BMW Motorrad R nineT/5, Rider'S Manual

Page: 81 / 183

Exceptional riding
conditions:
Riding for a lengthy period with
the front wheel lifted off the
ground (wheelie) with ASC de-
activated
Rear wheel rotating with the
vehicle held stationary by ap-
plication of the front brake
(burn-out)
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged
Accelerating the motorcycle to
a speed in excess of 5 km/h
after switching the ignition off
and then on again reactivates the
ASC.
If the front wheel lifts clear of the
ground under severe accelera-
tion, the ASC reduces engine
torque until the front wheel re-
gains contact with the ground.
Under these circumstances,
BMW Motorrad recommends
rolling the throttle slightly closed
so as to restore stability with the
least possible delay.
When riding on a slippery sur-
face, never snap the throttle
twistgrip fully closed without
pulling the clutch at the same
time. Engine braking torque can
cause the rear wheel to lock, with
a corresponding loss of stability.
The BMW Motorrad ASC is un-
able to control a situation of this
nature.
Slippery surface
On very loose surfaces (for ex-
ample sand or snow), the AS-
C's attempts to control propuls-
ive power might reduce drive to
the extent that the rear wheel no
longer turns. Under these cir-
cumstances, BMW Motorrad re-
commends temporarily switching
off ASC.
Bear in mind that the rear wheel
will spin on the loose surface and
close the throttle in good time
before you reach a firm surface.
Then reactivate ASC.
