1984 Honda CB450SC Nighthawk Fork Seal Dimensions and Both-Leg Package

The fork-seal choice for the 1984 Honda CB450SC Nighthawk is a two-seal package identified by its full 33 x 46 x 11 mm size. Its written application covers the original CB450SC forks. If replacement fork legs were fitted during earlier work, identify their own seal requirements before relying on the motorcycle year.

1984 Honda CB450SC Nighthawk · Original Fork Seal Sizing Buying guide

Use the complete seal size to confirm the fitted fork

The package contains two seals, enough for both legs on one compatible motorcycle. The manufacturer description identifies a Japanese OEM supplier and lists the CB450SC for 1982–85. It does not publish an original Honda seal reference, an alternative profile or an oil specification.

Parts to consider

Honda CB450 / CB400 / CB360 Fork Seals Two seals in the specified 33 mm applicationJapanese OEM-supplier seals measuring 33 x 46 x 11 mm, supplied as a two-piece set.View part

Do not reduce the seal choice to a single diameter

All three published measurements identify this seal. A seal described only by a 33 mm dimension has not yet been matched to the complete 33 x 46 x 11 mm specification. Resolve the full size and application before substituting a different seal or profile.

Identify a changed fork on its own application

The written coverage supports the original CB450SC fork application, including 1984. It does not establish the requirements of transplanted fork legs. Keep the replacement fork identity with the service order and confirm its seal specification before using the original motorcycle model as the deciding reference.

Common questions

How many packages should I order when both original fork legs need seals?

One package supplies two seals and is listed as enough for both fork legs on one compatible motorcycle. Confirm that both legs use the stated 33 x 46 x 11 mm specification before treating that package as the complete seal quantity.

What should I verify when the motorcycle has replacement fork legs?

Identify the installed fork application and check all three seal dimensions. The published 33 x 46 x 11 mm set covers the stated original CB450SC application; it does not establish compatibility with donor forks from the motorcycle model alone.

Can I match an earlier seal order using an original Honda number alone?

No original Honda seal number is published in this listing. It identifies the application, 33 x 46 x 11 mm dimensions and Japanese OEM-supplier origin. If an earlier order gives only a Honda number, confirm the cross-reference before selecting this set.
