2005 BMW R 1200 ST Technical Analysis & Specification Breakdown

Built around BMW's sport touring motorcycle platform, the 2005 BMW R 1200 ST features a 1170 cc (71.4 cu in) oil & air-cooled two cylinder boxer, four-stroke configuration. In factory specification, peak output is rated at 110 HP (80.3 kW) at 7,250 rpm while maximum torque reaches 115 Nm (84.8 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 94 HP per liter and a 1,250 rpm working window between peak torque (6,000 rpm) and peak power (7,250 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 R 1200 ST measures 229 kg (505 lbs) wet (curb), translating to a power-to-weight ratio of 0.48 HP/kg (2.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,502 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 21-liter (5.5 US gal) fuel tank paired with a rated consumption of 3.9 L/100 km provides an estimated theoretical range of roughly 538 km (334 miles) between fill-ups, while factory top speed is listed at 233 km/h (145 mph).
