The 1999 R 1150 GS replaced the R 1100 GS, enlarging the four-valve boxer to 1130 cc and adding a six-speed gearbox with a tall overdrive top gear. It introduced the asymmetric 'fried egg' twin headlights and kept the Telelever front and Paralever rear. Mostly a long-distance road bike, it was still capable on gravel and light trails.
