2005 BMW K 1200 GT Technical Analysis & Specification Breakdown
Engineered by BMW for the touring motorcycle segment, the 2005 BMW K 1200 GT pairs a 1171 cc (71.5 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. 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 GT measures 300 kg (661 lbs) wet (curb), translating to a power-to-weight ratio of 0.43 HP/kg (2.33 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 1,550 mm (61 in) wheelbase engineered for planted straight-line stability. The 20.5-liter (5.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 200 km/h (124 mph).
