Changing the spring preloading of the shock absorber
KTM sets the shock absorber for a driver with a weight of approximately
75 kg (165 lb). If the weight of the driver is more or less than 75 kg (165
lb), you should change the spring preloading
A accordingly. This is easily
done.
NOTE:
– Before changing the spring preload note the basic setting, e.g. how
many threads are visible above the adjusting ring.
– One rotation of the adjusting ring
1 changes the spring pretension by
approximately 1,75 mm (0,07 in).
Loosen the locking ring
2 with the hook spanner from the tool set. Change
the spring preload with the adjusting ring
1 and re-tighten the locking ring.
BASIC SETTING – SPRING PRELOAD:
WP 0118X730................. A = 22 mm
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 function.
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.

CAUTION
!
N
OT REPLACING THE RUBBER RING IN TIME CAN RESULT IN DAMAGE TO THE REAR SHOCK
ABSORBER
.
ƽ
WARNING
ƽ
THE DAMPING UNIT OF THE SHOCK ABSORBER IS FILLED WITH HIGH COMPRESSED
NITROGEN
. NEVER TRY TO TAKE THE SHOCK ABSORBER APART OR TO DO ANY
MAINTENANCE WORK YOURSELF
. SEVERE INJURIES COULD BE THE RESULT.
Lubricate rear suspension linkage
The bearings in the link lever must be greased in regular intervals. For this
purpose, a lubricating nipple
3 is mounted on the link lever.
!
CAUTION
!

FTER EACH TIME THE MOTORCYCLE IS WASHED, IT IS ESPECIALY IMPORTANT TO GREASE
THE LUBRICATING NIPPLE TO PUSH ANY WATER OUT OF THE BEARINGS
.
Checking chain tension
To check, place the motorcycle on the side stand.
Switch transmission to neutral.
Push the chain upwards appr. 30 mm (1,2 in) from the end of the chain
sliding component until the upper part of the chain is tensioned (see
illustration)
Now, the distance
B between chain and swingarm should be 0 mm. The
upper part of the chain
C must be tight (see illustration).
Correct chain tension, if necessary!

–I
F CHAIN TENSION IS TOO HIGH, PARTS WITHIN THE SECONDARY TRANSMISSION
(CHAIN, SPROCKETS, DRIVE ASSEMBLY AND REAR WHEEL BEARINGS) WILL BE
SUBJECTED TO UNNECESSARY STRESS
, RESULTING IN PREMATURE WEAR AND EVEN
CHAIN BREAKAGE
.
–T
OO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE CHAIN
JUMPING OFF THE SPROCKETS
. IF THIS HAPPENS, THE CHAIN COULD ALSO BLOCK THE
REAR WHEEL OR DAMAGE THE ENGINE
