BMW F800GT - Automatic Stability Control (ASC)

Reserves for safety
The potentially shorter braking
distances which BMW Motorrad
ABS permits must not be used
as an excuse for careless riding.
ABS is primarily a means of en-
suring a safety margin in genuine
emergencies.
WARNING
Braking when cornering
Risk of accident despite ABS
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 margin of
safety offered by this system.

How does ASC work?
The BMW Motorrad ASC com-
pares the speed of rotation of the
front wheel and the rear wheel.
The differential is used to com-
pute slip as a measure of the
reserves of stability available at
the rear wheel. If slip exceeds a
certain limit, the engine control
intervenes and adapts the engine
torque accordingly.
What is the design
baseline for
BMW Motorrad ASC?
The BMW Motorrad ASC is de-
signed as an assistant system
for the rider during use on public
roads. The extent to which the
rider affects ASC control can be
considerable (weight shifts when
cornering, items of luggage loose
on the motorcycle), especially
when style of riding takes rider
and machine close to the limits
imposed by physics.
The system is not optimised for
special requirements that apply
under extreme competitive situ-
ations off-road or on the race
course. The BMW Motorrad
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.

offered by this system.
