BMW R1200 GS Parts Catalog – Factory Exploded Diagrams & Part Numbers

You’ve got a BMW R1200 GS Parts Catalog in your hands – 142 pages of factory diagrams that show every nut, bolt, gasket, and seal BMW put into the K25 series. Not a service manual. Not a repair guide. This is the parts book dealership parts counter uses. I’ve seen too many guys order a “short engine” from an aftermarket site and end up with a long block missing the alternator bracket. Stop guessing part numbers. This catalog gives you the exact OEM part number for every component, from the engine housing (11 11 7 668 226) to the breather pipe (11 15 7 674 098).

If you’re rebuilding a crashed GS or sourcing parts for a full engine swap, this PDF saves you the trip to the dealer. You look at the exploded view, find the part number, and cross-reference it against real inventory. No more decoding blurry online photos. The diagrams are crisp – page 1 shows the ENGINE assembly with silver engine casting and every lubricant BMW recommends, including part numbers for LOCTITE 638 and 243. That level of detail is why I keep a printed copy of this catalog on my bench.

ENGINE Section: What the Parts Catalog Covers

The ENGINE diagram (page 1 in the OCR extract) lists the silver engine assembly, the MR 70 developer, lubricants MP3 and sealing compound OMNI VISC. You see the rubber mounting, gasket LOCTITE options, and the motor oil spec: SUPER POWER 5W-40 or 20W-50. Each entry includes the supplement, quantity, and part number. If you need a dowel or a piston, the ENGINE HOUSING diagram (page 4) breaks down the oil level indicator, stud bolts M10×260.5, dowels, O-rings, and compression springs. That single page gives you the part number for the gasket ring A20×24-AL (07 11 9 963 340). No aftermarket catalog puts that in front of you with BMW’s own drawing.

SHORT ENGINE: Why You Need the Complete Assembly Breakdown

Page 2 lists the SHORT ENGINE assembly – part number 11 00 7 688 870. A short engine is the block with rotating assembly but no ancillaries. If you’re rebuilding, you need to know whether your short engine comes with or without the oil pump drive. This diagram shows it as a single unit. Compare that to the ENGINE VENTILATION diagram (page 5) which gives you the breather, O-ring 44×3, breather pipe, ISA screws M6×20, vent hose L=162, and hose clamp D=28mm. Having both diagrams on the same catalog means you can order the short engine and the breather system in one shot.

UNDERRIDE PROTECTION: Don’t Miss These Mounting Parts

The UNDERIDE PROTECTION diagram (page 3) covers the underride protection itself (11 11 7 674 123), rubber buffers M8 SW21 H15, bump stop 25×15, spacer, hex bolts M8×16-A2-70, flat washers, hex nuts M8-A2-70. If you’re installing a skid plate or underride guard, these are the hardware items you need. One missing hex bolt and the whole thing rattles loose on the trail. The catalog gives you the exact fastener grade and finish – M8×16-A2-70 is stainless steel, A2-70 tensile. That’s the kind of spec aftermarket books skip.

ENGINE HOUSING: O-Rings, Dowels, and Oil Level Indicator

Page 4 shows the ENGINE HOUSING with silver engine housing (11 11 7 668 226), oil level indicator, plug, stud bolts, dowels, O-rings, piston, compression spring, gasket ring, screw plug, and dowels of two diameters. Each dowel has a distinct part number – D=16 (11 11 1 340 910) and D=10.5mm (11 12 1 726 238). Mix them up and your engine case won’t align. The catalog’s exploded view prevents that.

ENGINE VENTILATION: Breather Pipe and Hose Clamp Specs

Page 5 gives you the ENGINE VENTILATION system: breather, O-ring 44×3, breather pipe, ISA screw M6×20, vent hose L=162, hose clamp D=28mm. If you’re replacing a cracked vent hose, you need the exact length (162mm) and the clamp diameter (28mm). The part number for the hose is 11 11 7 676 708. Order that instead of guessing a generic hose that collapses under vacuum.

3 Reasons This OEM Catalog Beats Aftermarket Parts Lists

First, the drawings are BMW-original – the same ones used by dealer parts departments. Second, each part number is cross-referenced with series K25 R1200 GS, so you won’t accidentally order a part from the K26 model. Third, the catalog includes supplemental information like lubricant recommendations and sealant types that aftermarket databases ignore. For example, LOCTITE 638 (07 58 9 056 030) is specified for gasket installation – you won’t find that in a third-party parts list.

Who Needs This Parts Catalog?

You need this if you’re a home mechanic rebuilding a GS engine, a shop doing warranty repairs, or a collector restoring a K25 R1200 GS to original condition. A parts catalog isn’t a substitute for a service manual – you still need torque specs and procedure steps. But when you’re ordering parts, this catalog is the source of truth. Pair it with a factory service manual like the BMW Motorrad R 1150 RT, R 1100 S EVO, R 1150 R Service Manual”>R 1150 service manual for the R1200 GS’s sibling models, or the BMW E31 E36 E32 E34 2009 User Manual – ISTA/P Documentation”>ISTA/P documentation for diagnostic procedures. Also check the BMW R 24-51 Parts Catalog – OEM Factory Parts Book”>R 24-51 parts catalog if you work on older BMW motorcycles.

Frequently Asked Questions

Does this catalog include service procedures like torque specs?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers only. For torque values and repair steps, you need the factory service manual.

How do I use the diagrams to order parts?

Find your component in the exploded view, note the reference number (e.g., 1, 2, 3) beside the description. Then look at the part number column in the table below the diagram. Enter that part number (e.g., 11 11 7 674 123) into BMW’s parts system or your dealer’s order screen. Verify the supplement and quantity – some parts are sold in multiples or as a set. The catalog also lists “From Up To” date ranges if the part was superceded. Always check those dates before ordering.

Will this catalog work for a BMW R1200 GS Adventure?

This catalog is specifically for the K25 R1200 GS (standard GS). The Adventure model (K25 with larger tank and different suspension) uses a separate parts catalog. Do not assume parts are interchangeable – always verify with your VIN and the correct Adventure parts catalog.

What is the difference between this OEM catalog and aftermarket databases?

Aftermarket databases combine parts from multiple brands, often omitting hardware like rubber buffers, washers, and gaskets. This OEM catalog includes every fastener, seal, and lubricant BMW specified for the R1200 GS. It also uses the original engineering drawings – no stylized illustrations that hide fastener orientation. If you’re rebuilding an engine, a missing O-ring can cause an oil leak. The aftermarket won’t show you that O-ring; this catalog does.
