Honda CR125Rw 1999 Parts Catalog – Factory Exploded Views & OEM Part Numbers

You pull the carb off a 1999 Honda CR125Rw, and you need the gasket kit. You flip through an aftermarket parts book – numbers don’t match, the picture looks like a generic Keihin. Three wrong orders later, you’re out shipping costs and the bike is still apart. That’s exactly why this factory Parts Catalog exists. Honda printed this for their dealers – 93 pages, done in August 1999, covering every bolt, seal, and cable on the CR125Rw in X trim. No guesses, no third-party reinterpretations. Just the raw OEM part numbers and exploded views straight from the assembly line.

Engine Group Breakdown: Cylinder Through Carburetor (M-1 to M-13)

The engine section starts on the engine group index (page 14 in the PDF) and walks you through every subassembly. M-1 covers the cylinder and head – you get the exact part numbers for the head gasket, cylinder gasket, dowel pins, and stud bolts. M-2 dives into the valve train: valves, springs, keepers, and the valve guide. If you’re rebuilding the top end, you’ll need the M-8 section (crankshaft and piston) – it shows the piston pin, rings, and bearing. M-12 and M-13 are the carburetor pages – both the standard Keihin and optional jetting parts. The EOP-1 gasket set page bundles the major gaskets into one number. When you see a part number in the exploded diagram, you cross-check it against the number index at the back. That kills the guesswork.

Chassis Group: 25 Sections from Levers to Labels (C-1 to C-25)

The chassis group starts after the engine section and runs 25 subsections. C-1 covers levers, cables, and switches – includes the clutch cable and throttle cable part numbers separately. C-2 and C-3 both address the front brake master cylinder (one page might be for different market variants – this catalog covers Canada VIN format and 1996+ VIN format separately). C-6 is the fork section – you get the outer tube, inner tube, bushings, and dust seal numbers. Rear brake components are C-9 (caliper) and C-10 (master cylinder). C-18 gets the drive chain – the exact 520 chain part number and clip link. C-19 shows the rear shock, C-21 the radiator. And C-23 is the tool kit – all the factory tool part numbers. If you need to replace a missing tool, you grab it from that page.

3 Indexing Methods: Illustrated, Part Number, and Name

You don’t have to flip through the whole book blind. The catalog gives you three ways in. First, the illustrated index at the front (pages 14 and 16) – you see a small thumbnail of the engine and chassis groups, then a page reference. Second, the part number index starting around page 80 – all part numbers in numeric order, mapped to the page where they appear. Third, the name index (page 84) – alphabetical Portuguese names like “embreagem” (clutch) or “embreagem” actually clutch is M-5; you find the page. The name index is especially useful if you have a part in hand but no number. All three indexes work together. Use the one that fits your current piece of paper.

Read This Before You Order: Serial Numbers and VIN Decoding

The manual opens with a section on how to locate the engine and frame serial numbers – page 5 shows you exactly where to look on the CR125Rw. It also breaks down the VIN composition for Canada and 1996+ models. That matters because Honda ran running changes mid-year. A 1999 CR125Rw with frame number above a certain cut-off might use a different swingarm or brake hose. The catalog lists the applicable VIN ranges for each model code. Ignore that, and you order a part that doesn’t line up. I’ve seen guys bolt on the wrong carburetor because they didn’t check the VIN suffix. That’s a wasted weekend.

What About the Labor Time (T.M.O.) Section?

This parts catalog includes a section on standard labor time (T.M.O. – Tempo de Mão-de-Obra) that starts on page 12. It explains how Honda computes repair time for warranty and flat-rate work. Not every parts catalog has this. If you’re billing time on a build, you can reference the T.M.O. rates for engine and chassis operations. It gives you a baseline. But keep in mind – this isn’t a service manual. There are no torque specs or step-by-step assembly instructions here. What it does give you is the exact part numbers and the exploded layout so you can order the right stuff before you start the job.

Factory parts catalogs are hard to find for this vintage. The aftermarket compilations often renumber parts or skip supersessions. This 1999 PDF is a direct scan of the original Moto Honda da Amazônia print. It covers the CR125Rw in X trim (the model code at the bottom of each page). 93 pages, full exploded views, and the three indexes. Combine it with a factory service manual for the torque specs and procedures, and you have a solid pair of documents for a full rebuild. and check the if you need other years. For general reference on 2-stroke components, see Automotive Industry Overview”> or this Automotive Battery”> page – not directly related, but shows how OEM data matters across vehicle types. Access the Factory Manual now and get the exact parts the first time.

Can I use this catalog to find torque specs for the cylinder head?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views only. You need the 1999 Honda CR125Rw service manual for torque values and procedures.

The manual is in Portuguese. Will the part numbers still work for my US bike?

Yes. Part numbers are global Honda numbers. The catalog covers Canada and 1996+ VIN formats, but the numbers cross to US models if you verify the frame/engine serial range. Use the VIN decoding section on page 7 to match your bike.
