Honda NT650 1993 Parts Catalog – Factory Parts Breakdown for the Hawk GT

Let me tell you something about parts catalogs. If you’ve ever ordered a camshaft or a crankcase gasket for a Honda NT650 and got the wrong piece, you know the pain. This 1993 factory parts catalog is what Honda dealers used to order parts by the book. It covers the NT650 Hawk GT from 1988 through 1991 — all one generation. I’ve been a master tech for 28 years, and I still grab this when I’m rebuilding an engine or chasing a supersession chain. You don’t guess with part numbers. You look them up in the OEM grid.

Engine group work — cylinder head, camshaft, crankshaft, transmission — every single bolt and seal is listed with a Honda part number and a reference number. No aftermarket cross‑reference nonsense. This is the 102‑page printed book from American Honda Motor Co., December 1993. First edition. If you’re pulling apart the top end, you need the exploded diagrams for the cylinder head cover, camshaft holder, FR and RR cylinders, and the cam chain assembly. Page B‑1 in the catalog’s grid covers the entire engine group, and the detail goes down to the last washer.

Engine Group Coverage: Cylinder, Camshaft, Crankshaft, Transmission

Pick a component — the FR cylinder, the camshaft, the crankshaft, the transmission. They’re all here as separate subsections. The catalog breaks the engine group into 23 sub‑groups: cylinder head cover, camshaft holder, FR cylinder, RR cylinder, camshaft, cam chain, crankcase covers, clutch, starting clutch, oil pump, crankcase, crankshaft, transmission, gearshift drum, water pipe, carburetor assembly, carburetor components, air suction valve, and gasket kits. Each one has an exploded view with reference numbers that tie directly to the part number list. Need a front cylinder head gasket? The gasket kit group has it. Need the exact camshaft part number for the ’89 model? The camshaft section lists it by year and serial number range.

This isn’t a service manual — it won’t tell you how to set valve lash or torque the camshaft holder bolts. But if you’re ordering parts, you need the genuine Honda number. Aftermarket catalogs often list superseded parts wrong or miss the color code. Honda’s own catalog includes the supersession chain right in the part number field. It’s printed right there: “Several part numbers may be listed under one (1) reference number. For your convenience the current supersede chain, as of print date, has been listed for you.” That’s from page 2 of the manual. You can’t beat that for accuracy.

7 Systems Covered – From Engine to Frame to Wiring

Besides the engine group, the catalog covers the entire frame group: headlight, speedometer, switches, front brake master cylinder, handlebar, steering stem, front fork, front and rear brake calipers, wheels, fuel tank, seat, battery, air cleaner, exhaust, pedals, stand, swingarm, shock absorber, turn signals, tail light, wire harness, radiator, frame, tools, decals, and even the cannister. That’s 30‑plus sub‑groups in the frame section alone. The wire harness section is especially helpful if you’re tracing a broken wire or need the correct connector housing. The part number index and description index at the back let you find anything alphabetically or by number.

For the battery and charging system, refer to the battery sub‑group. If you’re rebuilding the front master cylinder, the FR brake master cylinder section gives you the piston kit and reservoir cap part numbers. This catalog runs from the VIN construction page (how to decode the NT650 VIN) all the way through color tables, model ID photos, and a list of commonly required replacement parts like oil filters, spark plugs, and brake pads. The “Commonly Required Replacement Parts” section on grid page A‑9 is a fast reference for consumables.

Who Should Buy This Manual

If you own an NT650 Hawk GT — the ’88, ’89, ’90, or ’91 – and you do your own wrenching, you need this on your hard drive. Same if you’re a shop that sees these bikes come in every few years. Chasing a part number from an online forum post might get you close, but it won’t give you the supersession chain or the correct color code. DIY guys who’ve ordered the wrong clutch cover gasket twice — I’m talking to you. This catalog stops that waste. Even if you’ve got a factory service manual, the service manual often lists part numbers that have been superseded or are incomplete. The parts catalog is the final word.

For the serious home mechanic: you can also pair this catalog with other Honda factory docs. Check out the Honda VFR750F 1994 Parts Catalog – OEM Factory Parts Breakdown if you have a VFR. Or the Honda VFR400R VFR400Z 1989 Parts Catalog – OEM Factory Manual for the 400‑class bikes. For scooter work, the Honda PCX150, WW150EX 2014 Parts Catalog – OEM Factory Manual covers later models.

Source Validity – OEM Factory Print vs Aftermarket Copies

I’ve seen aftermarket “parts manuals” that re‑label the drawings and swap the part numbers with generic equivalents. They’re useless. This PDF is a direct scan of the official Honda Parts Catalog, printed in December 1993 by American Honda Motor Co. It includes the original copyright notice and the grid system that Honda dealers used on microfiche. The file itself is a clean PDF with bookmarks for every section — engine group, frame group, index — so you can jump straight to the camshaft or crankshaft page without scrolling. No third‑party garbage. No missing pages. This is the real thing.

If you want background on how the automotive parts industry works, the Automotive Industry Overview has context on OEM documentation standards. For battery specs, check the Automotive Battery guide for cross‑referencing.

FAQ – Parts Catalog vs Service Manual

Q: Is this the same as a service manual?

A: No. This is a parts catalog. It lists every OEM part number and diagram, but it doesn’t tell you how to remove the cylinder head or torque the camshaft holder.

Q: Why would I need a parts catalog if I already have a service manual?

A: Service manuals often print part numbers as of the publication date, but those numbers get superseded within a few years. Honda dealers use the parts catalog to look up the current supersession chain — that chain is printed right in the part number column. The catalog also shows you every variation by year and serial number (e.g., ’89 vs ’90 camshaft), which a service manual lumps together. If you’re ordering a crankshaft or a transmission bearing, you need the supersession data. Plus the exploded diagrams in the parts catalog are separated by sub-group, so you see exactly where each clip and washer goes. It saves you from ordering five gaskets to find the right one.
