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.
!
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
. S
EVERE INJURIES COULD BE THE RESULT.
Checking chain tension
Support the motorcycle on the center stand or side stand, respectively.
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
A between chain and swingarm should be 0 mm. The
upper part of the chain
B must be tight (see illustration).
Correct chain tension, if necessary!
ƽ
WARNING
ƽ
–IF CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY POWER TRANS-
MISSION (CHAIN, CHAIN SPROCKETS, TRANSMISSION AND REAR WHEEL BEARINGS)
WILL BE SUBJECTED TO UNNECESSARY STRESS
, RESULTING IN PREMATURE WEAR AND
EVEN CHAIN BREAKAGE
.
–TOO MUCH SLACK IN THE CHAIN, ON THE OTHER HAND, CAN RESULT IN THE CHAIN
JUMPING OFF THE CHAIN WHEELS
. IF THIS HAPPENS
, THE CHAIN COULD ALSO BLOCK
THE REAR WHEEL OR DAMAGE THE ENGINE
.
–IN EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTORCYCLE.
Correct chain tension
Loosen collar nut

WARNING
ƽ
IF YOU DON’T HAPPEN TO HAVE A TORQUE WRENCH AT HAND, MAKE SURE YOU HAVE
THE TIGHTENING TORQUE CORRECTED BY A
KTM DEALER AS SOON AS POSSIBLE. A
LOOSE AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAVIOR OF YOUR MOTORCYCLE
.
Chain maintenance
For long chain life, good maintenance is very important. X-ring chains
require only modest maintenance. The best way is to use lots of water, but
never use brushes or solvents. After letting the chain dry, you can use a
special X-ring chain spray (Shell Advance Bio Chain).
ƽ
WARNING
ƽ
NO LUBRICATION IS ALLOWED TO REACH THE REAR TIRE OR THE BRAKE DISK, EITHERWISE
THE ROAD ADHERENCE AND THE REAR WHEEL BRAKING EFFECTS WOULD BE STRONGLY
REDUCED AND THE MOTORCYCLE COULD EASILY GET OUT OF CONTROL
.
!
CAUTION
!
W
HEN MOUNTING THE CHAIN JOINT, THE CLOSED SIDE OF THE SAFETY DEVICE MUST
POINT IN RUNNING DIRECTION
.
Also check sprockets and chain guides for wear, and replace if necessary.
