If you dream of owning a tourer, a canyon carver, a trail bike, a ‘round-the-worlder, and a daily commuter, but your budget will stretch only as far as a single bike, don’t buy a lottery ticket––get a BMW R1200GS. You won’t be alone. The big boxer has topped BMW’s sales charts for years, and it’s easy to see why. At its debut in 2004, the 1200 took the stage 66 pounds lighter than the R1150GS it replaced, with about 20 percent more horsepower. The counterbalanced engine was substantially new, and a big jump in refinement over the 1150 Oilhead. BMW, wisely, left the basic concept alone: The 1200 is a fairly large evolutionary leap, but it clearly follows the GS lineage.
