In 1991, BMW released the R 80 GS alongside the R 100 GS, two enduro motorcycles that received a comprehensive facelift, noticeable through the new look. As standard, both models had semi-fairing bolted to the frame and external tubular bars derived from the cockpit fairing of the R 100 GS Paris-Dakar from 1989.
Visually, instead of the round headlight, the model packed a rectangular lamp taken from the K 75 S model. The instrument panel was integrated into the fairing, modified with two round instruments of the same size, and benefited from a rev counter. The windshield received a different shape and came tinted from the factory.
In addition, the handlebar controls were replaced with the K model controls, which featured turn signal actuation, and the safety tank cap from the /7 series was installed but reduced the fuel volume by two liters.
The 1991 BMW R 80 GS was taking its trust from a 797cc flat-twin engine with a power output of 50 hp at 6,500 rpm and 61 Nm (45 lb-ft) of torque available at 5,000 rpm. With a curb weight of 215 kg (474 lbs), the bike reached a top speed of 168 kph (105 mph).
It also came with standard features such as a dual seat, laced wheels, a small luggage rack on the rear, pillion grab rails, an analog instrument cluster, a blacked-out steel frame, and a center stand.
