The rider is always responsi-
ble for adapting his/her driving
style.
Do not reduce the system's ex-
tra safety margin with careless
riding or unnecessary risks.
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
operating conditions may lead
to automatic deactivation of
BMW Motorrad ASC:
Riding on the rear wheel (per-
forming Wheelies) for an ex-
tended period with the ASC
deactivated.
Spinning the rear wheel with
the front brake applied and the
motorcycle stationary (Burn
Out).
Warm-up on the center or aux-
iliary 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 throttle
grip should never be suddenly
twisted back completely unless
the clutch is disengaged at
the same time. The engine's
braking torque could cause the
rear wheel to lock, resulting in
