Measuring wheel track offset

L
Note:
Wheel track offset S is the distance to left or right
between the longitudinal axes of the front and rear
wheels.
•
Place the motorcycle on its main (centre) stand
on a flat, level surface.
•
Measure wheel rim width at front and rear and
make a note of the figures.
•
Place track alignment gauge,
BMW No. 36 3 920, against the left or right side
of the motorcycle.
L
Note:
In order to use the track alignment gauge on either
the left or right side, simply screw in the supports (1)
on the other side.
•
Adjust supports (1) so that the measuring plane
is as close as possible to the wheel centreline.
The gauge must slide freely up to the motorcy-
cle.
•
Adjust measuring stops (arrows) until they con-
tact the rim – not the tyre.
•
Connect hook (2) to a wheel spoke and use it to
pull the gauge firmly up to the wheel.
•
Align front wheel parallel with the gauge.
•
Release tension in the track alignment gauge by
raising it by approx. 5 mm (0.2 in) at the front and
lowering it again.
3
•
Using a depth gauge (3), measure the distance
from the outer edge of the gauge to the front
wheel rim at the front and rear of the wheel and
make a note of the figures.
•
Subtract the width of the track alignment gauge
from the measured values.
L
Note:
The average of these two values is distance B.
•
Calculate the average.
