Motion Control was introduced for model year
2005.
Motion Control (MoCo) is a sealed
damping system that utilizes a revolutionary spring tube and 'poker' to
allow for fully adjustable, on-the-fly, compression damping, lockout, and
platform adjustments.
MoCo can be activated by either the crown
mount adjuster knob, or with the PopLoc, PopLoc Dual or PushLoc handlebar
mounted remote levers.
By closing the compression damper (blue
knob) the fork can either be:
1. Locked
out (with a slight amount of movement for small bump compliance)
or
2. Adjusted to a wide range of
'platform' settings by adjusting the gold Floodgate knob (or internal
Floodgate adjuster - 2.5mm hex) clockwise = more platform counterclockwise
= less platform, Platform functions only when the compression damper is in
the closed, or locked position.
Motion Control allows you the rider to
control your ride, making your bike more efficient and fun.
Motion Control Damping Set Up
The Motion Control Damping system allows riders to quickly
adjust the feel and performance of their suspension to
match riding conditions without requiring pumps or tools. This system provides for wide-ranging control of compression
and rebound damping as well as ‘Lock’ threshold
sensitivity.
Proper setup of the Motion Control Damping system provides
a range of options for efficient yet comfortable
performance. The instructions below describe setup and operation for both
crown and remote activated forks.
OPEN’ COMPRESSION
FLOODGATE ADJUSTMENT
All forks with Motion Control Damping allow for
fine-tuning of the ‘Lock’ setting. The rider can
choose the point at which the ‘Lock’ setting can 'blow-off' and become
active to force inputs such as bumps or rocks. This
adjustment is made using the Floodgate. Depending upon
fork model, the Floodgate is adjusted either internally (requires a
2.5mm hex wrench) or externally with the gold ‘Gate’
adjuster. For crown mounted adjusters, hold the
adjuster in the ‘Lock’ position while adjusting the
internal Floodgate.
NOTE: THE FLOODGATE IS INTENDED TO ADJUST THRESHOLD OF ‘LOCK’ BLOW-OFF
IN THE ‘LOCK’ MODE ONLY.
WHEN PERFORMING FLOODGATE ADJUSTMENTS, ENSURE THAT THE MOTION CONTROL
SYSTEM IS ADJUSTED
TO ‘LOCK.’
Under ‘Lock’, the maximum Floodgate setting results in a
fork with minimal movement while the minimum Floodgate
setting results in increased fork movement.
NOTE: FOR MAXIMUM FORK SENSITIVITY AND MOVEMENT, RETURN THE FORK TO THE
‘OPEN’ POSITION.
Floodgate settings should be used to adjust suspension
compliance to medium sized bumps and resistance to
rider induced suspension movement (referred to as “bob”) in the ‘Lock’ mode. When properly tuned, the Motion Control System
will resist "bob," but provide controlled suspension
action in rough or aggressive terrain. Under ‘Lock’,
heavier riders may find better performance with maximum Floodgate
settings, while lighter riders may find minimum
Floodgate settings work best. Experiment with higher
or lower Floodgate settings while on the trail to optimize your
fork for your riding style and performance
preferences.

Use the chart on the right below to establish an
initial Floodgate setting.
All settings from Maximum Floodgate (or full
clockwise)

TIP: THE REBOUND ADJUSTER ON THE BOTTOM
RIGHT FORK LEG CAN BE USED TO ADJUST INTERNAL FLOODGATE
MODELS. GENTLY PULL DOWNWARD ON THE REBOUND ADJUSTER FOR REMOVAL. REMOVE
THE GOLD ‘GATE’ DUST CAP AND INSERT THE 2.5MM HEX END OF
THE REBOUND ADJUSTER INTO THE FLOODGATE. DON'T FORGET TO RE-INSTALL THE
ADJUSTER AFTER USE!

OMPRESSION ADJUSTMENT
Some fork models also feature adjustable
compression damping. Increased compression decreases
fork movement in the ‘Open’ position. Compression adjustment can be used
to help combat brake dive and "squatting" under hard
cornering.
For crown activated forks, compression damping
increases to ‘Lock’ as the crownmounted actuator
rotates 90 degrees clockwise. Position the actuator anywhere within
the range from ‘Open’ to ‘Lock’ to suit the desired
level of compression damping. Forks equipped with the
PopLoc Adjust provide compression damping adjustment for the ‘Open’ position. Turning the blue adjuster on the PopLoc adjust
clockwise increases compression damping for the ‘Open’
position. The PopLoc lever features gradients to help
illustrate the current level of compression. Eight complete turns of
adjustment are
provided.

IP: ADJUSTING COMPRESSION ON FORKS EQUIPPED WITH
POPLOC ADJUST IS BEST DONE WITH THE FORK
IN
‘L
OCK’ POSITION.

OTE:
THE COMPRESSION SETTING DOES NOT
ADVERSELY EFFECT YOUR FORK'S PERFORMANCE OVER HIGH
SPEED IMPACTS
.
External Rebound
Adjustment
Rebound damping controls the speed at which a
fork returns to its full extension following
compression. Located at the bottom of the right fork leg is the rebound
adjuster knob. Turning the adjuster in the direction
indicated by the "rabbit" on the rebound speed decal
decreases rebound damping, causing the fork to return to full extension faster. Turning the adjuster in the direction indicated
by the "turtle" increases rebound damping, slowing the
return of the fork to full extension.Excessive rebound
damping will cause the fork to "pack up" over successive bumps,
reducing travel and causing the fork to bottom out.
Set your fork to rebound as fast as possible without
"topping out" or kicking back. This allows your fork to follow the
contours of the trail, maximizing stability, traction
and control.
Setting Sag
RockShox forks are designed to sag when you are
sitting on your bike. Sag is the compression of the
fork caused by the rider's weight. Proper sag allows the front
wheel to follow the contour of the terrain as you
ride.
To measure sag, set the fork to maximum travel
(140 mm). Install a zip tie on the upper tube of the
fork flush against the wiper seal. Sit on the bike with normal riding
apparel. Step off the bike, and measure the distance
between the wiper seal and the zip tie. This is your
sag. The sag should be between 15 and 25 percent of maximum travel. If
you're unable to achieve optimum sag you may need to
change the fork's spring.
