I assume you're talking about the black vinyl lid covers from HD. I had them on my SG because I didn't want my wife or kids to scuff the bags when they mounted the bike (like they did on my FLHRC). I liked the looks of them, but the adhesive on the velcro softened up the first month they were on and they started getting loose. I ended up taking them off because they slid around when the adhesive got hot.

 

Mine are the Kuryakyns. They seem to be holding pretty tight.

 

DITTO, I also got the fairing bra.. Like the looks and bugs come off easy.. Harley should have made the inside velcro parts black instead of white.. WTF..!!!

Just saw a Kuryakyn set this am with the flame skull embroidered on the fairing lids..(my buddies bike.. says they cost him about 80 bucks.) and black velcro attachments.. !!
Not that I would go that way.. but neat..
