1999 BMW R 1100 RT Technical Analysis & Specification Breakdown

Built around BMW's touring motorcycle platform, the 1999 BMW R 1100 RT features a 1085 cc (66.2 cu in) oil & air-cooled two cylinder boxer, four-stroke configuration. In factory specification, peak output is rated at 90 HP (65.7 kW) at 7,300 rpm while maximum torque reaches 95 Nm (70.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 82.9 HP per liter and a 1,800 rpm working window between peak torque (5,500 rpm) and peak power (7,300 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 1100 RT measures 290 kg (639 lbs) wet (curb), translating to a power-to-weight ratio of 0.31 HP/kg (3.22 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 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 26-liter (6.9 US gal) fuel tank paired with a rated consumption of 6.8 L/100 km provides an estimated theoretical range of roughly 382 km (237 miles) between fill-ups, while factory top speed is listed at 211 km/h (131 mph).
