FORK REBOUND ADJUSTMENT
The rebound hydraulic braking system determines the fork rebound stroke.
The degree of rebound hydraulic braking can be adjusted to suit the rider
and/or the installed spring rate.
KAYABA USD FORK
The adjusting screw (1) is in the lower part of the fork foot. Use a screwdriver.
Turn it clockwise to increase braking, or anti-clockwise to reduce it. There
are a total of 21 clicks available.
WARNING
Do not touch the hexagon nut (2) as it is not needed to alter rebound braking.
WARNING
Before starting, tighten the adjuster from the standard position to “fully
closed” while counting the clicks. Write down the number of clicks counted
so that you can restore the standard adjustment if necessary.
The clicks are normally indicated from the “fully closed” position.
Both tubes must be adjusted in the same way.
STANDARD ADJUSTMENT
MX 12 clicks from fully closed
EN 12 clicks from fully closed
SMR 10 clicks from fully closed
SMK
12 clicks from fully closed
VARYING PRE-LOAD AND REPLACING FORK SPRINGS
To vary the spring pre-load on these forks, you must partly disassemble them
(see the specific manual of the fork fitted on the motorcycle).
You should absolutely not vary the spring pre-load on forks fitted by TM
Racing.
If necessary, replace the springs with others that have a different rate.
WARNING
For further, more detailed information about the forks, see the instructions
supplied by the fork manufacturer.
