134 TECHNOLOGY IN DETAIL
How important is regular
preventive maintenance?
WARNING
Brake system not regularly
serviced
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
The potentially shorter
braking distances that the
BMW Motorrad ABS permits
must not be used as an excuse
for careless riding. ABS is
primarily a means of ensuring
a safety margin in genuine
emergencies.
Be careful on curves! When
you apply the brakes on a
curve, the motorcycle's weight
and momentum take over and
even the BMW Motorrad ABS
is unable to counteract their
effects.
Further development of ABS
to ABS Pro
with riding modes Pro
In the past, the BMW Motorrad
ABS system provided for a very
high level of safety while brak-
ing during straight-ahead rid-
ing. Now ABS Pro also offers
increased safety even when
braking in curves. ABS Pro pre-
vents the wheels from locking
up, even in the event of quick
brake actuation. ABS Pro re-
duces abrupt changes in steer-
ing forces, especially during
shock braking, and therefore
decreases the risk of the mo-
torcycle lifting off the ground
inadvertently.
ABS control
From a technical standpoint,
ABS Pro adjusts the ABS con-
trol to the angle of inclination
of the vehicle in dependence
on the respective riding situ-
ation. Signals for the roll and
yaw rate and the lateral accel-
eration are used to determine
the inclination of the vehicle.
With an increasing angle, the
brake pressure gradient is in-
creasingly limited at the start
of braking. This results in a
slower pressure buildup. In ad-
dition, the pressure modulation
