The electric windshield and shock upgrade might have been options on normal K75RT models but interest in revealing the truth about of this ancient marketing scheme is waning up here. :giggles
Everything is an option at BMW!
I don't think you could order a bike with electric windshield. Had to buy it afterwords and the price is enormous. Like fitting an ABS on an existing K. Possible but price is discouraging...
Mine does not have ABS, nor radio. No crash bars.
The shock was standard and the previous owner who spent ten years on K75 Gendarmerie bikes as a Gendarme, made the swap. For him the standard one was a crap.
To resume, as standard features on the RT Ultima was the electric windshield, the gauges, the blue seat, the color scheme with stripes ( grey for the RT , blue with white stripes for the naked) , the 3 spokes wheels.
On the naked one had the blue color the 3 spokes wheels and maybe the gauge. That is all.
In 1996 if you wanted à K75RT there was only the Ultima available.
