Identify your CB750K (1981)

Record the complete frame or VIN marking and the engine stamping before ordering model-specific parts. Match them to Honda documentation for the motorcycle’s original market.

• Frame / VIN — copy every stamped character, including the prefix.
• Engine number — record the complete marking separately from the frame number.

A chart abbreviation is not a complete VIN. Keep a clear photograph of the frame marking and identification plate so every character can be checked.

Use the linked chart as a model reference alongside original-market records. Its starting entry alone does not establish a production cutoff or build date.

Check the two boot patterns and filter hardware

Airbox boot set 02-6555 contains four boots: two replacements for 17253-425-000 and two for 17254-425-000. Keep those two patterns in mind when comparing the removed boots. Clamps are separate; the listing specifies four 58–60mm band clamps 15-0690 or four gear clamps 15-0670. Oil filter 15-0002 is the paper element; replacement O-rings, springs and washers are offered separately.
