In 1989, BMW launched the K 75 RT, another version of the three-cylinder series with the main focus on loyal government customers, primarily police forces that used the R 80 RT boxer model in patrol duty and was ready to be replaced by a modern successor.
With this focus in mind, the BMW K 75 model was upgraded with the K 100 RT fairing and resulted in a handy K 75 RT gratefully received by the police departments. Also, for customers that didn’t care too much about the horsepower and the 1000s prestige, the model was a serious alternative to the K 100 RT/LT.
In 1996, the K 75 RT Ultima was a special model in a Cobalt Blue special paint finish with extended standard equipment, and just like its name says, it marked the end of the K 75 series.
The three-cylinder in-line engine that powered the 1989 BMW K 75 RT with a power output of 75 hp with a peak at 8,500 rpm and 68 Nm (50 lb-ft) of torque available at 6,750 rpm and the help of a five-speed manual transmission made possible for the bike to reach at a top speed of 185 kph (115 mph).
Standard features that came with the bike included a large windscreen, a half-fairing, a dual seat, an analog instrument cluster, a rear luggage rack, cast-aluminum wheels, and a center stand.
