My Australian '04 K1200RS bike’s I-ABS part number is 220.127.116.114.365.
I'm beginning to think all of the units are the same but with different part numbers. Is this a good assumption? Can anyone make sense of this?
- '03 K1200RS I-ABS units advertised on eBay in the U.S. have the same part number (18.104.22.1684.365).
- Microfiche records in Oz list the part number as 22.214.171.1245.801.
- Microfiche records in the U.S. list the part number as 126.96.36.1998.060 for '03 and '04 K1200RS bikes.
For most countries except USA , BMW began implementing the I-ABS system in various models starting in 2001. In USA it was only starting with 2002 models (although the production date at factory was sometimes mid 2001). Most R1150 boxer models also got their own implementation installed horizontally under fuel tank (instead of vertically like we have in K1200RS-GT).
As time went by, until end of production for K1200RS , K1200GT and K1200LT , FTE the OEM supplier of these I-ABS modulator did various improvements and design changes. Some changes are externally visible , others are inside the embedded software.
Each revision caused a number change (the FTE numbers on top of the unit). For a given BMW models, in 99% cases the various FTE units are compatible as far as installation is concerned. Of course you CANNOT take a unit from a Boxer models and install it in your K1200RS-GT
Any FTE unit from a K1200RS (2001-2005) or from a K1200GT (2003-2005) will work in your case. By far it is preferable to have a later unit as they have implemented what BMW refer to as “Energy Conservation Measures”. In these later units , starting late 2002 based on a Service-Bulletin, the software will shut down the rear brake pump when a certain pressure is reached – this only applied when parked at a stop light. This will minimize wear on the unit when only the rear brake pedal is used in these conditions.
See photo below for sticker on top of unit installed on K1200RS and K1200GT from 2003 to 2004. You may also find compatible units with number ending with "0036" to "0039". In addition to the FTE number starting with "S2AB9003" you need to pay attention to the model / type engraved in metal located in bottom corner (as circled Yellow in photo below). In general , BMW will only post the later models in their parts fiche and will supersede earlier units to this new part number (when it is compatible).
Note that later FTE units used on the so-called "slant-4" engine (K1200S, K1200GT , K1300GT) are not compatible as BMW implemented CANBUS system on these starting in 2005.
