ABS control
From a technical standpoint,
ABS Pro adjusts the ABS con-
trol to the angle of inclination of
the motorcycle in dependence
on the respective riding situation.
Signals for the roll and yaw rate
and the lateral acceleration are
used to determine the inclination
of the motorcycle.
With an increasing inclination, the
braking pressure gradient is in-
creasingly limited at the start of
braking. This results in a slower
pressure buildup. In addition, the
pressure modulation in the range
of the ABS control is more uni-
form.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and riding sta-
bility with the best possible de-
celeration, even in curves.
Automatic Stability
Control (ASC)
without riding modes Pro OE
How does ASC work?
BMW Motorrad ASC compares
the wheel speeds of the front
and rear wheels. From the speed
difference the slip, and with it
the stability reserves on the rear
wheel are determined. When a
slip limit is exceeded, the engine
torque is adapted by the engine
management system.
What are the design
characteristics of the
BMW Motorrad ASC?
BMW Motorrad ASC is designed
as an assistance system for the
rider and for riding on public
roads. The extent to which the
rider affects ASC control can be
considerable (weight shifts when
cornering, loose luggage on the
motorcycle), especially when ap-
proaching the limits imposed by
the laws of physics.
The Enduro riding mode should
be activated for off-road riding. In
this mode the controlling inter-
vention by the ASC is carried out
later, enabling controlled drifting.
The system is not optimized for
the special conditions encoun-
tered under extreme weather
during off-road and race-track
use. BMW Motorrad ASC can be
switched off under these condi-
tions.
WARNING
Risky riding style
Accident hazard despite ASC
The rider is always responsi-
ble for adapting his/her driving
style.
Do not reduce the system's ex-
tra safety margin with careless
riding or unnecessary risks.
