The current R1200GS descends from BMW’s original 1980 R80 G/S adventure bike. Combining liquid-cooling for the first time in division history, it also represented the highest-tech Bavarian boxer to date. The 1,170cc DOHC eight-valve engine produces a claimed 125 hp at a reasonable 7,700 rpm—plenty to shove the 525-pound machine down the road quickly. Its 180-degree crankshaft grants tractable power, while a balance shaft improves smoothness. The Adventure version adds wire-spoked wheels, 0.8 inch more suspension travel, a 49 percent larger (7.9-gallon) fuel tank, a flatter seat, crash bars, and unique finishes. Feel like exploring? The R1200GS has a 3-foot-high air intake just right for fording streams!
