In 1984, the German maker released the BMW R 80 RT, a new addition to the mid-range tourer range, which retained the frame concept from the R 80 with a single-sided swingarm, wheels, and brakes.
The extensive innovations of the RT with the large touring fairing had a clear effect and made the new version more active than the previous model with the R 100 RT chassis.
Due to the Monolever suspension, the R 80 RT had a reduced curb weight of 227 kg (500 lbs), and a modified engine tuning with a new exhaust system made the model livelier than its predecessor.
In the visual department, the 1984 BMW R 80 RT Mono had a new front mudguard, side covers, and seat that played a good part and made the model look more dynamic and younger than its predecessor.
The thrust came from a 797cc flat-twin engine that delivered an output power of 50 hp at 6,500 rpm and 60 Nm (44 lb-ft) of torque with a peak at 3,500 rpm. A five-speed transmission sent the power to the rear wheel through a final shaft drive, pushing the bike to a top speed of 170 kph (106 mph).
As standard features, the bike came with a one-piece dual seat, a passenger grab handles, a large windscreen, a half-fairing for increased protection against the elements, laced wheels, dual front 285 mm disc brakes coupled to a 200 mm rear drum unit, an analog instrument panel, and a center stand.
