You are right! I finally got the website to work and the F1 (and all sohc4 braces, for that matter) are gone. I love having a fork brace on my 500lb/35mm fork tube bikes...but beware! Without careful set-up of all the clamps on your front end, a fork brace can make the head shake worse! If you are worried about head shake, spend the money on a steering damper, not a forkbrace. A fork brace is just going to give a super solid, confidence inspiring feel when cornering and braking at the expense of increased stiction, especially if all the front end clamps (axle clamps, fork brace, lower triple, upper triple)may be slightly out of tolerance. I am guilty of buying a complete $800 750k1 just to get the ultra rare Telefix(german made, name may be wrong)fork brace that works on the short early fork lowers. I even offered the guy $250 for just the brace...nope, after that he suspected some kind of scam and would not even answer my messages. So I had a friend message him, showed up with $800 cash on an $1100 asking price and bought the whole bike.
