Pivot bearing
The pivot bearing 1 for PDS suspension struts at the swinging fork is
Teflon-coated and must not be lubricated with either grease or other lubri-
cants. Grease and other lubricants cause the Teflon coat to dissolve, whe-
reby the bearing’s lifecycle will be reduced dramatically.
When cleaning your bike with a high-pressure cleaner, do not aim the high-
pressure spray directly at the pivot bearing.
Check chain tension
To check the chain tension, park the motorcycle.
Press chain upward at the end of the chain sliding component. The
distance between chain and swing arm should be approx. 15 mm (0.6 in).
In the course of this procedure, the upper chain portion A must be taut
(see drawing).
If necessary, correct chain tension.
WARNING
–IF CHAIN TENSION IS TOO GREAT, PARTS WITHIN THE SECONDARY TRANSMISSION
(CHAIN, CHAIN WHEELS AND REAR WHEEL BEARINGS) WILL BE SUBJECTED TO UNNE-
CESSARY 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 CHAIN WHEELS
. IF THIS HAPPENS, THE CHAIN COULD ALSO BLOCK
THE REAR WHEEL OR DAMAGE THE ENGINE
.
–I
N EITHER CASE THE OPERATOR IS LIKELY TO LOSE CONTROL OF THE MOTORCYCLE.
Correct chain tension
Loosen collar nut 2, loosen lock nuts 3, and turn right and left adju-
sting screws
4 equally far. Tighten lock nuts.
Before tightening the collar nut, verify that the chain adjusters
5 are sit-
ting close to the adjusting screws and that the rear wheel has been aligned
with the front wheel.
Tighten collar nut
2 to 80 Nm (60 ft.lb).
WARNING
–IF YOU DONT 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
.
–T
IGHTEN THE COLLAR NUT WITH THE REQUIRED TORQUE. A LOOSE WHEEL SPINDLE
MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE
.
Chain maintenance
For long chain life, good maintenance is very important. Chains with-
out O-rings should be cleaned in fireproof solvent regularly and after-
wards treated with hot grease or chain spray (Shell Advance Bio
Chain).
O-ring chains on the other hand are very simple to clean. The best
way is to use lots of water, but never use brushes or cleaning liquids.
After letting the chain dry, you can use a special O-ring chain spray
(Shell Advance Bio Chain).
