1981 Honda CB650C Custom Swingarm Pivot Hardware

The swingarm service selection for the 1981 CB650C centers on a lock nut and lock washer set. Identify those pieces at the pivot before ordering. Inspect the remaining assembly so a small locking-hardware purchase is based on the actual repair rather than an assumed complete rebuild kit.

1981 Honda CB650C Custom · Swingarm Pivot Hardware Buying guide

Match both locking pieces to the existing swingarm pivot

One lock nut and one lock washer are supplied. Their references are 90354-425-830 and 90600-425-830. Use those identities with the actual pivot arrangement, particularly when a different swingarm has been installed.

Order for the locking parts actually needed

The package contains one nut and one lock washer. Match their references and condition to the original pivot hardware. If the bolt or other pivot components need attention, determine those requirements separately rather than expecting them in this two-piece order.

Preserve the correct pivot setup

A different swingarm can alter the necessary hardware even on the same frame. Compare the installed assembly and use the relevant service information for fitting and final checks. The part listing establishes package identity, not the adjustment or tightening specification.

Swingarm Pivot Hardware questions

Will a new locknut and washer cure swingarm side play?

Do not assume the visible fasteners are the cause. The product guidance calls for inspecting the pivot bolt, bushings or bearings, seals and frame bores, then setting pivot clearance by the Honda procedure. The package supplies only the locking nut and washer, not those other pivot components.

Can the lock washer be replaced by a similar-looking flat washer?

The set specifies a lock washer for reference 90600-425-830, paired with nut 90354-425-830. Preserve the prescribed locking arrangement and washer orientation, then follow the Honda tightening procedure and check smooth movement without side play. Appearance alone does not establish a substitute.

Will the set suit a different swingarm?

Check the installed pivot hardware and the conversion’s requirements first. The listed 1981 Custom application cannot establish compatibility with every substituted swingarm.
