Integral ABS
Partially integral brakes
Your motorcycle is equipped
with partially integral brakes.
Both front and rear brakes
are applied when you pull the
handbrake lever. The foot-
brake lever acts only on the
rear brake.
While the brakes are slow-
ing the motorcycle, the BMW
Motorrad Integral ABS ad-
apts braking-force distribution
between front and rear brakes
to suit the load on the motor-
cycle.
The integral braking
function makes it
very difficult to spin the
rear wheel by opening
the throttle with the front
brake applied to keep the
motorcycle stationary (burn-
out). Attempted burn-outs
can result in damage to the
rear brake and the clutch.
Do not attempt burn-outs.
How does ABS work?
The amount of braking force
that can be transferred to
the road depends on factors
hat include the coefficient of
friction of the road surface.
Loose stones, ice and snow
or a wet road all have much
lower coefficients of friction
than a clean, dry asphalt sur-
face. The lower the coeffi-
cient of friction, the longer the
braking distance.
If the rider increases braking
pressure to the extent that
braking force exceeds the
maximum transferrable limit,
the wheels start to lock and
the motorcycle loses its dir-
ectional stability; a fall is im-
minent. Before this situation
can occur, ABS intervenes
and adapts braking pressure
to the maximum transferrable
braking force, so the wheels
continue to turn and direc-
tional stability is maintained
irrespective of the condition of
the road surface.
What are the effects of
surface irregularities?
Humps and surface irregu-
larities can cause the wheels
to lose contact temporarily
with the road surface; if this
happens the braking force
that can be transmitted to
the road can drop to zero.
