MAINTENANCE WORK ON CHASSIS AND ENGINE

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 pre-
load 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
[2]
changes the spring preload by approx-
imately 2 mm.
Loosen the allan head screw
[1]
at the adjustment ring
[2]
. Use the special
wrench
[3]
from the tool set to turn the adjusting ring as required. Place the
adjusting ring in a suitable position, and tighten the allan head screw with
8 Nm (6 ft.lb).

Checking the rubber ring of the 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 wide. Have the rubber
ring replaced in a KTM garage when compaction due to wear has exceeded
the limit.
NOT REPLACING THE RUBBER RING IN TIME CAN RESULT IN DAMAGE TO THE
SHOCK ABSORBER.
THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGHLY COM-
PRESSED NITROGEN. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO
DO ANY MAINTENANCE WORK YOURSELF. SEVERE INJURIES COULD BE THE
RESULT.
Lubricating the shock absorber linkage
The bearings in the rocker arm must be greased in regular intervals. For this
purpose, a grease nipple
[4]
is mounted on the rocker arm.
AFTER EACH TIME THE MOTORCYCLE IS WASHED, IT IS ESPECIALLY IMPORTANT
TO GREASE THE GREASE NIPPLE TO PUSH ANY WATER OUT OF THE BEARINGS.
