On the F800riders.org forum, there is a thread in the How To section on doing what is called the Front Brake Mod. Here's mine nice and close up all done. I did it about 1,000 miles ago and it's all good. No more high bracket!
It uses BMW parts mostly from the new K series.
Instructions are here: http://f800riders.org/forum/showthread.php?t=9386 but missing original pics. I do have a PDF of this with pics, and if you want it, PM me.
