BMW Motorrad F 900 XR, Rider'S Manual

Page: 137 / 261

Like the DTC traction control,
the dynamic engine brake con-
trol compares the wheel circum-
ferential velocities of the front
and rear wheel. With the aid of
more information on the angle,
the dynamic engine brake control
can determine the slip or the sta-
bility reserve at the rear wheel.
If the slip exceeds the respec-
tive limit value, the engine torque
is increased by slightly opening
the throttle valves. The slip is
reduced, and the vehicle is stabi-
lized.
Effect of the dynamic engine
brake control
In the RAIN and ROAD riding
modes: maximum stability.
In the DYNAMIC and
DYNAMIC PRO riding modes:
high stability.
Dynamic ESA
with Dynamic ESA OE
Dynamic ESA function
Using ride height sensors,
Dynamic ESA detects the
movements of the suspension
and responds to them by
adjusting the EDC valves. As a
result, the suspension is adjusted
to the conditions of the surface.
Dynamic ESA calibrates itself at
regular intervals to ensure that
the system is operating correctly.

Selection
In order to adjust the motorcy-
cle to the road condition and the
desired riding experience, it is
possible to select one of the fol-
lowing riding modes:
RAIN
ROAD (standard mode)
with riding modes Pro
OE
DYNAMIC
With coding plug installed:
DYNAMIC PRO
For each of these riding modes,
there is a coordinated setting for
the ABS and ASC⁄DTC systems,
the dynamic engine brake control
and the throttle response.
