wheel braking force to
be applied by the UBS is based on ve-
hicle attitude and lean angle. However,
operating only the brake pedal will not
generate any brake pressure at the
front brake.
For full braking performance, apply
both the brake lever and brake pedal si-
multaneously.
When both the brake lever and the
brake pedal are applied simultaneous-
ly, the UBS will control the distribution
of braking force between the two
wheels.
TIP
The UBS does not function until
the vehicle starts moving.

After coming to a stop while apply-
ing the brake lever, the UBS is still
enabled. As further squeezing of
the brake lever will not increase
the braking power of the rear
brake, apply the rear brake should
further braking power be neces-
sary (such as when parking on a
slope).
The UBS disables after the brake
lever is released.
When the vehicle starts moving,
the UBS is re-enabled.
