Antilock Brake System

(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 footbrake lever acts
only on the rear brake.

ATTENTION
Attempted burn-out despite
Integral braking function
Damage to rear brake and clutch
Burn-out must only occur from
a vehicle standstill. Burn-out
is not proper vehicle use and
may therefore lead to fault
messages.
How does ABS work?
The amount of braking force that
can be transferred to the road
depends on factors that 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 surface.
The lower the coefficient of fric-
tion, the longer the braking dis-
tance.
If the rider increases braking
pressure to the extent that brak-
ing force exceeds the maximum
transferable limit, the wheels start
to lock and the motorcycle loses
its directional stability; a fall is
imminent. Before this situation
can occur, ABS intervenes and
adapts braking pressure to the
maximum transferable braking
force, so the wheels continue
to turn and directional stability
is maintained irrespective of the
condition of the road surface.
What are the effects of
surface irregularities?
Humps and surface irregularit-
ies can cause the wheels to lose
contact temporarily with the road
surface; if this happens the brak-
ing force that can be transmit-
ted to the road can drop to zero.
If the rider brakes in this situ-
ation, the ABS has to reduce the
brake pressure in order to ensure
driving stability when resuming
contact with the road. Up to this
point, BMW Motorrad Integral
ABS assumes an extremely low
coefficient of friction (gravel, ice,
snow) so that the road wheels
turn in every conceivable situ-
ation and so ensure driving sta-
bility. As soon as is registers the
actual circumstances, the system
reacts instantly and adjusts brak-
