1986 Honda CB450SC Parts

Parts and fitment guide for your 1986 CB450SC

This collection covers listed repair and service parts for the 1986 Honda CB450SC Nighthawk, catalogued here as CB450SCG. Match the full model-year application and installed component before ordering. The CB450 name also appears on other Honda models, so displacement alone does not establish compatibility.

Identify your CB450SC (1986)

Our catalog uses CB450SCG for this 1986 CB450SC Nighthawk application. Compare the complete frame and engine identifiers with Honda documentation for the motorcycle’s original market. Registration year, paint colour and the tank badge alone do not confirm the application.

Use our Honda CB model guide for help locating identifiers.

Use the 1986 front brake pad application

Front pad set 29-3532 specifically lists the 1986 CB450SC. The listing gives 90 × 49 × 9mm and one caliper per set. The earlier 1982–85 set is a separate product, so compare the installed caliper and removed pads rather than choosing by the Nighthawk name alone.

Fitment questions

Can I use the 1982–85 fork-seal listing for a 1986 Nighthawk? Seal set 27-1019 stops its CB450SC application at 1985. Its 33 × 46 × 11mm dimensions are product specifications, not evidence of the factory fork size on every Nighthawk. Confirm the fitted forks and the 1986 application before ordering that set.

Does oil filter 15-0007 supply all the housing seals? It explicitly lists the 1986 CB450SC, but its description specifies a paper filter element without an itemised housing-seal set. Check the seals required for the fitted housing separately before opening it for service.
