WARNING
Braking in curves
Risk of accident despite ABS
The rider is always respon-
sible for adapting his/her
driving style.
Do not reduce the additional
safety function with careless
riding or unnecessary risks.
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 angle, the
brake pressure gradient is in-
creasingly limited at the start
of braking. This results in a
slower pressure buildup. In ad-
dition, the pressure modulation
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 circumferential ve-
locities of the front and rear
wheels. The slip, and with it
the stability reserves at the rear
wheel, are determined from
