118 TECHNOLOGY IN DETAIL
WARNING
Braking in curves
Risk of accident despite ABS
The rider is always responsible for
adapting his/her driving style.
Do not reduce the additional safety
function with careless riding or
unnecessary risks.
AUTOMATIC STABILITY CONTROL (ASC)
How does ASC work?
BMW Motorrad ASC compares the wheel
centrifugal velocities of the front and rear
wheels. The speed difference is used to de-
termine the slip rate, and thus the stability
reserves at the rear wheel. The engine con-
trol adapts the engine torque when the slip
limit is exceeded.
WARNING
Risky riding style
Accident hazard despite ASC
The rider is always responsible for
adapting his/her driving style.
Do not reduce the system's extra safety
margin with careless riding or unneces-
sary risks.
Special situations
As the lean angle increases, the capacity to
accelerate is also increasingly limited by the
laws of physics. This can result in delayed
acceleration when exiting very tight turns.
Even in special riding situations, e.g. high
speeds, an unfavorable loading configuration
or overload, BMW Motorrad ASC is capable
of influencing the engine torque.
The system compares the rotational speeds
of the front and rear wheels to detect
whether the rear wheel is spinning without
traction or skidding. If implausible values are
detected over an extended period of time,
the ASC function is switched off for safety
reasons and an ASC error is displayed. A
self-diagnosis must be completed before the
fault message can be displayed.
In the following unusual driving conditions,
the BMW Motorrad ASC can be turned off
automatically.
Unusual riding conditions:
Riding on the rear wheel (wheelie) for an
extended period with ASC deactivated
Rear wheel spinning when stationary with
front wheel brake engaged (burn-out)
Warming up the engine on an auxiliary
stand in Neutral or with a gear engaged
ASC is reactivated by turning the ignition
off and on and then riding at a speed above
min 3 mph (min 5 km/h).
If the front wheel loses contact with the
ground under extreme acceleration, the ASC
reduces the engine torque until the front
wheel makes contact with the ground again.
If this happens, BMW Motorrad recommends
that you respond by twisting back the throt-
tle grip somewhat to return to stable riding
conditions as quickly as possible.
Slippery road
On very loose surfaces (e.g. sand and snow),
the interventions of the ASC can reduce the
drive force at the rear wheel to such a de-
gree that the rear wheel no longer turns suf-
ficiently. In this case, BMW Motorrad recom-
mends switching off the ASC temporarily.
Note that the rear wheel will spin on the
loose surface, and close the throttle grip in
a timely manner before reaching a solid sur-
face.
Then switch on ASC again.
RIDING MODE
Selection
In order to adjust the motorcycle to the road
condition and the desired riding experience,
it is possible to select one of the following
riding modes:
