10 TUNING THE CHASSIS
10.1
10.2
The compression damping of the shock absorber is divided into two ranges: high-speed and low-speed.
High-speed and low-speed refer to the compression speed of the rear wheel suspension and not to the vehicle
speed.
The high-speed compression adjuster has an effect, for example, when landing after a jump: the rear wheel sus-
pension compresses quickly.
The low-speed compression adjuster has an effect, for example, when riding over long ground swells: the rear
wheel suspension compresses slowly.
These two ranges can be adjusted separately, although the transition between high-speed and low-speed is grad-
ual. Thus, modifications in the high-speed range affect the compression damping in the low-speed range and vice
versa.

Checking the basic chassis setting with rider's weight
Info
When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

Compression damping of the shock absorber
Adjusting the low-speed compression damping of the shock absorber
Caution
Risk of injury Parts of the shock absorber will move around if the shock absorber is detached incorrectly.
The shock absorber is filled with highly compressed nitrogen.

Please follow the description provided. (Your authorized KTM workshop will be glad to help.)
Info
The effect of the low-speed compression adjuster can be seen in slow to normal compression of the shock
absorber.
–
For optimal motorcycle riding characteristics and to avoid
damage to forks, shock absorbers, link fork and frame, the
basic settings of the suspension components must match the
rider's weight.
–
As delivered, KTM offroad motorcycles are adjusted for an
average rider's weight (with full protective clothing).
Guideline
Standard rider weight
–
If the rider's weight is above or below this range, the basic set-
ting of the suspension components must be adjusted accord-
ingly.
–
Small weight differences can be compensated by adjusting
the spring pretension of the shock absorber, but in the case of
large weight differences, the springs must be replaced.
