Info
When the chain is replaced, the rear sprocket and engine sprocket
should be replaced at the same time.
A new chain will wear faster on an old, worn rear sprocket or engine
sprocket.
For safety reasons, the chain has no chain joint. Always have the chain
changed in an authorized KTM workshop, where they have the necessary
special tools.
