Yes.. it is covered under extended warranty.. had left one on my 06 Ulra replaced - they found it doing the 10,000 mile service.. cost me $50
Extended warranty also paid to replace the HK radio.. the Aux Input jack broke off inside the radio, so I couldn't plug in my MP3 player.. whole radio was replaced for me - $50
So I guess the Ex Warranty was worthwhile.
I did read on one of the other forums that someone replaced the bracket with a sturdier one, only to find his fairing cracked later.. but it was only one post.
