TUNING THE CHASSIS
30
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 a standard rider weight
(with full protective clothing).
Guideline
Standard rider weight
75… 85 kg (165… 187 lb.)
–
If the rider's weight is above or below the standard range, the basic setting of the
suspension 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 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, affects the compression when landing after a jump: the rear wheel suspension compresses more
quickly.
The low-speed setting, for example, affects the compression when riding over long ground swells: the rear wheel suspension com-
presses 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
Danger of accidents
Disassembly of pressurized parts can lead to injury.
–
The shock absorber is filled with high density nitrogen. Adhere to 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.

–
Turn adjusting screw
clockwise with a screwdriver up to the last perceptible
click.
Info
Do not loosen fitting
.
–
Turn counterclockwise by the number of clicks corresponding to the shock absorber
type.
