Finding the proper code for BMW bikes may be an confusing process.
Personally I start my search at realoem.com.
The bike in question, the K1200RS 'Taxi' entered the marked 1997.
By looking up the correct model, '51 Body Equipment/ 5120 Painted parts' reveals 'PAINTED PARTS 725 DAKARGELB/ARKTISGRAU.
The paint scheme code is 725.
Lookup Glasurit page:Glasurit Color-Online
and enter CODE: 725 and MANUFACTURER: BMW. Throw in MODEL: Motorcycle for good measure.( works without)
Now you get all the color within this code.
Mark Bayerisch... and you see 269 + 120 + 121 + 337
Fiddling about with 'Start Search' and 'Next' button, a new window pops up.
This window reveals the details.
In the case of the 'Taxi' 120 and 121 are two tones of black, most likely used on the frame (BMW have used 121 Matt black on many of their '90 s bikes).
Further: 337 is the Yellow color, and 269 is the grey color for the 'Taxi'
Puhh, now I want a beer
