ESA Electronic Suspension
Adjustment.
DWA Anti-theft alarm system.
ABS Anti-lock braking system.Custom equipmentWhen you ordered your BMW
motorcycle, you chose various
items of custom equipment.
This Rider’s Manual describes
optional extras (OE) offered by
BMW and selected optional
accessories (OA). This
explains why the manual may
also contain descriptions of
equipment which you have not
ordered. Country-specific
deviations from the motorcycle
illustrated are also possible.If your BMW contains equip-
ment which is not described in
this Rider’s Manual, this will be
described in separate operat-
ing instructions.
Technical dataAll dimensions, weights and
power ratings stated in the
Rider’s Manual are quoted to
the standards and comply with
the tolerance requirements of
the Deutsche Institut für
Normung e. V. (DIN). Versions
for individual countries may
differ.
CurrencyThe high safety and quality
standards of BMW motorcy-
cles are maintained by con-
stant development work on
designs, equipment and
accessories. Because of this,
your motorcycle may differ
from the information supplied

errors and omissions be
entirely ruled out. We hope
you will appreciate that no
claims can be entertained on
the basis of the data, illustra-
tions or descriptions in this
manual.

Operation348
Incorrect tyre pressure
reduces the operating life
of the tyres.
Ensure that the tyres are at the
correct pressure.c
The tyre pressures required
can be found in the technical
data (b 126).
At high road speeds, tyre
valves have a tendency
to open as a result of centrifu-
gal force.
To avoid sudden loss of tyre
pressure, use a metal valve
cap with rubber sealing ring on
the rear wheel and tighten it
securely.c
