ably increased amount of cur-

rent, which places a heavy
load on the battery.

During normal driving the bat-
tery is constantly charged, and
therefore has a sufficient
capacity.
During driving breaks of
several weeks, a trickle-
charger available from an
authorized BMW Motorrad
retailer should be connected
or the battery should be dis-
connected and recharged
before the next time the
motorcycle is driven.
During driving-safety training
courses an unusually high
number of ABS-controlled
braking actions take place
within a short time. Between
those actions there are waiting
and evaluation phases during
which the motorcycle is not
driven. The battery is heavily
loaded by the ABS control
actions, however at the same
time it is not recharged, as vir-
tually no driving takes place.
In isolated cases, braking
actions of this kind in this
artificially produced situation
during which the brake lever is
pulled with maximum force
and extremely quickly, in com-
bination with a decreasing
electrical system voltage,
push the ABS to technical
limits at which the control
function is no longer fulfilled.
Field observations by BMW
Motorrad show that no com-
parable situations occur in
road traffic or during circuit
training.
During safety training the fol-
lowing instructions must be
followed:
• Observe the warning and
control lights before each
braking exercise
• Drive a longer distance after
a maximum of five braking
exercises to charge the
battery
• Switch off consumers like
seat and hand grip heaters,
radio, navigation system and
accessories connected to
the sockets
• Switch off the ignition during
breaks and conversations. If
the engine is switched off
with the emergency ON/OFF
switch, the light and all elec-
tronic systems remain
switched on and load the
battery
