Dynamic Esa - BMW R 1250 GS Adventure Rider's Manual

166 ENGINEERING DETAILS
Rear-wheel hop when rider
downshifts.
Sharp braking during sporty
riding.
In the same way as DTC trac-
tion control, dynamic engine
brake control compares the
wheel circumferential velocities
of the front and rear wheels.
Additional information on the
bank angle enables dynamic
engine brake control to calcu-
late slip and the reserve of sta-
bility at the rear wheel.
If slip overshoots the applic-
able limit, the throttle valves are
opened very slightly to increase
engine torque. Slip is reduced
and the vehicle is stabilised.
Effect of dynamic engine
brake control
In ECO, RAIN and ROAD rid-
ing modes: Maximum stabil-
ity.
In DYNAMIC and
DYNAMIC PRO riding
modes: High stability.
In ENDURO riding mode: Min-
imum stability.
in ENDURO PRO riding mode,
dynamic engine brake control
is inactive.

The electronic chassis
and suspension setting
Dynamic ESA is able to adjust
your motorcycle automatically
to the load. If the spring
preload is set to
rider does not have to change
the load settings.
When driving off and when rid-
ing, the system monitors the
suspension on the rear wheel
and corrects the spring preload
in order to set the riding posi-
tion correctly. The damping is
also adjusted automatically to
the load.
Via ride height sensors,
Dynamic ESA detects the
movements in the chassis
and suspension and responds
by adjusting the EDC valves.
The chassis and suspension
will thus be adapted to the
characteristics of the terrain.
Dynamic ESA calibrates itself at
regular intervals to ensure the
system functions correctly.
