ABS

Partially integral brake
z
Your motorcycle is equipped with
a partially integral brake configu-
ration. Both front and rear brakes
are applied simultaneously when
you pull the handbrake lever.
The footbrake lever acts only on
the rear brake.
Spinning of the rear wheel
with the front brake pulled
(burn out) is made consider-
ably more difficult by the inte-
gral function. The result may be
damage to the rear wheel brake
and the clutch.
Burn-outs may be carried out
with the ABS function switched
off only.
How does ABS work?
The maximum braking force that
can be transferred to the road
surface is partially dependent on
the friction coefficient of the road
surface. Gravel, ice, snow and
wet roads offer a considerably
poorer friction coefficient than a
dry, clean asphalt surface. The
poorer the friction coefficient of
the road surface is, the longer
the braking distance will be.
If the maximum transferrable
braking force is exceeded when
the driver increases the brake
pressure, the wheels begin to
block and driving stability is lost,
and a fall can result. Before this
situation occurs, ABS intervenes
and adjusts the brake pressure
to the maximum transferrable
braking force. This enables the
wheels to continue to turn and
maintains driving stability regard-
less of the road surface condi-
tion.
What happens when
rough roads are
encountered?
Bumpy or rough roads can briefly
lead to a loss of contact be-
tween the tires and the road sur-
face, until the transferable brak-
ing force is reduced to zero. If
braking is carried out in this sit-
uation, ABS must reduce the
brake pressure to ensure driv-
ing stability when restoring con-
tact to the road. At this point in
time, the BMW Motorrad Integral
