+1 the bikes with the bigger tubes, don't need a fork brace you won't notice the difference. I had a flat recently and had to have the real tire taken off and the tube replaced. Now my rear end is not a sensitive to sudden direction changes. I had always kept the pressure up so I know that is not the issue. I think the bike came from the factory improperly aligned and now it is good.
So for the moment True-Trac or Positrac on hold.

 

Mostly. But when you've got something like my "new" '87 FXR/SP with a Wide Glide Front end on it, you better throw on a fork brace. Sometimes even when everyhting on the bike is right, they can help some with some of the weird groves they're putting in some roads nowdays.

By the way - I got it with 20300 orig. miles, not a scratch on it, literally everything that can be chrome was, had those aircraft type metal wound cables, and that VIN lookup thing says it's been at the HD dealer every year since it was born (alhough THAT will change now, I've got my own tools and stuff). For $4800. Eat your hearts out
