Antilock Braking
System (ABS)
Partially integral brake
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.
The BMW Motorrad Integral ABS
adapts the braking force distribu-
tion between the front and rear
wheel brake to the loading of the
motorcycle during braking with
ABS control.

spite integral function
Damage to rear-wheel brake and
clutch
Do not perform burn-out.
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
lower 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 transferable brak-
ing force is exceeded when the
rider increases the brake pres-
sure, the wheels begin to lock
and driving stability is lost, and
a fall can result. Before this sit-
uation occurs, ABS is activated
and the brake pressure is ad-
justed to the maximum transfer-
able braking force. This enables
the wheels to continue to turn
and maintains driving stability re-
gardless of the road surface con-
dition.
What happens when
rough roads are
encountered?
Bumpy or rough roads can briefly
lead to a loss of contact between
the tires and the road surface,
until the transferable braking
force is reduced to zero. If the
brakes are applied in this sit-
uation, the ABS must reduce
the brake pressure to ensure
driving stability when contact
to the road is restored. At this
point, the BMW Motorrad Integral
ABS must assume extremely low
friction coefficients (gravel, ice,
snow) so that the road wheels
