1985 Honda CB450SC Nighthawk Suspension Sealing and Mounting Purchase Plan

A 1985 Honda CB450SC Nighthawk suspension order can combine original fork or hub service with a separate custom-shock proposal. Seals and cap O-rings have explicit two-piece supply; front bearings are individual purchases. Keep those counts attached to the service location and establish the mounting requirements of any shorter shock before adding it.

1985 Honda CB450SC Nighthawk · Fork, Shock and Hub Purchases Buying guide

Use the service position to separate supply counts and fit requirements

Fork oil seals measure 33 x 46 x 11 mm, and dust boots identify a separate 33 mm protective application. Two 94608-50000 O-rings service the fork caps. The front uses two individual 6302-2RS bearings. Universal 290 mm shocks require matching mount style, bushings, travel and clearance.

Keep the fork’s sealing locations separate

Oil seals, dust boots and cap O-rings are listed as different parts for different locations. Their similar two-piece supply does not establish a combined package. Confirm which areas need renewal, using each product’s application and contents before preparing the fork-service purchase.

Check the proposed shock mounts rather than the motorcycle label

The chrome custom shock specifies an upper eye and lower clevis. The black eye-to-eye alternative uses a different lower attachment and bushing size. Determine the actual mounts and required clearances before relying on their shared 290 mm length or a universal application description.

Common questions

What should be inspected when dust boots are renewed during a fork repair?

Check fork tubes, oil seals, retaining clips and seal seats, and address leakage before fitting boots. The two supplied boots protect the exposed seal area; use that inspection to decide whether the separate oil-seal package is also required.

How many cap O-ring packages cover the two compatible fork legs?

The package supplies two O-rings, one for each fork cap, replacing 94608-50000. One matched package therefore services both caps. Inspect their grooves and sealing surfaces for corrosion or damage when identifying the required cap-sealing work.

Which measurements separate the chrome clevis shocks from the black eye-to-eye option?

Chrome shocks measure 290 mm eye-to-clevis and specify 12 mm ID x 21 mm upper bushings. The black eye-to-eye pair uses 10 mm ID x 21 mm bushings at both ends. Compare actual attachments and clearances before deciding between these custom configurations.
