BMW's presentation of the BMW R 90 S in 1973 as the new flagship model of the revised /6 Series caused a sensation in the press. The machine clocked up a top speed of 200 km/h and ranked among the fastest series motorcycles in the world. This was also the first time that BMW Motorrad had commissioned a designer. Hans Muth styled the R 90 S with a profile setting it apart from other motorcycles in the marketplace and featuring the world's first series cockpit fairing attached to the handlebars, a tank design penned with flowing contours and the characteristic bench seat. Apart from Silver Smoke Metallic, BMW also supplied the motorcycle in a second livery of Daytona Orange from 1975 onwards and this became a favourite among collectors.
