Further development of ABS
to ABS Pro
In the past, the BMW Motorrad
ABS system provided for
a very high level of safety
while braking during straight-
ahead riding. Now ABS Pro
also offers increased safety
even when braking in curves.
ABS Pro prevents the wheels
from locking up, even in the
event that the brakes are
applied quickly. ABS Pro
reduces abrupt changes in
steering forces, especially
during shock braking, and
therefore decreases the risk of
the motorcycle 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 motorcycle in depen-
dence on the respective riding
situation. Signals for the roll
and yaw rate and the lateral
acceleration are used to de-
termine the inclination of the
motorcycle.
With an increasing inclination,
the brake pressure gradient
is increasingly limited at the
start of braking. This results in
a slower pressure buildup. In
addition, the pressure modu-
lation in the range of the ABS
control is more uniform.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and riding
stability with the best possible
deceleration, even in curves.
DYNAMIC TRACTION CON-
TROL (DTC)
How does traction control
work?
The traction control compares
the wheel centrifugal velocities
of the front and rear wheels.
The slip, and with it the stabil-
ity reserves at the rear wheel,
are determined from the speed
difference. The engine control
adapts the engine torque when
the slip limit is exceeded.
BMW Motorrad DTC is de-
signed as an assistance sys-
tem for the rider and for riding
on public roads. The extent to
which the rider affects DTC
control can be considerable
(weight shifts when cornering,
loose luggage on the motorcy-
cle), especially when approach-
ing the limits imposed by the
laws of physics.
