wheel off the
ground and measure from a point
close to the rear wheel
axle to a point on the rear fender
of the vertical.
Measurement A ... (e.g.) 610mm
the bike off the stand and put on
Sit on the bike in a central position

the other on the
floor just for balance not weight
You will need someone to take the
from the same two points.
Measurement B ... (e.g.) 510mm
610 - 510 = 100, (Race Sag : 100mm)
static sag is measured when the
rider is off
the bike and it is standing on its
own free weight.
You measure the same two points
again, and then
subtract C from A this will give
you the static sag.
Measurement C ... (e.g.) 585mm
610 - 585 = 25, (Static Sag : 25mm)
sag should be set Midway
between these measurements
which is a good starting point.
125 - 500cc 15 - 30mm
60 - 100cc 15-25mm
sag should be set at between 25
of the bikes' full suspension travel.
125 - 500cc 90 - 100mm
80 - 100cc 80 - 90mm
60cc 50 - 60mm
