2009 BMW F 800 S Technical Analysis & Specification Breakdown
Built around BMW's sport motorcycle platform, the 2009 BMW F 800 S relies on a 798 cc (48.7 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 83.8 HP (61.2 kW) at 8,000 rpm while maximum torque reaches 86 Nm (63.4 lb-ft) at 5,800 rpm, transferring power to the rear wheel through a 6-speed gearbox and belt final drive. With a specific output of 105 HP per liter and a 2,200 rpm working window between peak torque (5,800 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 800 S measures 204 kg (450 lbs) wet (curb), translating to a power-to-weight ratio of 0.41 HP/kg (2.43 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,466 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 3.4 L/100 km provides an estimated theoretical range of roughly 471 km (293 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
