9.3Checking the basic suspension setting with the rider's weight
Info
When adjusting the basic suspension 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 off-road motorcycles are adjusted for a standard rider weight (with full protective clothing).
Guideline
Standard rider weight 75… 85 kg (165… 187 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.
9.4Compression damping of shock absorber
The shock absorber can regulate compression damping separately in the low-speed and high-speed ranges (Dual Compression Control).
The terms low-speed and high-speed refers to the movement of the shock absorber during compression and not to the riding speed of
the motorcycle.
Changes in the settings in the low-speed range have an impact on the high-speed range and vice versa.
9.5Adjusting the high-speed compression damping of the shock absorber
Danger
Danger of accidentsDisassembly 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 high-speed setting can be seen during the fast compression of the shock absorber.
