YRC : Yamaha Ride Control
Yamaha Ride Control is a system that
controls the engine output based on data
received from the sensors and IMU.
The f u nct io ns listed be low re pre sent
individual YRC items which can be turned on/
conditions.
For details on the settings, see “MENU” in
the Owner’s Manual.
* The meter MENU screen cannot be
displayed if “T.TRIP” is selected when the
battery or meter is reconnected.
IMU : Inertial Measurement Unit
PWR : Power Delivery Mode
TCS : Spin control system
SCS : Slide control system
LCS : Launch control system
QSS : Quick shift system
LIF : Lift control system
ERS : Electric racing suspension by ÖHLINS
(available only with 2KS)
EBM : Engine brake managment system
IMU : Inertial Measurement Unit
IMU is 6-axis inertial measurement unit.
It consists of three gyro sensors (angular
sensors) that measure a: machine pitch,
b: roll, and c: yaw, and three G-sensors
(accelerometer) that measure acceleration in
the forward-backward, up-down and right-left
directions. YRC controls the engine output
based on data received from those sensors.
PWR : Power Delivery Mode
The power mode selection system consists of
valve opening depending on the degree of
throttle opening, thus providing the rider with
and the riding environment.
TIP
If the installation position or angle of the
inertial measurement unit is changed,
YRC does not function properly because
measurements are not available.
TCS : Spin control system
The spin control system helps maintain
traction when accelerating. If sensors detect
that the rear wheel is
starting to slip (uncontrolled spinning), the
spin control system assists by regulating
engine power as needed until traction is
restored.
This system supports the SCS to contribute
to a smoother ride.
If TCS is set to “OFF”, SCS, LCS, QSS and
LIF are also set to OFF automatically.
