I ordered these through my local Harley Dealer and Harley installed them. There is a clicking sound when going over bumps and applying front brake. When the bike is off and in a quiet area...and you push the bike and apply the front brake hard the clicking sound progresses to a binding spri g type sound.<br /><br />Harley contacted Legend and I am to ride the bike a 1000 miles to see if the noise goes away. So now I am the babysitter rather than the product be sound prior to sale and installation. At present time the Jury is out.
