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 lubrication (Motorex Chain
Clean 611). After drying, use a chain spray specially designed for X-ring chains (Motorex
Chainlube 622 Strong).
– 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 motor-
cycle could easily get out of control.
– The chain does not have a chain joint for safety reasons. Always have the chain replaced
in an authorized KTM workshop where the service technicans have the required riveting
tool.
– Never mount a normal chain joint.
Also check sprockets and chain guides for wear, and replace if necessary.
Checking the chain for wear
To check the chain for wear proceed as follows:
Switch the transmission to idle and put a load of approx. 15 kilograms
(33 lbs) on the lower part of the chain (see illustration). Now measure the distance between
18 chain rollers on the upper part of the chain. The chain needs to be replaced when the
distance is 272 mm (10.70 in). Since chains do not always wear evenly, repeat the meas-
urement at different parts of the chain.
Replace the chain if any X-rings are missing.
NOTE:
If you mount a new chain, the sprockets should also be replaced. New chains wear faster if
used on old used sprockets.
