Operating the kill switch
when riding can cause
the rear wheel to lock and thus
cause a fall.Do not operate the kill switch
when riding.
The emergency off switch is a
kill switch for switching off the
engine quickly and easily.
-Switch in normal position:

You cannot start the engine
unless the kill switch is in
the run position.
432zOperation

Use the ignition key to turn
seat lock1counter-clockwise
and hold it in this position.
Lift seat2at the rear and re-
lease the key.
Remove the seat.Place the seat, upholstered
side down, on a clean surface.
Installing seat
If too much pressure is ap-
plied in the forward direc-
tion, there is a danger that the
motorcycle will be pushed off its
stand.
Always make sure that the
motorcycle is stable and firmly
supported.
Push seat2forward into
mount3.
Firmly press down on the seat
at the rear.The seat engages with an aud-
ible click.
Check that the seat is secure.

pads more frequently and replace
the brake pads in good time.Air pressure and damping
characteristics
The off-road settings for air
pressure in the Air Damping
System and the front and rear
shock-absorber damping char-
acteristics will impair the motor-
cycle's handling characteristics
on surfaced roads.
If you have been off-roading, re-
member to correct the air pres-
sure in the Air Damping System
and the shock-absorber damping
characteristics before you return
to surfaced roads.
Deactivatable ABS
OE
You can deactivate the BMW
Motorrad Integral ABS for off-
roading ( 33).
BrakesHow can stopping
distance be minimised?Each time the brakes are applied,
a load distribution shift takes
place with the load shifting for-
ward from the rear to the front
wheel. The sharper the motor-
cycle decelerates, the more load
is shifted to the front wheel. The
higher the wheel load, the more
braking force can be transmitted
without the wheel locking.
To optimise stopping distance,
apply the front brakes rapidly and
keep on increasing the force you
apply to the brake lever. This
makes the best possible use
of the dynamic increase in load
at the front wheel. Remember
to pull the clutch at the same
time. In the "panic braking situ-
ations" that are trained so fre-
quently braking force is applied
as rapidly as possible and withthe rider's full force applied to
the brake levers; under these cir-
cumstances the dynamic shift
in load distribution cannot keep
pace with the increase in de-
celeration and the tyres cannot
transmit the full braking force to
the surface of the road. ABS has
to intervene to keep the front
wheel from locking; this increases
stopping distance.
Descending mountain
passes
There is a danger of the
brakes fading if you use
only the rear brakes when des-
cending mountain passes. Under
extreme conditions, the brakes
could overheat and suffer severe
damage.
Use both front and rear brakes,
and make use of the engine's
braking effect as well.

motorcycle with the side stand
extended.
Slowly lean the motorcycle to
the side until its weight is taken
by the stand and dismount to
the left.
If the motorcycle is on the
side stand, the surface of
the ground will determine wheth-
er it is better to turn the handle-
bars to the left or right. However,
the motorcycle is more stable on
a level surface with the handle-
bars turned to the left than with
the handlebars turned to the
right.
On level ground, always turn the
handlebars to the left to set the
steering lock.
Turn the handlebars to full left
or right lock.
Check that the motorcycle is
standing firmly.On a gradient, the motor-
cycle should always face
uphill; select 1st gear.
Lock the steering lock.
Removing motorcycle
from side standUnlock the steering lock.
From the left, grip the handle-
bars with both hands.
Pull the handbrake lever.
Swing your right leg over the
seat and lift the motorcycle to
the upright position.
Hold the motorcycle upright
and balanced.
An extended side stand can
catch on the ground when
the motorcycle is moving and
lead to a fall.
Retract the side stand before
moving the motorcycle.
Sit on the motorcycle and use
your left foot to retract the side
stand.
Refuelling
Fuel is highly flammable. A
naked flame close to the
fuel tank can cause a fire or ex-
plosion.
Do not smoke. Never bring a
naked flame near the fuel tank.
Fuel expands when hot.
Fuel escaping from an
overfilled tank could make its way
onto the rear tyre. This could
cause a fall.
Do not fill the tank past the bot-
tom edge of the filler neck.
Fuel attacks plastics, which
become dull or unsightly.
Wipe off plastic parts immediately
if they come into contact with
fuel.
Leaded fuel will destroy the
catalytic converter.
Use only unleaded fuel.

Brake system with
BMW Motorrad ABS
OE
How does ABS work?The amount of braking force that
can be transferred to the road
depends on factors hat include
the coefficient of friction of the
road surface. Loose stones, ice
and snow or a wet road all have
much lower coefficients of fric-
tion than a clean, dry asphalt sur-
face. The lower the coefficient
of friction, the longer the braking
distance.
If the rider increases braking
pressure to the extent that brak-
ing force exceeds the maxim-
um transferrable limit, the wheels
start to lock and the motorcycle
loses its directional stability; a fall
is imminent. Before this situation
can occur, ABS intervenes and
adapts braking pressure to the
maximum transferrable braking
force, so the wheels continueto turn and directional stability
is maintained irrespective of the
condition of the road surface.
What are the effects of
surface irregularities?Humps and surface irregularit-
ies can cause the wheels to lose
contact temporarily with the road
surface; if this happens the brak-
ing force that can be transmit-
ted to the road can drop to zero.
If the brakes are applied under
these circumstances the ABS
has to reduce braking force to
ensure that directional stability
is maintained when the wheels
regain contact with the road sur-
face. At this instant the BMW
Motorrad ABS must assume an
extremely low coefficient of fric-
tion, so that the wheels will con-
tinue to rotate under all imagin-
able circumstances, because this
is the precondition for ensuring
directional stability. As soon asis registers the actual circum-
stances, the system reacts in-
stantly and adjusts braking force
accordingly to achieve optimum
braking.
Rear wheel liftEven under severe braking, a
high level of tyre grip can mean
that the front wheel does not
lock up until very late, if at all.
Consequently, ABS does not in-
tervene until very late, if at all.
Under these circumstances the
rear wheel can lift off the ground,
and the outcome can be a high-
siding situation in which the mo-
torcycle can flip over.
Severe braking can cause
the rear wheel to lift off the
ground.
When you brake, bear in mind
that ABS control cannot be relied
on in all circumstances to prevent
the rear wheel from lifting clear of
the ground.

What is the design
baseline for BMW
Motorrad ABS?Within the limits imposed by
physics, BMW Motorrad ABS en-
sures directional stability on any
surface. The system is not op-
timised for special requirements
that apply under extreme com-
petitive situations off-road or on
the track.Special situationsThe speeds of the front and rear
wheels are compared as one
means of detecting a wheel's
incipient tendency to lock. If the
system registers implausible val-
ues for a lengthy period the ABS
function is deactivated for safety
reasons and an ABS fault mes-
sage is issued. Self-diagnos-
is has to complete before fault
messages can be issued.
In addition to problems with the
BMW Motorrad ABS, exceptionalriding conditions can lead to a
fault message being issued.
Exceptional riding
conditions:
Riding for a lengthy period with
the front wheel lifted off the
ground (wheelie).
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.
Rear wheel locked for a lengthy
period, for example while des-
cending 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
ABS permits must not be used
as an excuse for careless riding.
ABS is primarily a means of en-
suring a safety margin in genuine
emergencies.
Take care when cornering. When
you apply the brakes on a corner,
