Drive Chain - Honda CRF250F 2020 Owner's Manual

Drive Chain

Refer to Safety Precautions on page 39.
The service life of the chain depends on proper
lubrication and adjustment. Poor maintenance
can cause premature wear or damage to the
drive chain or sprockets.
Under severe usage, or when the motorcycle is
ridden in unusually dusty or muddy areas, more
frequent maintenance will be necessary.
Before servicing your drive chain, turn the
engine OFF, lower the side stand, and check
that your transmission is in neutral.
It is not necessary to remove or replace the
drive chain to perform the recommended
service in the Maintenance Schedule.
