screws [3] equally far. Tighten lock nuts.
Before tightening the collar nut, verify that the chain adjusters [4] are sitting
close to the adjusting screws and that the rear wheel has been aligned with
the front wheel.
Tighten collar nut [1] to 80 Nm (60 ft.lb).

– TIGHTEN THE COLLAR NUT WITH THE REQUIRED TORQUE. A LOOSE WHEEL
NOTE:
The large adjusting range of the chain adjusters (32mm / 1.25 in) allows you
to use different secondary ratios in combination with the same chain length.

The chain adjusters [4] can be rotated by 180°.
ALWAYS MOUNT THE CHAIN TENSIONER EQUALLY ALIGNED.

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 (Motorex Chainlube 622).
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.
WHEN 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.

Chain wear

To check the chain wear, observe the following indications:
Shift the gear into idling and pull the upper chain strand with approx. 10-15
kilograms (33 lb) upwards (see figure). Now one can measure a space of 18
chain reels at the lower chain strand. The chain should be replaced at the lat-
est when a space of 272 mm (10.70 in) is measured. Chains do not always
wear off evenly, therefore repeat the measurement at different places on the
chain.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New chains
wear faster if used on old used sprockets.
WHEN YOU ASSEMBLE A REAR SPROCKET WITH 14T, THE COLLAR MUST BE ON
THE INSIDE.
SECURE THE SCREWS OF THE CHAIN WHEEL BY APPLYING LOCTITE AND FASTEN
THEM IN A CROSSWISE ORDER.

YOU HAVE THE TIGHTENING TORQUE CORRECTED BY A KTM DEALER AS SOON
AS POSSIBLE. A LOOSE AXLE MAY LEAD TO AN UNSTABLE DRIVING BEHAV-
IOR OF YOUR MOTORCYCLE.
SPINDLE MAY LEAD TO AN UNSTABLE BEHAVIOR OF YOUR MOTORCYCLE.
