2011 BMW F 650 GS Technical Analysis & Specification Breakdown
Built around BMW's enduro - offroad motorcycle platform, the 2011 BMW F 650 GS features a 798 cc (48.7 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 69.7 HP (50.9 kW) at 7,000 rpm while maximum torque reaches 75 Nm (55.3 lb-ft) at 4,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 87.3 HP per liter and a 2,500 rpm working window between peak torque (4,500 rpm) and peak power (7,000 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 F 650 GS measures 199 kg (439 lbs) wet (curb), translating to a power-to-weight ratio of 0.35 HP/kg (2.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,575 mm (62 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 3.7 L/100 km provides an estimated theoretical range of roughly 432 km (268 miles) between fill-ups, while factory top speed is listed at 185 km/h (115 mph).
