Whether a fork brace makes a difference depends on how hard you ride and how flexible your front end is. Shorter front ends with 39+mm tubes and good trees probably won't benefit much from one. I have an old Sportster with 35mm tubes and the "press fit" top tree (without pinch bolts), and a SE brace makes a world of difference in the twisties. I've never liked the look of a fork brace on long, extended forks, though. They're gonna flex anyway, so why clutter them up with a brace?

 

i PUT ONE ON MY 05 WIDEGLIDE DIDEN`T MAKE A DIFF TO ME ALSO I PERSONALY DIDEN`T LIKE THE LOOKS I THINK IT GARBAGES UP THE FRONT, I HAVE HTE 440`S ON REAR, WHAT IS ENVOLVED IN DOING THE FRONT WITH PROG , DO I JUST HAVE TO CHANGE OUT THE SPRINGS
