BMW R 1200 RT Rider's Manual page 172

If the motorcycle is not to be
E
ridden for several weeks, a
trickle charger, which can be
2
obtained from your BMW
Motorrad dealer, should be
connected or the battery
disconnected and then
recharged before starting
riding again.
During rider safety training,
an unusual number of ABS-
controlled braking operations
take place in rapid succession
interspersed with periods of
waiting and assessment in
which the motorcycle is not
being ridden. The battery is
put under heavy load by the
ABS control actions, but at
the same time it is not being
recharged as practically no
riding is being done.
In isolated cases, in this
artificially created situation,
braking operations in which
the brake lever is operated
with maximum force and
extreme speed, in combina-
tion with declining on-board
supply voltage, can bring the
ABS up to its technical limits in
which its control function is no
longer fulfilled.
Field observations carried out
by BMW Motorrad indicate
that a comparable situation
has not arisen in traffic or even
during training rides.
The following notes must
be observed during safety
training:
• check the warning and
indicator lamps before any
braking exercise
• ride the motorcycle over
sufficient distance to charge
the battery after a maximum
of five braking exercises
• switch off consumers such
as seat and grip heating,
radio, navigation system and
accessories connected to
the power sockets
• in pauses and discussions,
switch off the ignition; if the
engine is switched off with
the emergency off switch,
the lights and all electronic
systems remain switched on
and drain the battery
How can I achieve the
shortest braking distance?
Dynamic load distribution
between the front and rear
wheels changes under
braking. The heavier the
brakes are applied, the more
load is transferred to the front
brake. The greater the load on
the wheel, the more braking
force can be transferred.
