2021 Bmw F 850 GS Technical Analysis & Specification Breakdown
Positioned in Bmw's enduro - offroad motorcycle lineup, the 2021 Bmw F 850 GS utilizes a 853 cc (52.1 cu in) liquid-cooled twin, four-stroke layout. In factory specification, peak output is rated at 90 HP (65.7 kW) at 8,000 rpm while maximum torque reaches 86 Nm (63.4 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 105.5 HP per liter and a 1,750 rpm working window between peak torque (6,250 rpm) and peak power (8,000 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 850 GS measures 229 kg (505 lbs) wet (curb), translating to a power-to-weight ratio of 0.39 HP/kg (2.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,593 mm (62.7 in) wheelbase engineered for planted straight-line stability. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 4.1 L/100 km provides an estimated theoretical range of roughly 366 km (227 miles) between fill-ups, while factory top speed is listed at 201 km/h (125 mph).
