10 TUNING THE CHASSIS 26
10.1 Checking the basic chassis setting with the rider's weight
Info
When adjusting the basic chassis setting, first adjust the shock absorber and then the fork.

– For optimal motorcycle riding characteristics and to avoid damage to forks, shock
absorbers, swingarm 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 45… 55 kg (99… 121 lb.)
– If the rider's weight is above or below this range, the basic setting of the suspen-
sion components must be adjusted accordingly.
– Small weight differences can be compensated by adjusting the spring preload, but
in the case of large weight differences, the springs must be replaced.
10.2 Compression damping of the shock absorber
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 setting, for example, has an effect on the landing after a jump: the rear wheel suspension compresses more quickly.
The low-speed setting, for example, has an effect when riding over long ground swells: the rear wheel suspension compresses more
slowly.
These two ranges can be adjusted separately, although the transition between high-speed and low-speed is gradual. Thus, changes in
the high-speed range affect the compression damping in the low-speed range and vice versa.
10.3 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 low-speed setting can be seen during the slow to normal compression of the shock absorber.
