Chain maintenance
Maintenance of the X-ring chain is reduced to a minimum. Rinse off any heavy
dirt with plenty of water. Residual used grease must be removed prior to lubri-
cation (Motorex Chain Clean 611). After drying, use a chain spray specially
designed for X-ring chains (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.
Secure the screws of the chain wheel by applying Loctite and fasten them in
a crosswise order.
Tightening torque for nuts: 35 Nm
Tightening torque for screws: 50 Nm

Correct chain tension
Loosen collar nut [1], loosen lock nuts [2], and turn right and left adjusting
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.
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.
Tighten the collar nut with the required torque. A loose wheel spindle may
lead to an unstable behavior of your motorcycle.
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.
