Do not reduce the additional
safety provided with risky
driving.
Special situations
As lean angles increase, accel-
eration potential is also progres-
sively restricted by the laws of
physics. This can result in de-
layed acceleration when exiting
very tight curves.
The system compares the rota-
tion speeds of the front and rear
wheels to detect any tendency
for the rear wheel to spin or lose
traction. If the system registers
implausible data for an extended
period of time it will deactivate
the ASC functionality as safety
precaution and a display will alert
you to an ASC error. A self-diag-
nosis routine must be completed
before the error will be displayed.
The following non-standard op-
erating conditions may lead to
automatic deactivation of ASC:
Riding on rear wheel (wheelie)
for a longer period
Rear wheel spinning in place
with front brake engaged (burn
out)
Heating up on the main or ad-
ditional stand at idle or with
gear engaged
Switching the ignition off and on
again and then riding the mo-
torcycle at more than a specific
minimum speed reactivates the
ASC.
Minimum speed for ASC
activation
min 6 mph (min 10 km/h)
If the front wheel loses contact
with the ground under extreme
acceleration, the ASC reduces
the engine torque, maintain-
ing the reduction until the front
wheel makes contact with the
ground again.
BMW Motorrad recommends
that you respond to this condi-
tion by twisting back the throttle
grip somewhat to return to stable
dynamic operating conditions as
quickly as possible.
On a slippery surface, the throt-
tle grip should never be suddenly
twisted back completely unless
the clutch is disengaged at the
same time. The engine's brak-
ing torque could cause the rear
wheel to lock, resulting in unsta-
ble vehicle conditions. ASC is
unable to intervene effectively
under these conditions.
