2004 BMW F 650 CS Scarver Technical Analysis & Specification Breakdown
Engineered by BMW for the allround motorcycle segment, the 2004 BMW F 650 CS Scarver 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 6,800 rpm while maximum torque reaches 62 Nm (45.7 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 76.7 HP per liter and a 1,300 rpm working window between peak torque (5,500 rpm) and peak power (6,800 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 CS Scarver 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 1,479 mm (58.2 in) wheelbase engineered for balanced agility and highway composure. The 17.3-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
