BMW R 1200 ST Rider's Manual page 88

When riding on a slippery
5
surface, never snap the
throttle twistgrip fully closed
86
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 BWM Motorrad
ASC is unable to control a
z
situation of this nature.
