down again.Lengthy periods of disuseIf it is going to be out of use for
more than two months, support
the motorcycle in such a way
that the wheels are not taking
any weight, for example by lifting

Check the air pressures before
removing the motorcycle from
the auxiliary stand. You can use
the pressure gauge on the pneu-
matic pump for this check.Adjusting air pressure in

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,
the motorcycle's weight and

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 the air pressure in the Air
Damping System, the damp-
ing characteristic and the tyre
pressures to suit total weight.
Note the maximum permissible
payload of the luggage carrier.

WheelsRecommended tyresFor each size of tyre BMW Mo-
torrad tests and classifies as
roadworthy certain makes. BMW
Motorrad cannot assess the suit-
ability or provide any guarantee
of road safety for other tyres.
BMW Motorrad recommends
using only tyres tested by BMW
Motorrad.
