2004 BMW R 1150 R Technical Analysis & Specification Breakdown
Built around BMW's naked motorcycle platform, the 2004 BMW R 1150 R features a 1130 cc (69 cu in) oil & air-cooled two cylinder boxer, four-stroke configuration. In factory specification, peak output is rated at 83.8 HP (61.2 kW) at 6,750 rpm while maximum torque reaches 98 Nm (72.3 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 74.2 HP per liter and a 1,500 rpm working window between peak torque (5,250 rpm) and peak power (6,750 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 1150 R measures 239 kg (527 lbs) wet (curb), translating to a power-to-weight ratio of 0.35 HP/kg (2.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,486 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 20.5-liter (5.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
