About the Honda CX500

Find the right CX500 parts by model, fuel system and repair.

Honda Motorcycle Logo

Honda introduced the CX500 for 1978, pairing a liquid-cooled V-twin with shaft final drive. The Custom and Deluxe joined the North American range for 1979. Their revised tanks, seats, controls and wheels gave owners different versions of the same basic engine concept.

The 1982 CX500 Turbo added electronic fuel injection and a turbocharger. Treat its fuel, brake and chassis equipment as a separate application when planning repairs. A part that fits a carbureted CX500 does not automatically fit the Turbo.

Which CX500 parts are shared across models?

Some cover gaskets list the Standard, Custom, Deluxe and Turbo, while the featured clutch plates split Turbo from non-Turbo applications. Brake and carburetor coverage has its own year boundaries. Use the examples below to compare the part you need, not just the CX500 engine size.

Know your CX500 before choosing partsStandard, Custom, Deluxe and Turbo: what changes?

CX500 Standard

CX500 Standard applications

Use the CX500 entry for the Standard. Parts labelled for CX500C or CX500D need their own application check.

Parts checkpoint: Record the year and market before comparing forks or brakes.

CX500C Custom

CX500C Custom parts

The Custom used pull-back handlebars and a teardrop tank. Changes to bars or controls make cable routing and reach especially relevant.

Parts checkpoint: C-model engine coverage does not establish cable or chassis interchange.

CX500D Deluxe

CX500D Deluxe parts

The Deluxe arrived with a stepped seat and a 16-inch rear wheel in the North American 1979 range. Keep the D suffix in your search.

Parts checkpoint: Choose rear shoes, front pads and clutch plates by their separate fitment lines.

1982 Turbo

1982 Turbo parts under two catalog labels

The CX500TC Turbo range includes the clutch and cover-gasket examples. The CX500T Turbo range includes the rear-brake and mechanical-seal examples.

Parts checkpoint: These are two catalog selections for the 1982 Turbo, not evidence of complete parts interchange.

Identify your motorcycle before orderingCX500 frame, engine and model checklist

Record the motorcycle’s markings and original model information before choosing parts, especially after an engine or chassis conversion.

  • Confirm the full model on the motorcycle and its original paperwork. Use the model year, which may differ from its first registration date.
  • Record both frame/VIN and engine markings. A replacement engine can change the parts needed without changing the frame identity.
  • Identify the fuel system: carbureted Standard/Custom/Deluxe or fuel-injected Turbo.
  • For chassis repairs, photograph the caliper, master cylinder or fork markings. Check dimensions on a changed or imported assembly.

Contact PartsNMore with the model year, frame and engine markings and photos of the part being repaired.

Honda CX500 parts questions

What is the difference between CX500, CX500C and CX500D parts?
CX500 identifies the Standard, CX500C the Custom and CX500D the Deluxe in this catalog. Some service gaskets share applications, but carburetors, controls, forks and brakes must be matched separately. For example, the featured carburetor kit lists Custom 1980–1982 and Deluxe 1980–1981; it does not establish every CX500 year.
Are CX500T and CX500TC both 1982 Turbo parts?
Honda’s 1982 500 Turbo is identified as CX500TC in the factory parts catalog. PartsNMore also records products under CX500T. Use the TC page for featured clutch and cover-gasket parts, and the T page for featured rear-brake and water-pump seal parts. Both selections still require an individual product fitment check.
Which carburetor rebuild kit fits my Honda CX500?
Match the full model, year and carburetor identification. The featured Custom/Deluxe kit covers CX500C 1980–1982 and CX500D 1980–1981. That does not confirm a Standard or 1979 application. The 1982 Turbo uses fuel injection and does not use these carburetor kits.
Can I use the same clutch plates on a CX500 and CX500 Turbo?
The featured non-Turbo steel plate lists CX500 1978–1979, CX500C 1979–1982 and CX500D 1979–1981. A different steel plate is listed for CX500TC 1982. Match the fitted clutch and plate position. The plates are sold individually, so order the quantity required.
