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.
Chain wear
In order to check the chain wear, regard the following instructions:
Shift the gear into idling and pull the upper chain strand with approx. 10-15
kilogramm (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 (10.88 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.
