2005 BMW K 1200 RS Technical Analysis & Specification Breakdown
Engineered by BMW for the sport touring motorcycle segment, the 2005 BMW K 1200 RS features a 1171 cc (71.5 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 128.7 HP (94 kW) at 8,750 rpm while maximum torque reaches 117 Nm (86.3 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 109.9 HP per liter and a 2,000 rpm working window between peak torque (6,750 rpm) and peak power (8,750 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 K 1200 RS measures 285 kg (628 lbs) wet (curb), translating to a power-to-weight ratio of 0.45 HP/kg (2.21 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,550 mm (61 in) wheelbase engineered for planted straight-line stability. The 20.5-liter (5.4 US gal) fuel tank paired with a rated consumption of 4.9 L/100 km provides an estimated theoretical range of roughly 418 km (260 miles) between fill-ups, while factory top speed is listed at 286 km/h (178 mph).
