Headlight basic setting
\f Note:
Do not prop the motorcycle on
the centre or side stand.
 Check tyre pressures and
correct if necessary.
 Set the spring-strut adjuster
to the position for one-up
riding
 Position the motorcycle on a
level surface 10 metres
(headlight) from a light-col-
oured wall, and with the
rider's weight (approx. 85 kg)
on the seat
 Measure the distance H from
the ground to the centre of
the headlight
 Transfer this height H to the
wall and draw a cross on the
wall at this point 
Draw a second cross
(x = 25 cm) lower
 Switch on the low-beam
headlight beam
 Align the headlight in such a
way that the light-dark cut-off
starts in the middle of the bot-
tom cross and rises to the
right to the height of the upper
cross, before dropping again.
\f Note:
Have the headlight basic set-
ting checked by a specialist
workshop, preferably an
authorised BMW motorcycle
dealer.

Wheels
Checking tyre pressures
d Warning:
Incorrect tyre pressures have
a considerable influence on
handling and on tyre life.
Adjust tyre pressures to suit
total weight. Never exceed ei-
ther the motorcycle ’s gross
weight or the individual wheel
load limits (b 47). –
When tyres are cold:
 Remove valve caps
 Check/correct tyre pressure
Tyre pressures: Front Rear
One-up 2.2 bar 2.5 bar
Two-up 2.5 bar 2.7 bar
Two-up
with luggage 2.5 bar 2.9 bar
 Fully tighten valve caps
Fully tightening valve caps
d Warning:
At high road speeds, tyre
valves have a tendency to
open as a result of centrifugal
force.
Use only metal valve caps
with rubber seals.
Valve caps that are screwed
on well prevent air from es-
caping suddenly.

Running in
Running in new brake
pads
d Warning:
New brake pads must "bed
down" and therefore do not
achieve their optimum friction
levels during the first 500 km.
This slight initial reduction in
braking efficiency can be
compensated for by exerting
greater pressure on the lever.
Try to avoid all unnecessary
hard braking during this initial
period.
e Attention:
Comply with the notes on BMW
Integral ABSOE (b 68-75).
Running in new tyres
d Warning:
New tyres have a smooth sur-
face. This must be roughened
by riding in a restrained man-
ner at various heel angles
until the tyres are run in.
This running in procedure is
essential if the tyres are to
achieve maximum grip.
