MAINTENANCE WORK ON CHASSIS AND ENGINE »
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.
– 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 measurement 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.
