Drive Chain
Removal, Cleaning & Replacement
Your motorcycle has an endless (riveted master
link) type chain. It should only be removed or
replaced by your Honda dealer.
When the drive chain becomes extremely dirty,
it should be cleaned prior to lubrication.
1. Clean the side surfaces of the chain with a
dry cloth.
Do not brush the rubber O-rings. Brushing
will damage them. Use of a solvent may also
damage the O-rings.
2. Inspect the drive chain for possible wear or
damage. Replace the drive chain if it has
damaged rollers, loose fitting links, or
otherwise appears unserviceable.
