Production Years:
The R 1150 GS was produced from 1999 to 2004. The 1994 reference in the product name might be an error or refer to a specific market variant or a manual covering a broader range that includes early concepts or related models if the original data is flawed. The R1100GS was produced from 1993-1999, and the R1150GS was its direct successor. This manual is likely for the R1150GS model range, but the year 1994 is inconsistent with the R1150GS production start. We will proceed assuming the manual covers the R1150GS generation.
Manufacturing Location:
Berlin, Germany
