I have one on mine and think that it tightens the forks up nicely. Although I guess I really should remove it one day and try it without the brace. It was on my bike before I triked it, put on by the previous owner. When I had my 1500, I added a Superbrace to that and it made a world of difference and reduced flexing. I have talked to a few owners and some dont see the need for it on the 1800's. I will stick with mine though. Also you will find some that say dont use a Superbrace. If you want to put a brace on the forks. Rather use the Traxxion or Kuryakyn because they are adjustable and easier to work with. IMHO, as long as the forks are installed and lined up properly, there is no need to have to adjust the brace and the Superbrace fits on it just fine.
