2002 BMW R 850 R Technical Analysis & Specification Breakdown

Engineered by BMW for the naked motorcycle segment, the 2002 BMW R 850 R relies on a 848 cc (51.7 cu in) two cylinder boxer, four-stroke powerplant. In factory specification, peak output is rated at 70 HP (51.1 kW) at 7,000 rpm while maximum torque reaches 77 Nm (56.8 lb-ft) at 5,500 rpm, transferring power to the rear wheel through shaft drive (cardan) final drive. With a specific output of 82.5 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 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 850 R measures 235 kg (518 lbs) dry, translating to a power-to-weight ratio of 0.3 HP/kg (3.36 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 18-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 187 km/h (116 mph).
