1998 BMW R 1100 GS Technical Analysis & Specification Breakdown

At the heart of the 1998 BMW R 1100 GS allround motorcycle, BMW utilizes a 1085 cc (66.2 cu in) two cylinder boxer, four-stroke layout. In factory specification, peak output is rated at 80 HP (58.4 kW) at 6,750 rpm while maximum torque reaches 97 Nm (71.5 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 73.7 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.

Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
