BMW R nineT 2019, Rider'S Manual, Page: 91 / 206

Exceptional riding
conditions:
Riding on the rear wheel
(wheelie) with deactivated ASC
for a prolonged period of time
Moving the rear wheel in a
circle while applying the front
wheel brake (burn-out)
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged
Switch the ignition off and on
and subsequently move the
vehicle at a speed over 5 km/h to
reactivate 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 roadway
On very loose surfaces (e.g. sand
or snow) ASC control interven-
tions may reduce the driving
power at the rear wheel to an
extent where the rear wheel no
longer rotates sufficiently. In this
case, BMW Motorrad recom-
mends to temporarily switch off
ASC.
Please note that the rear wheel
will spin on loose surfaces and
remember to release the throttle
grip in due time before reaching
firm surfaces.
Then reactivate ASC.
