Wheel swapping is limited by a few mechanical features which result in different wheel dimensions. The wheel configuration is affected by things like:
I started this project trying to figure out which 5-spoke wheels I could fit to my R1100RS, and uncovered a large variety of wheel configurations. Find a wheel with the same features and geometry as the one you have, and you have a good candidate for a swap. Please note that there is a lot of information to be considered and some of this may be inaccurate. It is a good starting place if you're trying to find out what wheel works with what bike (like if you see some mystery wheel on eBay or at a flea market).
R1200C and "CAN-bus bike' wheels are skipped, as they are basically non-interchangeable with other BMWs. Fronts might be.
Note: Cast ABS rings are for ABS2, and slotted stamped ABS rings are for iABS. I have successfully used a slotted ABS ring on my ABS2 front brake, and a friend has successfully used a cast ABS ring on his iABS rear brake. Hoever, this should not be taken as a guarantee that they are compatible. Safety dictates that you should observe the wheel speed sensors with an oscilloscope and satisfy yourself that an adequate signal is being reliably sent to the ABS unit.
If you find an error or have additional information, please let me know. However, please DON'T ask me what will or won't work. Anything I could tell you would come from the information here. You need to figure it out. If you can't, you shouldn't be messing with the wheels.
These are the same for K and Airheads, and accept fixed 285mm brake rotors which mount with 4 bolts near the center of the wheel. Bearings accept 25mm axles.
K75 and K1100LT used bias-ply tires and had different dimensions. The radial-tired K1100RS, K1, K100RS-4V and R1100 used rims of the same dimensions. In addition to silver, K11RS rims were available in gold, K100RS-4V were available in white, and all K1 rims were yellow.
The Oilhead front rims have the speedo drive flange and the K fronts do not. For radials, the front ABS ring has 6 tabs and mounts to the left brake rotor carrier.
The radial rear rim is dimensionally the same for Ks and Oilheads. The brake rotor and ABS ring mount to the hub, not the rim.
For Oilheads, especially the R1100S and the different R1150R variants, these rims are now available in many colors.
Early 5-spoke wheels had shorter mounting standoffs on the left side for ABS versions, because the 5mm-thick cast ABS ring is mounted between the brake rotor and the standoff. These measure 111.5mm across the rotor mounting surfaces whereas the non-ABS measured 116.5mm. Later versions were all 116.5 because the stamped ABS rings had very thin mounting flanges. With the stamped ABS ring on the left and a washer on the right, the new rotors are actually 118mm apart. Most R1150 models have the speedo drive fitting (R11S, Rockster and K12 don't) and K1200LT front wheels have heavier flanges. All accept 20mm axles.
R1100S and R1150 have standoffs for mounting the brake rotor to the wheel, and have a much greater offset (much thicker mounting flange). Early R1100S wheels are ABS-specific due to the mounting thickness of the ABS ring ("short" indicated below). K12 has the brake rotor mounted on the hub like the older R1100 bikes have. These are all available in 5" and 5.5" sizes.
