In the attached article I describe the replacement of the fork tube or submersible tube Simmerrings at the BMW R1100 RT from the year 2000 (type 259). The principle and the order of the work can certainly also be applied to other fork tubes or submersible tubes. For the successful work it is necessary to make a small tool. As it is manufactured results from the article. Many greetings to all and a lot of success with the screw.
