At the heart of the 2004 BMW R 1150 RT touring motorcycle, BMW utilizes a 1130 cc (69 cu in) oil & air-cooled two cylinder boxer, four-stroke layout. In factory specification, peak output is rated at 93.9 HP (68.5 kW) at 7,250 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 83.1 HP per liter and a 1,750 rpm working window between peak torque (5,500 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 1150 RT measures 279 kg (615 lbs) wet (curb), translating to a power-to-weight ratio of 0.34 HP/kg (2.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 25.2-liter (6.7 US gal) fuel tank paired with a rated consumption of 4.7 L/100 km provides an estimated theoretical range of roughly 536 km (333 miles) between fill-ups, while factory top speed is listed at 200 km/h (124 mph).
