The brake and clutch master rebuild kits have separate replacement references, but their descriptions do not itemize every internal part. Confirm any essential component before deciding whether it needs a separate purchase.
The linked slave piston replaces 22863-MB0-003. Honda’s US-market CB650SC manual calls for checking the piston and slave-cylinder bore for surface damage and measuring both. Use those inspection results and the applicable service limits when deciding the repair.
The named contents are an oil seal, spring, piston cup and bleeder cap. A piston cup is not confirmation that a replacement piston is supplied. Confirm the package contents if the inspected repair also needs the separately listed piston.
The kit includes the pushrod and bushing, replacing references 22884-MB0-006 and 22885-MB0-006. It is identified for the clutch master cylinder; compare those parts with the worn components before adding it.
Verify the maker and model of the installed control first. The listed original-application kit does not establish internal compatibility with a replacement master cylinder.
