The Telefix was an aftermarket stabilizer and there continue to be decent copies of it. The reviews for them have been favorable i.e., they make somewhat of an improvement, but a stabilizer is unlikely to correct the degree of wobble that is described in your post.

What you can do right now is adjust the steering head bearing. With the Brick's front wheel centered and off the ground, the fork should slowly and smoothly turn to full lock in either direction when the handlebar is released and slightly nudged. If it swings rapidly or not at all, the bearing either needs adjustment or replacement. Complete instruction can be found in the BMW K75/K100 workshop manual downloadable from this site.

If the handlebar can be moved fore and aft slightly when pushing or pulling on it when the wheels are off the ground, the bearings are worn. Bearing condition and incorrect adjustment can cause wobble when the tires contact pavement irregularities at speed.

Check the fork tube alignment by laying a pane of glass that is as wide as the fork tubes' horizontal outside dimension and sufficiently long enough to cover much of the tubes' clear length. Both tubes should make full contact with it. If they don't, the fork has stiction that affects the freedom of the fork tube's compression and rebound. That will also cause wobbling and weaving. The tubes must be in the same plane for the suspension to work well.

Sounds fun! Take care out there.

Hey Kris, I just installed new springs and gold emulators on my 92 K75S. I would not say my front end was wobbly but it made it feel a lot more stable. How is your tire? Is your fork oil old and have you serviced them? I ordered one of those fork braces for my 87 from that place and it took over a year to get it. I thought they lost it and then I finally received it. I would not say it made a huge difference. Hope that helps some.

Does anyone have an opinion on the installation of fork braces? I have an '86 K100RT that I stripped naked. (weight consideration) On highway off ramps, for example, if I hit some bumpy spots, my front end wobbles like a drunken sailor on shore leave. Not a good feeling. Any comments are welcome. I see a company in Italy still offers braces for the front end and I'm wondering how effective it might be. Thanks in advance!
