Changing the spring preload of the shock absorber

KTM sets the shock absorber for a driver only, weighing approximately 75
kg (165 lb). If you want to take a passenger with you, of if you weigh con-
siderably more or less than 75 kg (165 lb), you should change the spring
preload
A
accordingly. This is easily done.
NOTE:
– Before changing the spring preload note down the basic setting, e.g.
how many threads are visible above the adjusting ring.
– One rotation of the adjusting ring
approximately 1,75 mm (0,07 in).

Checking rubber ring on the WP rear shock absorber
A rubber ring mounted on the rear shock absorber serves as a vibration
damper. This ring gets pressed together with time and loses its shock
absorbing quality.
Measure the distance between the two discs at various points around their
circumferences. The space should be at least 2.5 mm (0,1 in) wide. Have
the rubber ring replaced by an KTM dealer when compaction due to wear
has exceeded this lower limit.
