2 SPRI G PRELOAD
Spring preload and rear ride height
When you set the spring preload you move the
spring seat. This will decrease or increase the
initial spring force, which will lower or raise the
motorcycle rear ride height.
The spring preload is important for the shock
absorber’s performance. If the preload is
incorrectly set, any other adjustments will not
help to get the intended performance from
the shock absorber. The spring preload is the
difference between the free spring length and
the installed spring length.
A Free spring length
B Installed spring length
Shock absorber fully extended
A - B = Spring Preload
Set the spring preload
Hydraulic spring preload adjuster
Turn the hexagon screw or the knob on the
hydraulic adjuster to set the spring preload. Turn
clockwise to increase the spring preload and
turn counter clockwise to decrease the spring
preload.
Mechanical spring preload adjuster
Use two C-spanners. Hold the lock nut with one
C-spanner and turn the spring platform to the
desired position with the other C-spanner.
