10 TUNING THE CHASSIS
24
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 25… 35 kg (55… 77 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 Air suspension AER 35 (50 SX)
Air suspension WP Performance Systems AER 35 is used in the fork.
In this system, suspension is located in the left fork leg and damping in the right fork leg.
As fork springs are no longer required, a significant weight advantage is achieved when compared to conventional forks. The response
on slightly uneven surfaces is significantly improved.
In normal driving mode, suspension is provided exclusively by an air cushion. A steel spring is located in the left fork leg as an end
stop.
Info
If the fork is frequently overloaded, then the air pressure in the fork must be increased to avoid damage to the fork and frame.
The air pressure in the fork can be quickly adjusted for the rider's weight, surface conditions and the rider's preference using a fork
pump. The fork does not have to be detached. The time consuming mounting of harder or softer fork springs is not required.
If the air chamber loses air due to a damaged seal, the fork will still not sag. In this case the air is retained in the fork. The suspen-
sion travel is maintained as far as possible. The damping becomes harder and the riding comfort reduces.
The rebound damping can be adjusted.
The rebound adjustment is located at the upper end of the right fork leg.
10.3 Compression damping of the shock absorber (50 SX)
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 quickly.
The low-speed setting, for example, has an effect 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 gradual. Thus, changes in
the high-speed range affect the compression damping in the low-speed range and vice versa.
