Ducati 620 S 2002 Parts Catalog – Factory OEM Spare Parts List

Been burned by a parts catalog that gave you the wrong fork seal or a clutch plate that doesn’t fit? I have. That’s why I only pull parts numbers from the factory source. The Ducati 620 S 2002 Parts Catalog is the original document Ducati sent to dealers – 158 pages of exploded diagrams, part codes, and the specific rules for ordering. No reprints, no generic aftermarket compilations. If you’re rebuilding a 620 S or sourcing parts for a customer’s bike, this is the only list you should touch.

What This Parts Catalog Actually Covers

This catalog splits the 620 S into 38 numbered sections. Starts with tooling (001 Attrezzi Speciali) then goes through every major assembly: cambio (transmission), frizione (clutch), cilindri e pistoni (cylinders and pistons), distribuzione (timing), telaio (frame), freni (brakes), impianto elettrico (electrical system), and carenatura (fairing). Each section has its own page range – 158 total. Need the exact piston code? That’s section 007. Need to order the correct sprocket for the final drive? Section 031 – forcellone posteriore e catena. The catalog indexes everything by Italian section titles, but the part numbers and diagrams work in any language. English, French, German – the part codes are the same.

Ordering the Right Part: The Serial Number Rule

Flip to page 1 of the original document. The first thing Ducati tells you, in four languages, is to include the motorcycle’s serial number (stamped on the steering head) when you order. That’s because some parts changed mid-year or between markets. The catalog lists validity markers – f.m. (fino alla matricola) and d.m. (dalla matricola) – so you know if your frame number falls before or after a production split. If you skip that step, you’re gambling on fitment. I’ve seen guys order a vertical cylinder head only to find the valve guide size changed at engine number 123456. This catalog lets you check before you buy.

38 Sections – From Attrezzi to Carenatura

Every numbered section covers a specific grouping. 003 Cambio, 006 Imbiellaggio (connecting rods), 013 Testa Distribuzione, 028 Impianto Elettrico – 38 in total. That doesn’t include the tool lists and diagnostic tester pages at the front (001a, 001b, 001c). The wiring diagrams are in section 022 (Fanale e Cablaggio Elettrico) and 028. For example, section 029 is the battery support, section 036 is the fuel system, section 037 the tank, section 039 the full fairing, and 039a the half fairing. If you’re replacing a damaged side panel, you need to know which sub-section applies. This catalog has it broken out.

Why You Avoid Aftermarket Parts Catalogs

Aftermarket catalogs guess. They take a 620 S listing and apply it across model years or ignore the difference between the 620 S and the 620 SS or Monster 620. The factory catalog, on the other hand, was printed specifically for the 2002 620 S (i.e. – injection model). The OCR excerpt on page 1 explicitly says: “The contents of this catalogue are general and can undergo changes without prior notice.” That’s a disclaimer, not a flaw – it means Ducati updated parts through the production run. The catalog includes those updates. Aftermarket ones don’t. I’ve seen aftermarket listings sell you a 620 Monza part for a 620 S and call it interchangeable. It’s not. Stick with the OEM source.

Verify the Part Number Before You Click

The diagrams in this catalog are schematic, not exact representations – Ducati says that on page 1. So don’t match shapes. Match the part code. Each drawing has a number balloon pointing to a code. Look up that code in the parts list next to the drawing. That code is the official Ducati part number. Use it when ordering from any dealer or online. If the number matches the diagram, you’re good. If it doesn’t, you’ve got the wrong section. Check the serial number validity range next to the code. If your VIN falls between f.m. and d.m., you’re clear. Do all that and you’ll get the right part the first time.

Does this catalog include torque specs for assembly?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views only. For torque values, bleed procedures, and disassembly steps, you need the corresponding factory service manual.

How do I know if a part is compatible with my 2002 Ducati 620 S?

Cross-check the part code from this catalog against the serial number validity range printed beside each entry. The catalog marks parts as valid “fino alla matricola” (up to VIN) or “dalla matricola” (from VIN). If your bike’s frame number falls within the range, the part fits. The catalog also lists market-specific variations (GB, D, CH, J, AUS, SGP, F, E) – if your bike was sold in Germany, for example, look for the D flag. That level of detail is why this is the only catalog you should trust for a correct order.

Access the Factory Manual and keep a digital copy in your shop tablet. When you’re on the phone with a parts counter or scrolling through a supplier site, you’ll have the exact code in front of you. No second-guessing. No returns because the catalog said a 620 S fork was the same as a 620 SS. Do it right the first time.
