2004 BMW F 650 GS Dakar Technical Analysis & Specification Breakdown
At the heart of the 2004 BMW F 650 GS Dakar allround motorcycle, BMW relies on a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 50 HP (36.5 kW) at 6,500 rpm while maximum torque reaches 60 Nm (44.3 lb-ft) at 4,800 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 76.7 HP per liter and a 1,700 rpm working window between peak torque (4,800 rpm) and peak power (6,500 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 F 650 GS Dakar measures 187 kg (412 lbs) dry, translating to a power-to-weight ratio of 0.27 HP/kg (3.74 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,479 mm (58.2 in) wheelbase engineered for balanced agility and highway composure. The 17.3-liter (4.6 US gal) fuel tank paired with a rated consumption of 3.2 L/100 km provides an estimated theoretical range of roughly 541 km (336 miles) between fill-ups, while factory top speed is listed at 170 km/h (106 mph).
