Honda CBR400RR, CBR400RRL, CBR400RRL-II 1991 Parts Catalog

You know the drill – you’re staring at a bin of bolts, a faded fairing, and a parts fiche that either shows the wrong year or lumps three models into one blurry drawing. That’s when you need the actual factory Honda CBR400RR, CBR400RRL, CBR400RRL-II 1991 Parts Catalog. This is the same binder the dealer’s parts counter pulled from back in ’91. 117 pages, Japanese text but part numbers are universal. No second-guessing whether that gasket fits the NC29-100 frame or the RRL-II.

Think about the time you lost hunting for a fuel petcock for a CBR400RRL – aftermarket catalogs called it a “CBR400” and crossed their fingers. This catalog breaks each model out separately, with frame serial number ranges. Page 4 gives you the table of contents: Engine group, Frame group, parts number index, parts name index. That’s how you find what you need without scrolling through a 300-page PDF of irrelevant junk.

Engine and Frame Group Breakdown

The catalog splits into two main sections: Section 1 covers the engine group – pistons, rings, valves, clutch, oil pump, the whole rotating assembly. Section 2 handles the frame group – fairing brackets, subframe, wiring harness clips, fuel tank, exhaust. Each component gets a diagram with callouts and a table listing the part number, quantity, color code if applicable, and any supersession notes. If the part carries a star mark (★), that means it was revised from the original print – pay attention to those.

Color coding is handled on page 2. Honda used photo numbers and color labels to match bodywork. Fighting Red (R-134), Granite Blue Metallic U (PB-184M-U), Passion Red (R-109) – they’re all there with the code numbers. The catalog even shows you how to cross-reference the color code to the correct decal and mark set. If you’re restoring a CBR400RRL that left the factory in that rare PB-184MU shade, this is your only reliable source.

Why OEM Parts Catalog Beats Aftermarket

Aftermarket parts catalogs – I’ve seen them. They take a generic diagram, photoshop the number, and pray the bolt fits. This Honda factory document goes through a formal revision process. The publication date is 1991, third edition. Every part number is tied to a specific frame range (NC29-1000001~). When you order a part from this catalog, you give the dealer the exact 10-digit Honda number – no interpretation, no “maybe this fits.” That’s the difference between a job that goes together in an hour and one that leaves you with a snapped fastener and an angry customer.

For the shop owner, handing this catalog to your mechanic saves arguments. “The manual says 6mm bolt, 12mm length, flange head, part 90106-MV4-000.” That’s what’s printed. No opinion required.

How the Parts Indexes Work

Page 4 and 5 outline the indexes. There are two: a part number index (numerical) and a part name index (alphabetical, Japanese). If you have the old part number but it’s been superseded, the index tells you the new number. If you know the name but not the number, the name index gets you to the right page. You don’t need to read Japanese to use the number index – it’s all digits. The diagrams are labeled with reference numbers that point straight to the table.

One bit that trips up beginners: parts listed with a quantity in parentheses are optional. Parts with usage code “N” are service-only – not necessarily on every bike from the factory. Pay attention to that when ordering because ordering an optional bracket that your bike didn’t come with means drilling holes you don’t want.

Does This Catalog Cover CBR400RR, CBR400RRL, and CBR400RRL-II Separately?

Yes. The front cover lists all three models: CBR400RR, CBR400RRL, CBR400RRL-II (NC29-100). Page 3 shows a table of frame serial numbers and color plates for each. The diagrams in the engine section are the same across the platform for most hard parts, but bodywork, decals, and some electrical pieces are model-specific. The RRL-II got different seat foam and a revised airbox – the catalog shows those differences. You won’t find that in a Haynes manual.

If you’re a DIYer building a track bike from a basket case, this catalog is the only way to confirm which year and model your donor came from. Cross the frame vin with the serial range listed, then look up the color photo number to verify the original paint code. That saves you from buying a tank that has the wrong mounting tab location.

3 Things This Catalog Won’t Do

First, it won’t walk you through disassembly – that’s what a service manual is for, like the Honda CBR400RR Service Manual”>Honda CBR400RR Service Manual that covers torque specs and procedures. Second, it won’t give you wiring diagrams. Third, it won’t tell you why a part failed – just what the factory intended to be there. If you need to understand why your CBR400RRL blew a head gasket, get the service manual. If you need to order the correct gasket, get this parts catalog.

For other Honda projects, check the Honda VFR750F 1994 Parts Catalog – OEM Factory Parts Breakdown”>Honda VFR750F 1994 Parts Catalog or the Honda VFR400R VFR400Z 1989 Parts Catalog – OEM Factory Manual”>Honda VFR400R VFR400Z 1989 Parts Catalog. Both are factory OEM documents.

Understanding the wider Automotive Industry Overview”>Automotive Industry Overview helps, but for this bike, you need the catalog. Also, remember that battery terminals are negative-first disconnect, positive-first connect – that’s basic Automotive Battery”>Automotive Battery safety.

Can I use this catalog to order parts from my local dealer?

Yes. Give them the 10-digit part number from the diagram table.

What if my bike has aftermarket bodywork – will the color codes still match?

No. Aftermarket bodywork uses different pigments and often skips the clearcoat. The color codes in this catalog are for OEM painted parts only. If you stripped the fairings and want to match the frame color, you’ll need to take a paint chip to a body shop. The catalog tells you the OEM code (e.g., PB-184M-U), but aftermarket paint suppliers may mix it slightly different. Always test a small area before committing to a full panel. Also, the decal sets listed (uppercowl decal, marks) are specific to the factory adhesive – aftermarket decals may be smaller or positioned differently. The catalog’s color photo pages are printed on glossy stock, so use them as a guide, not a color match guarantee.
