OK this is primarily an excuse for me to gush about my gorgeous 1978 BMW R100S but also to pay respect to the great team at Untitled Motorcycles. Untitled is a workshop and garage underneath the railway arches in Camden, North London, where they specialize in customising old BMW air-cooled twins. They have been helping me get my bike into prime mechanical and weatherproof condition for the season. In the process we have discovered that this is a genuine R90S lookalike, off the factory line in Germany, and not someone's personal project which I had always assumed. After BMW stopped making the R90S in 1976, there was such a demand for the bike that they continued making the model but with the new 1000cc engine, as the serial number on my bike testifies.
The bike's visual design was overseen by Hans Muth, who was asked by BMW to create a machine with a unique presence far removed from the staid image offered by previous BMW offerings such as the R69S. This designer later went on to design the R65LS, and also the Suzuki Katana. DLK
