8.1Jacking up the motorcycle
600034-10
Note
Danger of damage Danger of damage by the vehicle running away or falling over.
– Always place the vehicle on a firm and even surface.
– Jack up the motorcycle at the motor protection device near the swinging fork. The
wheels must no longer touch the ground.
Work stand (54829055000)
– Secure the motorcycle against falling over.
8.2Removing the motorcycle from the work stand
Note
Danger of damage Danger of damage by the vehicle running away or falling over.
– Always place the vehicle on a firm and even surface.
– Remove the motorcycle from the work stand.
– Remove the work stand.
8.3Checking 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, swing arm and frame, the basic set-
tings of the suspension components must match your body weight.
– As delivered, KTM offroad motorcycles are adjusted for a standard rider weight (with full protective clothing).
Specification
Standard rider weight 75… 85 kg (165.34… 187.39 lb.)
– If your weight is above or below the standard range, you have to adjust the basic setting of the suspension components accord-
ingly.
– Small weight differences can be compensated by adjusting the spring preload, but in the case of large weight differences, the
springs must be replaced.
8.4Compression damping of shock absorber
600013-10
The compression damping can be adjusted via an opening on the left side of the
rear tank.
The shock absorber can regulate compression damping in low- and high-speed range
separately (Dual Compression Control).
The term low and high speed refers to the movement of the shock absorber during com-
pression and not the riding speed of the motorcycle.
The low- and high-speed technology works non-specifically.
8.5Adjusting compression damping of shock absorber
Danger
Danger of accidents The shock absorber is under high pressure.
– The shock absorber is filled with highly compressed nitrogen, so never dismantle the shock absorber or carry out any main-
tenance on it yourself.
Info
The compression damping is differentiated into a low speed and high speed setting.
The low-speed setting can be seen during the slow to normal compression of the shock absorber.
The high-speed setting can be seen during the fast compression of the shock absorber.
