Honda CB400 SUPER FOUR, CB400 SUPER FOUR VersionR, CB400FOURIII, CB400FOURIIIR-a, CB400FOURIIIR-b 1995 Parts Catalog

If you have spent a Saturday afternoon staring at an aftermarket parts diagram that doesn’t match your bike, you know the pain. Wrong part numbers, missing color codes, and vague references waste time and money. This is a factory Honda parts catalog – not a generic cross-reference. It covers the 1995 Honda CB400 SUPER FOUR, CB400 SUPER FOUR VersionR, CB400FOURIII, CB400FOURIIIR-a, and CB400FOURIIIR-b. 135 pages of actual part numbers from the manufacturer. No guessing which bracket fits which model year.

Engine and Frame Breakdown (Page 1)

The catalog opens with engine and frame sections. Page 1 lists every assembly for the NC31-100, NC31-120, NC31-130, and NC31-135 frame numbers. You get the exact part number for pistons, rings, gaskets, and oil seals. I have rebuilt a dozen of these engines, and the difference between an OEM piston pin and a generic one shows up after a few thousand miles. This catalog tells you which pin goes with which crank.

Color Photo and Label Guide (Page 3)

Paint codes are a nightmare on these bikes. Page 3 gives you the color photo numbers and the correct Honda paint codes – NH-237P Pure Black, Y-124P Pearl Shining Yellow, R-157 Italian Red, NH-1 Black, NH-330M Royal Silver Metallic. The table shows which color label (code ZA, ZB, ZC) corresponds to each part. Order the side cowl for a CB400FOURIIIR-a? You need the frame number to pick the right code. This page keeps you from ordering a silver part when your bike is black.

Part Number Index Accelerates The Search

Three indexes are built into this catalog: part number index, part name index, and a color photo index. When you find a bolt with a worn head, look up the part name index, get the base number, and confirm the finish code. The index is organized in Japanese, but the part numbers are universal. No translation required. I have used these indexes to source a single vibration damper mount for a Super Four – something the aftermarket catalogs simply drop from their listings.

Why A Factory Parts Catalog Beats Aftermarket Cross-References

Aftermarket catalogs merge model years, drop superseded parts, and omit color-specific hardware. This is a 1995 Honda publication – the same document dealership parts counters used. Every part number is traceable to the original microfiche. The manual shows which parts were used from frame number NC31-1000001 to 1034643. That level of granularity saves you from buying a brake lever that doesn’t clear the master cylinder.

Torque specs? This is a parts catalog, not a service manual. You still need a factory service manual for assembly torques. But when you need the correct bolt grade and length, this catalog gives you the OEM part number. Pair it with the Honda VFR750F 1994 Parts Catalog – OEM Factory Parts Breakdown for similar accuracy on another line. For a parallel build, the Honda VFR400R VFR400Z 1989 Parts Catalog – OEM Factory Manual follows the same Honda indexing system. And if you are doing a scooter restoration, the Honda PCX150, WW150EX 2014 Parts Catalog – OEM Factory Manual has that same factory DNA.

Who Should Use This Catalog

Anyone with a CB400 Super Four or FOURIII in their garage. If you are restoring a bike to original condition, the color label guide and frame number splits are critical. Beginners often skip the frame number check and end up with wrong plastic. DIYers rebuilding an engine will use the engine section to order head bolts and valve shims by factory number. Even if you read no Japanese, the exploded diagrams and numbers do the work. Store it on a tablet while you work – the pages are clean and high-contrast.

Safety note: Always verify part numbers with your local Honda dealer if the part is safety-critical (brake lines, master cylinder seals). The catalog lists the OEM part, but your dealer can confirm supersessions. Use the Automotive Industry Overview for context on how catalogs like this reduce warranty claims. And get a known-good battery – see Automotive Battery for a roundup of what I see in the shop.

Does this catalog include torque specifications?

No. This is a parts catalog. It lists part numbers, not assembly torques. You need the factory service manual for torque values.

How do I find the correct color code for my bike?

Look at the color photo section on page 3. Match your bike’s frame number range (NC31-100, -120, etc.) to the color table. Each color has a photo number and a Honda color code. Then check the color label code (ZA, ZB, ZC) for each painted part. If you see multiple codes for the same color, the label code tells you which variant your frame uses.

Will this catalog work for a 1998 CB400 Super Four?

This catalog is specifically for 1995 models. Later frames have different part numbers for many components, especially bodywork and engine covers. You need the year-specific catalog for 1998.

The pages are in Japanese – can I still use them?

Yes. Exploded diagrams and part numbers are language-independent. The part number index uses Japanese kanji for names, but the numbers are Western digits. Learn to recognize the part name index headings and you can navigate without translation.

You have a CB400 that needs a new clutch cover or a headlight bracket. A generic parts list won’t tell you which version of the bracket your frame number requires. This catalog will. Access the Factory Manual and keep it on your workbench – you will use it every time you order hardware.
