2009 BMW R 1200 GS Technical Analysis & Specification Breakdown
Built around BMW's enduro - offroad motorcycle platform, the 2009 BMW R 1200 GS features a 1170 cc (71.4 cu in) oil & air-cooled two cylinder boxer, four-stroke configuration. In factory specification, peak output is rated at 103.3 HP (75.4 kW) at 7,500 rpm while maximum torque reaches 115 Nm (84.8 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 88.3 HP per liter and a 1,750 rpm working window between peak torque (5,750 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the R 1200 GS measures 229 kg (505 lbs) wet (curb), translating to a power-to-weight ratio of 0.45 HP/kg (2.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,507 mm (59.3 in) wheelbase engineered for balanced agility and highway composure. The 20-liter (5.3 US gal) fuel tank paired with a rated consumption of 4.3 L/100 km provides an estimated theoretical range of roughly 465 km (289 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
