Hello,

I converted my K100rt fairing to an electric one. I love it and won't go back to a standard windshield.
If you are interested to convert yours, here is a very good deal. I found it on the ibmwr site and contacted the seller.
It seems that everything is there to convert your K100rt (even the switch).
The conversion is very easy and requires some minors modification such as grinding few milimeters of the fairing bracket and raising your instrument cluster by 1/2 of an inch.
for info, if you go to BMW and buy it new, the conversion cost over $2,500.
Here is your chance:

I believe they are a BMW salvage operation. I just purchased a front fork brace from them and awaiting its arrival.
