2005 BMW K 1200 S Technical Analysis & Specification Breakdown
At the heart of the 2005 BMW K 1200 S sport motorcycle, BMW features a 1157 cc (70.6 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 164.9 HP (120.4 kW) at 10,250 rpm while maximum torque reaches 130 Nm (95.9 lb-ft) at 8,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 142.5 HP per liter and a 2,000 rpm working window between peak torque (8,250 rpm) and peak power (10,250 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the K 1200 S measures 248 kg (547 lbs) wet (curb), translating to a power-to-weight ratio of 0.66 HP/kg (1.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,571 mm (61.9 in) wheelbase engineered for planted straight-line stability. The 19-liter (5 US gal) fuel tank paired with a rated consumption of 4.7 L/100 km provides an estimated theoretical range of roughly 404 km (251 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
