Overview of the shock absorber springs
The spring rate is written on the outside of the spring (e.g. 35-215). The type
number of the shock absorber is embossed on the top.
The illustration on the left shows which spring should be installed. The stan-
dard spring is shown in bold print.
After installing a different spring, readjust the static sag to 30-35 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 vari-
ous reasons. 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.
Overview of the telescopic fork springs
If your child weights less than 50 kg or more than 60 kg, have your KTM work-
shop mount suitable fork springs. The illustration on the left shows the cor-
rect spring rate. The standard spring is shown in bold print.
The type number of the telescopic fork is embossed on the inside of the fork
leg.
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.
