1971 Honda CB500K · Master Cylinder Parts Buying guide
Internal service parts, reservoir diaphragm and cap are distinct items. A complete assembly is a different purchase again, and the listed 14mm, 5/8-inch and universal options should not be treated as mechanically identical choices.

A rebuild kit is intended for a compatible master cylinder; it is not a new housing or lever assembly. Check the installed unit and its condition before selecting internal parts. The assembly listings provide alternatives, but their piston sizes must be compared with the system being retained.
The diaphragm, cap and cap O-ring are separate types of reservoir component. The selected reproduction cap explicitly includes a plastic O-ring. That inclusion does not establish that a diaphragm or internal rebuild kit comes with it, so check each item against the parts already on the motorcycle.
The rebuild kit references 45530-377-305 for a compatible existing front cylinder. The separate assembly specifies a 14 mm piston. Identify the installed cylinder and piston size first; broad model fitment does not confirm an altered hydraulic setup.
The cap references 45513-341-771 and includes its plastic O-ring. The rubber diaphragm is a separate item under 45520-300-000. Compare those references and the installed reservoir, particularly if a previous owner replaced the master-cylinder assembly.
It specifies the replacement assembly’s piston size, while its stock-size wording is qualified across several models. The source asks buyers to confirm the original size. Match the fitted cylinder and brake system instead of assuming every 1971 CB500K retains matching equipment.
