the ignition is switched on, do
not touch electrically live
components, terminals or
wiring.
–Risk of fatal accident!
Work on the electrical system
only when the circuit has
been interrupted (switch off
ignition). For greater safety,
disconnect and insulate the
negative battery lead. If you intend to perform the
maintenance and general care
work described in the following
section yourself, you must pos-

Battery safety instructions
Gel batteries are maintenance-
free. Compliance with the
instructions below is important
in order to maximise battery life:
e Attention:
– Keep the surface of the battery clean and dry
– Do not attempt to open the battery
– Do not attempt to top up the battery with water
– Use only electronically
controlled battery chargers
with a limit voltage of 14.4 V to
charge the battery.
Correct upkeep, recharging
and storage will prolong the life
of the battery and are essential
if warranty claims are to be con-
sidered.
d Warning:
Do not attempt to jump-start
the motorcycle using the on-
board socket
–Risk of fire!
 Push-start the motorcycle only when the engine is
cold.
The load capacity of the
electrical wiring to the power
socket is not sufficient to start
the motorcycle from an outside
source.
e Attention:
Do not attempt to jump-start
the motorcycle if the battery is
completely flat: recharge the
battery instead.
Risk of damaging the control
units.

Battery maintenance instructions
Motorcycle out of use for a
lengthy period
 The battery has to be charged prior to lay-up periods of
more than one month.
e Attention:
If the battery is not
disconnected, the on-board
electronics (clock, etc.) will
discharge the battery. This can
cause the battery to run flat. If
this happens, warranty claims
will not be accepted.
Disconnect the ground (earth)
lead from the battery prior to a
lay-up. – Batteries that are not in use
must be stored in a cool
place. Do not store a
discharged battery
– If the battery is in storage for an extended period of time,
recharge it at regular intervals
of approx. 4 months. If the
battery is not disconnected
from the motorcycle's
systems, recharge it every 2
months at the latest
– Always fully recharge the bat-
tery before restoring it to use
In case of doubt ask a specialist,
preferably an authorised BMW
motorcycle dealer, to prepare
the vehicle for laying up and to
carry out the necessary battery
maintenance and storage
