REAR SUSPENSION SET UP
First check the spring rate-chart on this page to make sure that the spring tted on
your Tazer MX is within range for your rider weight. If the spring is too hard or too
soft you will need to change it. Please see our Tech Videos section on our website
to see how to change the coil on your shock.
SPRING RATES AS STANDARD
PRO MODEL: Öhlins TTX22M COIL
Size S/M: 480 lb
Size L/XL: 548 lb
Shock travel: 155mm (6.1"). Shock stroke: 55mm (2.15"). Shock sag: 30% when
sitting on the bike. Shock preload: Min-1.5 turns / Max-5 turns.
STEP 19
SETTING SHOCK SAG
Just as you did with your forks you now need to
set the sag on your rear shock. The optimal sag on
your rear shock is 30% of the piston’s movement
inside the shock body (stroke) for both the Öhlins
equipped PRO model and the DVO on the EXPERT.
The distance between the two shock mounting bolts
(eye-to-eye) without a rider on the bike is 185mm for
both shocks. Sag at 30% (of the piston) equates to a
16mm reduction in the eye-to-eye measurement. So
the correct eye-to-eye measurement for 30% sag on
both of these shocks is 169mm (185-16 = 169mm).
With the help of a friend, sit in a normal riding position
in full riding gear on the bike, pedals level. Bounce up
and down on the bike a few times and then gently sit
back down. While still sitting on the bike, and with the
shock slightly compressed (sag), measure the length
of the shock (eye-to-eye) and record that number (A).
To check the amount of sag just minus the original
number from the new measurement, that will be your
sag measurement. If the eye-to-eye measurement
is 169mm that will give you a sag measurement of
16mm, which gives you the exact 30% sag rate you
are looking for.
While adjusting your rear shock sag, keep in mind
that you must keep your total turns of spring preload
at a minimum of two turns and a maximum of ve
turns. If your sag number is higher than 30%,
increase the spring preload by turning the preload
collar clockwise (2-5 turns) (B). If your sag number
is lower than 30%, decrease the spring preload by
turning the preload collar counterclockwise (minimum
of two turns from base). Check the sag measurement
again and adjust as necessary. If you cannot get the
correct sag you will probably need a different spring
rate for your bike.
