2015 BMW F 800 GS Technical Analysis & Specification Breakdown
Engineered by BMW for the enduro - offroad motorcycle segment, the 2015 BMW F 800 GS relies on a 798 cc (48.7 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 85 HP (62 kW) at 7,500 rpm while maximum torque reaches 83 Nm (61.2 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 106.5 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the F 800 GS measures 214 kg (472 lbs) wet (curb), translating to a power-to-weight ratio of 0.4 HP/kg (2.52 kg per horsepower). Rider ergonomics and chassis geometry center around a 880 mm (34.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,578 mm (62.1 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 3.8 L/100 km provides an estimated theoretical range of roughly 421 km (262 miles) between fill-ups.
