Wheel offset
-
measuring
Motorcycle geometry
can
be measured very simply with
BMW
wheel
offset gauge 36 3
920.
Deviations
and changes
resulting from
an
accident which
affeclthe
frame
ortelescopic
forks usually have
a
highly
marked
effect on
road behaviour. Measuring wheel
offset will
reveal
wh ether
hte
motorcycle's
geometry
has
altered.
Place the motorcyele
on a level floor or
lifting platform
.
Apply
the wheel offset gauge to the
right-hand
side of the
motorcyele.
Set the
adjustable supports so as
to locate
the
measuring
plane as elose
to
the wheel centre as possible
and so
that
the
gauge
can slide
freely
along the
motorcycle.
-
The
measuring
stops
must
only make contact with
the
outer
edge
ofthe
rim
and notthe tyre.
Insertthe pull hook in
the cast or wire spoke and carefully pull the gauge to
the
rear wheel until it is
firmly
attached.
Measure and
calculate wheel offset
"S" as
shown on
page
46-79.0.
The
exterior
rim
width
for
K
models is:
Frontwheel:82
mm
±
0.5 mm
Rearwheel:
89
mm
±
0.5
mm
These
figures are
only
outline values, and are
not intended
as a substitute
for
actual measurements.
Maximum permitted wheel
offset:
