1980 Honda CB650 · Swingarm Pivot Lock Hardware Buying guide
The package contains one nut and one lock washer. Their references identify the locking hardware, so compare them with the parts removed from the motorcycle rather than choosing from the category name alone.
One lock nut and one lock washer are supplied. Compare the old hardware and its mounting location with the references before purchase, particularly if the swingarm has been replaced. The product does not establish the condition of the pivot or its supporting components.
If the pivot has damage or wear beyond the locking pieces, establish those replacement requirements separately. Use the appropriate parts diagram and service procedure to identify the assembly. A nut-and-washer order should follow that assessment rather than stand in for it.
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.
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.
Inspect the pivot and mating components using the service information. Match the nut and washer references and establish whether additional wear or damage requires a broader repair before ordering the pair.
