2018 BMW R 1200 RS Technical Analysis & Specification Breakdown
Engineered by BMW for the allround motorcycle segment, the 2018 BMW R 1200 RS utilizes a 1170 cc (71.4 cu in) liquid-cooled two cylinder boxer, four-stroke layout. In factory specification, peak output is rated at 125 HP (91.2 kW) at 7,750 rpm while maximum torque reaches 125 Nm (92.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and shaft drive (cardan) final drive. With a specific output of 106.8 HP per liter and a 1,250 rpm working window between peak torque (6,500 rpm) and peak power (7,750 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 R 1200 RS measures 236 kg (520 lbs) wet (curb), translating to a power-to-weight ratio of 0.53 HP/kg (1.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,527 mm (60.1 in) wheelbase engineered for planted straight-line stability. The 18-liter (4.8 US gal) fuel tank paired with a rated consumption of 4.6 L/100 km provides an estimated theoretical range of roughly 391 km (243 miles) between fill-ups.
