not always be relied on to pre-
vent the rear wheel from lifting
off the ground.
What are the design
characteristics of the
BMW Motorrad ABS?
The BMW Motorrad ABS en-
sures driving stability on any
surface within the limits of driv-
ing physics. The system is not
optimized for the special condi-
tions encountered under extreme
weather during off-road and race-
track use.
Special situations
To detect the tendency of the
wheels to lock up, the speeds
of the front and rear wheel are
compared. If implausible values
are detected over a longer period
of time, the ABS function is de-
activated for safety reasons and
an ABS error is indicated. A self-
diagnosis routine must be com-
pleted before the error will be
displayed.
In addition to problems on the
BMW Motorrad ABS, unusual
driving conditions can also lead
to a fault message.
Unusual riding conditions:
With ASC switched off: rid-
ing for a lengthy period with
the back wheel lifted off the
ground (wheelie)
Rear wheel rotating with the
vehicle held stationary by ap-
plying the front brake (burn-
out).
Rear wheel skidding on a slip-
pery surface for a lengthy pe-
riod, for example deceleration
using the engine's braking ef-
fect
Should a fault code occur due to
one of the driving conditions de-
scribed above, the ABS function
can be reactivated by switching
the ignition off and then on again.
How important is regular
maintenance?
WARNING
Failure to have maintenance
performed on the brake sys-
tem regularly.
Accident hazard
To ensure that the
BMW Motorrad ABS is in a
properly maintained condition,
it is vital that the specified
service intervals are kept to.
Reserves for safety
But remember: the potentially
shorter braking distances which
BMW Motorrad ABS permits
must not be used as an excuse
for careless riding. ABS is pri-
marily a means of ensuring a
safety margin in genuine emer-
gencies.
Be careful in curves! When you
apply the brakes on a corner,
