Adjusting The Suspensions According To Particular Track Conditions - Husqvarna TC 450 Workshop Manual

SETTINGS AND ADJUSTMENTS

Adjusting the suspensions according to particular track conditions

The following information is a useful guide for setting up the suspensions ac-
cording to the road conditions.
Always start from the standard calibration before making any change on the
suspensions. Afterwards, increase or decrease the adjusting clicks one at a time.
HARD GROUND
Fork: softer compression adjustment.
Shock absorber: softer compression adjustment.
The softer adjustment for the two suspensions is also used both in compression
and in extension when driving at top speed, in order to have better grip of the tires.
SANDY GROUND
Fork: have a harder compression adjustment, or replace the standard spring
with a harder one, and make a softer compression adjustment and a harder
extension adjustment at the same time.
Shock absorber: have a harder compression, and expecially a harder extension
adjustment. Work on the spring preload to lower the motorcycle rear side.
MUDDY GROUND
Fork: have a harder compression adjustment, or replace the standard spring
with a harder one.
Shock absorber: have a harder compression and extension adjustments, or
replace the standard spring with a harder one. Work on the spring preload to lift
the motorcycle rear side.
We advise replacing the springs of both suspensions to compensate the weight
increase due to the piling of the mud.
NOTE:
When the fork results as either too soft or too hard for any adjustment conditions,
check the oil level inside the forkrod.
The level can either be too low or too high. Remember that too much oil inside
the fork will involve a more frequent air drainage. When the suspensions do not
react to the changes of calibration, check that the adjusting units are not blocked.
The standard calibrations, the available springs and the adjustment procedures
are shown on the next pages.
