OverviewChapter 2 of this Rider's Manu-
al will provide you with an initial
overview of your motorcycle. All
maintenance and repair work on
the motorcycle is documented in
Chapter 11. This record of the
maintenance work you have had
performed on your motorcycle is
a precondition for generous treat-
ment of goodwill claims.
When the time comes to sell
your BMW, please remember
to hand over this Rider's Manu-
al; it is an important part of the
motorcycle.Abbreviations and

ABSAnti-lock brake system
Air Damping SystemThis motorcycle has an air-filled
rear suspension system. This Air
Damping System, as it is known,
does not work in the same way
as a conventional steel-spring
shock-absorber system. The de-
tailed description of this system
starts on page ( 34).

ChecklistUse the following checklist to
check important functions, set-
tings and wear limits before you
ride off.
Brakes
Brake-fluid levels, front and rear
Clutch
Clutch fluid level
Damping-characteristic adjust-
ment and air pressure in the Air
Damping System
Tyre-tread depth and tyre
pressures
Cases correctly installed and
luggage secured
At regular intervals:
Engine oil level (every refuelling
stop)
Brake-pad wear (every third
refuelling stop)
Tension and lubrication of the
drive chain
StartingSide standYou cannot start the motorcycle
with the side stand extended and
a gear engaged. The engine will
switch itself off if you start it with
the gearbox in neutral and then
engage a gear before retracting
the side stand.GearboxYou can start the engine when
the gearbox is in neutral or if you
pull the clutch with a gear en-
gaged.
Starting engine.Kill switch in operating position
(run).
Gearbox lubrication is en-
sured only when the engine
is running. Inadequate lubrica-
tion can result in damage to the
gearbox.
Do not allow the motorcycle to
roll for a lengthy period of time or
push it a long distance with the
engine switched off.
Switch on the ignition.
Pre-ride check is performed.

546zRiding

Keep to the specified engine
speeds for running in.
During the running-in phase,
do not exceed the speed limits
specified for the various gears.
Maximum speeds during
running-in period
max 35 km/h (1st gear)
max 55 km/h (2nd gear)
max 75 km/h (3rd gear)
max 95 km/h (4th gear)
max 110 km/h (5th gear)
No full-load acceleration.
Avoid low engine speeds at full
load.
Do not omit the first inspection
after 500 - 1200 km.Brake padsNew brake pads must "bed
down" and therefore do not
achieve their optimum friction
levels during the first 500km. You can compensate for
this initial reduction in braking
efficiency by exerting greater
pressure on the levers.
New brake pads can ex-
tend stopping distance by a
significant margin.
Apply the brakes in good time.
TyresNew tyres have a smooth sur-
face. This must be roughened by
riding in a restrained manner at
various heel angles until the tyres
are run in. This running in pro-
cedure is essential if the tyres are
to achieve maximum grip.
Tyres do not have their full
grip when new and there
is a risk of accidents at extreme
angles of heel.
Avoid extreme angles of heel.
Riding off-roadTyre pressures
Tyre pressures reduced for
off-road riding impair the
motorcycle's handling character-
istics on surfaced roads and can
lead to accidents.
Always check that the tyre pres-
sures are correct.
Dirt or mud on brakes
When riding on loose sur-
faces or muddy roads, the
brakes may fail to take effect
immediately because of dirt or
moisture on the discs or brake
pads.
Apply the brakes in good time
until the brakes have been
cleaned.
The brake pads will wear
more rapidly if you ride fre-
quently on unsurfaced tracks or
poor roads.
Check the thickness of the brake
549zRiding

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.
