Brake System - BMW K 1200 LT Owner's Manual

Brake system - with BMW Integral ABS
What must be observed
during driving safety
training?
Compared to normal braking, bra-
king during which the ABS must
intervene in a regulating manner
requires a considerably increased
amount of current, which places a
heavy load on the battery.
During normal driving the battery
is constantly charged, and there-
fore has a sufficient capacity.
During driving breaks of several
weeks, a trickle-charger available
from an authorized BMW Motor-
rad retailer should be connected
or the battery should be discon-
nected 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. Bet-
ween those actions there are wai-
ting and evaluation phases during
which the motorcycle is not dri-
ven.
The battery is heavily loaded by
the ABS control actions, however
at the same time it is not rechar-
ged, as virtually 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 combination
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
comparable situations occur in
road traffic or during circuit
training.
