BMW F 800 GS Rider's Manual page 92

The ASC is reactivated by
7
switching the ignition on and
off and then driving at a speed
90
above 3 mph (5 km/h).
If the front wheel loses contact
with the ground during extreme
acceleration, the ASC reduces
the engine torque until the front
wheel touches the ground again.
In this case, BMW Motorrad rec-
ommends turning back the throt-
tle grip somewhat to achieve
a stable driving state again as
quickly as possible.
On a slippery surface, the
throttle grip should never be
z
suddenly turned back completely
without pulling the clutch at
the same time. The engine
braking torque can cause the
rear wheel to block, resulting in
an unstable driving state. This
case cannot be controlled by the
BMW Motorrad ASC.
