– Shift into neutral, pull the lower chain section with the specified weight.
Specification
Weight of chain wear measurement 15kg (33lb.)
– Measure the distance of 18 chain links in the lower chain section.
Info
Chain wear is not always even, so you should repeat this measurement at differ-
ent chain positions.
Maximum distance at the longest
chain section
272mm (10.71in)
» If the distance is greater than the specified measurement:
– Have the chain changed.
Info
When the chain is replaced, the rear sprocket and engine sprocket
should also be changed.
New chains wear out faster on old, worn sprockets.
For safety reasons, the chain has no chain joint. Always have the chain
changed in an authorized KTM workshop, where the necessary tool is
available.
