The BMW R 1200 ST is a replacement for the R 1150 RS, which was one of the most successful BMW boxer twins of recent years. With a particularly loyal customer base, the RS was voted Britain’s number one machine – the overall winner of RiDE magazine’s 2003 Rider Power survey. The R 1200 ST – Sports Tourer – retains the original’s groundbreaking versatility and rideability but provides more power, better handling, less weight, improved aerodynamics and increased weather protection.
