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 telescopic 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).
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 illustrations.
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 KTM 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.
