1983 Honda CB1100F · Master Cylinder Parts Buying guide

Front and rear master cylinders

The front and rear kits replace different OEM numbers, and the diaphragm listings note which master cylinder each suits. Work out which unit you are servicing first.

Which diaphragm you need

The diaphragm replacing 45520-MA5-671 is for front reservoirs on the later DOHC range. The one replacing 45520-300-000 says it fits rear master cylinders on certain CB900, CB1000 and CB1100F models. Check which reservoir you are opening before ordering.

About the Magura unit

The Magura master cylinder is a universal 16mm unit recommended for dual-disc systems. Its listing says there is no mirror mount, and that the switch, banjo bolt and washer are separate purchases. It carries no CB1100F fitment line, so treat it as a custom choice.

Master cylinder questions

Is the chrome cover a two-screw type?

Yes. The chrome cover is listed as a two-screw type replacing 45513-MA5-671 and 45513-413-941. Check that your reservoir uses a two-screw cover, not a round thread-on cap, before ordering.

Does the round cap include a diaphragm?

Yes. The round thread-on cap replacing 43513-MJ6-006 comes with a diaphragm replacing 45520-300-000. A separate reproduction cap replacing 45513-341-771 comes with a plastic O-ring instead.

Why is a brake light spring here?

The spring replacing 35357-KE4-730 carries this category tag too. Its listing says it attaches to the stop light switch at the rear, not to the master cylinder itself.
