Checking The Basic Setup Of The Telescopic Fork; Changing The Spring Preload On The Telescopic Fork; Replacing Fork Springs - HUSABERG "05 Owner's Manual

MAINTENANCE WORK ON CHASSIS AND ENGINE
The riding sag should lie between 90 and 105 mm.
If the riding sag is less than 90 mm, the spring is too hard (the spring rate
is too high). If the riding sag is more than 105 mm, the spring is too soft
(the spring rate is too low).
The spring rate is written on the outside of the spring (e.g. 88/250). The
type number of the shock absorber is embossed on the bottom of the tank.
The illustrations show which spring should be installed. The standard spring
is shown in bold print. After installing a different spring, readjust the sta-
tic sag to 35 mm (± 2 mm).According to our experience, the damping rate
of the compression stage can remain unchanged. The damping rate of
the rebound stage can be reduced by a few clicks for a softer spring or
increased by a few clicks for a harder spring.
CHECKING THE BASIC SETUP OF THE TELESCOPIC
FORK
The precise riding sag of the telescopic fork cannot be determined for
various reasons. Similar to the shock absorber, smaller deviations in your
weight can be compensated by adjusting the spring preload. However, if
your telescopic fork bumps frequently (hard end stop during compression),
you should install harder fork springs to avoid damaging the telescopic
fork and frame.
CHANGING THE SPRING PRELOAD ON THE TELES-
COPIC FORK
The telescopic forks for these models must be partly disassembled to adjust
the spring preload (see WP manual). Pretension spacers are available in
heights of 1.5, 2.5 and 5 mm (see spare parts catalog). The fork springs
may not be pretensioned by more than 20 mm.
NOTE: WP precisely adjusts the spring pressure by
inserting pretension spacers. Fluctuations in production are
compensated with pretension spacers in various heights.
This can cause the fork springs in the fork legs to have
different degrees of pretension. Fork springs and pretension
spacers should always stay together.

REPLACING FORK SPRINGS

If you weigh less than 70 kg or more than 80 kg, you should install the
respective fork springs. The correct spring rate is shown in the illustra-
tions. The standard spring is shown in bold print. The type number of the
telescopic fork is embossed on the caps on the top of the telescopic fork.
If you are uncertain which spring to use, contact your Husaberg
workshop.
According to our experience, the damping rate of the compression stage
can remain unchanged. The damping rate of the rebound stage can be
reduced by a few clicks for a softer spring or increased by a few clicks for
a harder spring.
