In 1999, BMW continued the unique GS success story and introduced the R 1150 GS, which was a further developed R 1100 GS.
The model received new features such as a small and a large round headlight, a redesigned duck beak connected to the fuel tank, which was shorter and wider, and a reshaped windscreen and cockpit. The exhaust, which featured a modified manifold routing and a new silencer, in conjunction with the visual features, determined the bike's design.
A high recognition factor of the model was ensured by the cross-spoked wheels and the tank seat line through the luggage rack, which came from its predecessor.
The R 1150 GS featured a modified frame, and the flat-twin engine was increased in power by increasing the displacement to 1130cc, which had a power output of 85 hp with a peak at 6,750 rpm and 98 Nm (72 lb-ft) of torque at 5,250 rpm. With a curb weight of 249 kg (549 lbs) and a new six-speed manual transmission, the model registered a maximum top speed of 195 kph (122 mph).
The 1999 BMW R 1150 GS motorcycle came from the factory with standard features such as an adjustable windshield, a dual seat, a rear luggage rack, pillion grab handles, dual front disc brakes coupled to a single disc in the rear, a digital and analog instrument cluster, and a high-end suspension package composed of a BMW Motorrad Telelever on the front and a BMW Motorrad Paralever on the rear.
