AUX BMW MOTORRAD K 1200 S 2007 Rider's Manual (in English)

exceptional riding conditions can
lead to a fault message being
issued.
Exceptional riding
conditions:Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged.
Rear wheel locked by the en-
gine brake for a lengthy period,
for example while descending
off-road.
If a fault message is issued on
account of exceptional riding
conditions as outlined above, you
can reactivate the ABS function
by switching the ignition off and
on again.
What significance
devolves on regular
maintenance?
Invariably, a technical sys-
tem cannot perform beyond
the abilities dictated by its level
of maintenance.
In order to ensure that the BMW
Motorrad ABS is always main-
tained in optimum condition, it
is essential for you to comply
strictly with the specified inspec-
tion intervals.
Reserves for safetyThe potentially shorter braking
distances which BMW Motorrad
Integral ABS permits must not be
used as an excuse for careless
riding. ABS is primarily a means
of ensuring a safety margin in
genuine emergencies.
Take care when cornering. When
you apply the brakes on a corner,
the motorcycle's weight and momentum take over and even
BMW Motorrad Integral ABS is
unable to counteract their effects.
Electronic engine
management with BMW
Motorrad ASC
OE
How does ASC work?The BMW Motorrad ASC com-
pares the speed of rotation of the
front wheel and the rear wheel.
The differential is used to com-
pute slip as a measure of the
reserves of stability available at
the rear wheel. If slip exceeds a
certain limit the electronic engine
management system intervenes,
adapting engine torque accord-
ingly.

What is the design
baseline for BMW
Motorrad ASC?BMW Motorrad ASC is designed
as an assistant system for the
rider and for use on public roads.
The extent to which the rider af-
fects ASC control can be consid-
erable (weight shifts when cor-
nering, items of luggage loose
on the motorcycle), especially
when style of riding takes rider
and machine close to the limits
imposed by physics. The system
is not optimised for special re-
quirements that apply under ex-
treme competitive situations off-
road or on the track. You have
the option of deactivating the
BMW Motorrad ASC system for
these circumstances.Even ASC is constrained by
the laws of physics. Invari-
ably, the rider bears responsibil-
ity for assessing road and traffic conditions and adopting his or
her style of riding accordingly.
Do not take risks that would neg-
ate the additional safety offered
by this system.
Special situationsIn accordance with the laws of
physics, the ability to accelerate
is restricted more and more as
the angle of heel increases. Con-
sequently, there can be a per-
ceptible lag in acceleration out of
very tight bends.
The speeds of the front and
rear wheels are compared as
one means of detecting the rear
wheel's incipient tendency to
spin or slip sideways. If the sys-
tem registers implausible values
for a lengthy period the ASC
function is deactivated for safety
reasons and an ASC fault mes-
sage is issued. Self-diagnos-
is has to complete before fault
messages can be issued.
The BMW Motorrad ASC can
shut down automatically under
the exceptional riding conditions
outlined below.
Exceptional riding
conditions:
Riding for a lengthy period with
the front wheel lifted off the
ground (wheelie) and ASC de-
activated.
Rear wheel rotating with the
motorcycle held stationary by
applying the front brake (burn-
out).
Heating up with the motorcycle
on the centre stand or an auxil-
iary stand, engine idling or with
a gear engaged.
Accelerating the motorcycle to
a speed in excess of 10 km/h
after switching the ignition off
and then on again reactivates the
ASC.

the on-board power supply sys-
tem is minimised, the supply to
the power socket is cut off ap-
proximately 15 minutes after the
ignition is switched off, and it is
also temporarily interrupted dur-
ing the start procedure.Cable routingThe cables from the power sock-
et to the auxiliary device must be
routed in such a way that they:Do not impede the rider
Do not restrict or obstruct the
steering angle and handling
characteristics
Cannot be trapped
Incorrectly routed cables
can impede the rider.
Route the cables as described
above.
LuggageCorrect loading
Overloading and imbal-
anced loads can adversely
affect the motorcycle's handling.
Do not exceed the permissible
gross weight and be sure to
comply with the instructions on
loading.
Set spring preload, damping
characteristic and tyre pres-
sures to suit total weight.
Adjust the spring preload for
rear wheel ( 58)
Check the tyre pressure
( 62)
Adjust the damping for rear
wheel ( 59)
Ensure that the case volumes
on the left and right are equal.
Make sure that the weight is
uniformly distributed between
right and left. Pack heavy items at the bot-
tom and toward the inboard
side.
Note the maximum permissible
payload of the cases and the
speed limit for riding with cases
on the motorcycle.
Payload of cases
with OA Case: ≤8kg
Maximum permissible
speed for riding with
cases fitted to the motorcycle
with OA Case:
≤180 km/h
Note the maximum permissible
payload of the tank rucksack
and the speed limit for riding
with a tank rucksack on the
motorcycle.

Front-wheel standUseA front-wheel stand for simple,
safe changing of the front wheel
is available from BMW Motorrad.
The BMW special tool number
is 36 3 971 and the front-wheel
stand is available from your au-
thorised BMW Motorrad dealer.
You also need the adapters with
the BMW special tool number
36 3 973.The BMW Motorrad front
wheel stand is not designed
to support motorcycles not fitted
with a centre stand or without
other auxiliary stands. A motor-
cycle resting only on the front
wheel stand and the rear wheel
can topple.
Place the motorcycle on its
centre stand or another auxiliary
stand before lifting the front
wheel with the BMW Motorrad
front-wheel stand.
