Building off of three decades of tradition and 170,000 units sold worldwide, the 2013 BMW R1200GS has some big shoes to fill. Officially debuting today at the INTERMOT show, the Bavarians have kept most of what makes a GS a “GS” intact, while of course adding a much speculated, hyped, and rumored water-cooled boxer-twin motor into the mix.

The big push with the new model is its ability to meet stricter noise and emission standards, hence the move to liquid-cooling. Though, BMW says it also aimed to improve the R1200GS’s on & off-road performance, increase the bike’s safety, and of course continue the GS heritage that has basically defined the segment.

Using “precision cooling” derived from Formula 1, the 2013 BMW R1200GS only uses liquid cooling on the parts of the motor that need the additional heat exchange, thus allowing the engine still to use a high-degree of air-cooling, which BMW says helps justify the continued use of the boxer-twin motor design. Other changes include a wet slipper clutch and left-hand side cardan shaft drive. As we reported earlier, power is 123hp and 92 lbs•ft of torque at 6,500 rpm, while the curb weight is 525 lbs (238 kg) without fuel.
