Measuring wheel track offset
Place motorcycle on level ground on centre
stand.
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 the supports in on
the other side.
Adjust support (1) so that the measuring plane is
as close as possible to the wheel centreline. The
gauge must slide freely up to the motorcycle.
Adjust measuring stops (arrows) until they con-
tact the rim - not the tyre.
Attach hook (2) to wheel spoke to secure the
gauge firmly to the wheel.
Align front wheel parallel with the gauge.
Measure distance between outer edge of gauge
and wheel rim, using depth gauge (3) or ruler,
and make a note of the dimension.
Calculate wheel track offset S:
Wheel track offset S is the distance to left or right
between the longitudinal axes of the front and
rear wheels.
Permissible
wheel track offset (S): ................... 9 mm (0.35 in)
Key to measurement result:
Minus sign = track offset to left
Plus sign = track offset to right
