ABS intervention
Technically speaking, depending
on the riding situation ABS Pro
adapts ABS intervention to the
motorcycle's bank angle. Signals
for rate of roll and rate of yaw
and lateral acceleration are used
to calculate bank angle.
As the motorcycle is heeled over
more and more as it banks into
a corner, an increasingly strict
limit is imposed on the brake-
pressure gradient for the start of
brake application. This slows the
build-up of brake pressure to a
corresponding degree. Addition-
ally, pressure modulation is more
uniform across the range of ABS
intervention.
Advantages for the rider
The advantages of ABS Pro for
the rider are sensitive response
and high braking and directional
stability combined with best-case
deceleration of the motorcycle,
even when cornering.
Automatic Stability
Control (ASC)
How does the ASC work?
The ASC system compares the
speed of rotation of the front
wheel and the rear wheel. The
differential is used to compute
slip as a measure of the reserves
of stability available at the rear
wheel. If slip exceeds a certain
limit, the engine control inter-
venes and adapts the engine
torque accordingly.
What is the design
baseline for the ASC?
ASC is designed as an assist-
ance system for the rider and
for use on public roads. The ex-
tent to which the rider affects
ASC control can be consider-
able (weight shifts when corner-
ing, items of luggage loose on
the motorcycle), especially when
style of riding takes rider and ma-
chine close to the limits imposed
by physics.
The system is not optimised
for special requirements that
apply under extreme competit-
ive situations on the track. The
ASC can be deactivated in these
cases.
WARNING
Risky riding
Risk of accident despite ASC
Invariably, the rider bears re-
sponsibility for assessing road
and traffic conditions and ad-
opting his or her style of riding
accordingly.
Do not take risks that would
negate the additional safety
offered by this system.
