ADJUSTING RIDE QUALITIES:
2001 MARS forks offer a wide adjustment range to suit individual riding preference and rider weight
by simply changing the air pressure and spring rate.
Compression Spring Fine-Tuning
Fine tuning adjustments are made by adjusting the air pressure and changing the spring. Use the
chart below as a starting point for finding the proper air spring based on rider weight.

Air/coil spring rate tuning
All 2001 MARS forks use a combination of air and a coil spring. The air spring is adjustable via a
Schraeder valve located on top of the left leg. See Figure 3. The positive coil spring can also be
switched with stiffer or softer versions to accommodate for different rider styles and terrain.
There’s also a coil negative spring, but it is available in one rate only and is designed to be pre-
loaded automatically as the positive air spring pressure
is increased (in other words, you dont need to do any-
thing to tune it).
Compression Damping Tuning:
To adjust the MARS Elite: Figure 3
Simply rotate the compression-damping knob located
on top of the right leg and crown. Rotating the knob
clockwise will increase the damping, rotating the knob
counter clockwise will reduce the damping. Excessive
damping will give you a harsh ride over sharp bumps like
rocky sections, but will feel good in large hits like G-
outs. Insufficient compression damping will bottom out
in the large hit G-outs and bob a little while climbing
but feel plush on the sharp hits.
To adjust the MARS Super: Figure 4
Remove the Anti-Bob compression damping assembly
from the top of the right leg. Adjust the setscrew on
the valve seat in to increase compression damping and
out to reduce the compression damping. Try adjusting
one half turn at a time.
Note: Compression and rebound damping on the MARS is
factory pre set.
