Drive Chain

(Refer to the Safety Precautions on page 43.
The service life of the drive chain is dependent upon
proper lubrication and adjustment. Poor maintenance
can cause premature wear or damage to the drive
chain and sprockets.
The drive chain should be checked and lubricated as
part of the Pre-ride Inspection (page 36). Under severe
usage, or when the motorcycle is ridden in unusually
dusty or muddy areas, more frequent maintenance will
be necessary.
