Vespa LX 125 2009 Parts Catalog – Factory OEM Part Numbers

Description

You got a Vespa LX 125 from 2009 that needs a new crankshaft. You pull up a generic parts site, type in the model, and get a list that might be close. That’s a gamble. I’ve seen too many guys order a cylinder with the wrong bore because the aftermarket catalog didn’t list the correct revision. This Vespa LX 125 2009 Parts Catalog is the OEM factory document. 65 pages, direct from Piaggio. It tells you exactly which part number goes where, with exploded diagrams and table references. No guesswork, no returns.

Engine Assembly: Table 01.02 to 01.45

The engine section is the heart of this catalog. You get tables for the crankcase (Table 01.05), the crankshaft (Table 01.06), and the cylinder-piston-wrist pin unit (Table 01.07). Each table shows an exploded view with callouts and part numbers. Need the valve assembly? Go to Table 01.10 – Head unit – Valve. The rocking levers are on Table 01.11. Every fastener, gasket, and seal is listed. If you’re rebuilding the top end, you’ll find the cylinder head cover on Table 01.12. The cooling system is covered under Table 01.15 – Crankcase cover – Crankcase cooling. That’s where you get the part numbers for the fan cover and ducting.

Crankshaft and Cylinder: Critical Part Numbers

When you’re ordering a new crankshaft, you need the exact OEM part number. The aftermarket lists often cross-reference wrong. This catalog gives you the factory number from Table 01.06. Same for the cylinder – Table 01.07 lists the piston, wrist pin, rings, and cylinder itself. I’ve seen DIYers order a 47mm piston when the 2009 LX 125 uses a 48mm. Check the catalog first. It’s also got the head gasket, valve guides, and seals. Don’t trust a third-party site that guesses.

Cooling System: Factory Diagrams for the Crankcase Cover

Table 01.15 is where you find the cooling system parts. The crankcase cover includes the cooling fan housing and ducts. The catalog shows the exploded view with part numbers for the impeller, cover gasket, and fasteners. If you’re replacing a damaged cooling duct or the fan itself, this is the only source that matches the 2009 LX 125. The frame and bodywork sections also cover the wheel housing and mudguard for the cooling air flow. Miss a part number, and you’ll be waiting for a backorder.

Why Use a Factory Parts Catalog Over Aftermarket?

Aftermarket parts catalogs are compiled from reprints or third-party data. They miss engineering revisions. The 2009 Vespa LX 125 has a specific engine prefix M681M. The factory catalog matches that. Page 2 shows the chassis and engine prefixes. The alphanumeric index on page 5 lets you look up any part by name. The catalog is organized by system: Engine, Frame, Handlebars, Suspensions, Braking, Electrical. Each table has a unique number. You can cross-reference with the service manual. For a deeper understanding of how the engine works, check out Internal Combustion Engine on Wikipedia. For the broader automotive industry context, see Automotive Industry Overview.

Who Needs This 65-Page Catalog?

If you own a 2009 Vespa LX 125, you need this. DIY mechanics doing a top-end rebuild, replacing the valve train, or ordering a new crankshaft. Home garage enthusiasts who want to keep their scooter on the road without guessing. Beginners who want to learn the part numbers while they work. The catalog doesn’t have torque specs or service procedures – that’s what the service manual is for. But without the correct part numbers, you can’t even order the right bolts. Pair this with the Vespa LX 125 LX 150 2008 Service Manual – Factory Specs for the torque values. For the 2010 model, get the Vespa LX 125 2010 Parts Catalog – OEM Factory Spare Parts. If you need the 150cc version, the Vespa LX 150 Parts Catalog – 78-Page Factory Parts Manual covers that.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual.

How do I use the alphanumeric index to find a part?

The catalog has an alphanumeric index starting on page 5. You look up the part name or reference number, then it directs you to the table number. For example, if you need the crankshaft, find ‘Crankshaft’ in the index, then go to Table 01.06 on page 13. Each table shows an exploded diagram with callouts and part numbers. Cross-reference with the part number list to order the exact OEM piece. The index is sorted by both part name and OEM number, so you can work either way.
