Though BMW has been making motorcycles since 1923, it wasn’t until 1983 that it manufactured its first four-cylinder motorcycle, the K 100, part of its K series of motorcycles. The first K 100, a naked bike, was considered radical and ultra-modern for the time. The K line would later become the flagship of BMW motorcycles. Two years later, in 1985, BMW introduced the K 75, a motorcycle with a smaller engine that remains popular today, even though it was last made in 1995. The K 1200 RS is another breakthrough bike for BMW; it was the first motorcycle in the K series to get Telelever forks. BMW had four models in its K line-up in 2008: K 1200 R, standard, introduced in 2007; K 1200 S, sport; K 1200 GT (Gran Turismo), and K 1200 LT (luxury tourer), both sport/touring motorcycles.
