Reserves for safety
But remember: the potentially
shorter braking distances which
BMW Motorrad Integral ABS per-
mits must not be used as an ex-
cuse for careless riding. ABS is
primarily a means of ensuring a
safety margin in genuine emer-
gencies.
Be careful in curves! When you
apply the brakes on a corner,
the motorcycle's weight and
momentum take over and even
BMW Motorrad Integral ABS is
unable to counteract their effects.
Further development of
ABS to ABS Pro
In the past, the BMW Motorrad
ABS system provided for a very
high level of safety while brak-
ing during straight-ahead rid-
ing. Now ABS Pro also offers
increased safety even when brak-
ing in curves. ABS Pro prevents
locking-up of the wheels even
in case of rapid brake actuation.
ABS Pro reduces abrupt changes
in steering forces, especially dur-
ing panic braking, and therefore
decreases the risk of unwanted
wheelies occurring.
ABS control
From a technical standpoint,
ABS Pro adjusts the ABS con-
trol to the angle of inclination of
the motorcycle in dependence
on the respective riding situa-
tion. Signals for the roll and yaw
rate and the lateral acceleration
are used to determine the incli-
nation of the motorcycle. The
signals come from the yaw rate
sensor, which is already used for
Dynamic Traction Control DTC
and for Dynamic ESA.
With an increasing inclination, the
braking pressure gradient is in-
creasingly limited at the start of
braking. This results in a slower
pressure buildup. In addition, the
pressure modulation in the range
of the ABS control is more uni-
form.
Advantages for the driver
The advantages of ABS Pro for
the rider are sensitive response
and high braking and riding sta-
bility with the best possible de-
celeration, even in curves.
Engine management
with BMW Motorrad
DTC
How does DTC work?
The BMW Motorrad DTC com-
pares the wheel speeds of the
front and rear wheel. Differences
in the relative rotation speeds
allow the system to determine
the slip rate, and thus the sta-
bility reserves at the rear wheel.
The engine-management system
adapts the engine torque when
the slip limit is exceeded.
