I've got the same backrest for my Street Glide. I don't really like that rack that's attached to it but that's just me. I'm sure it works just fine - just a matter of looks. I have the stealth rack, which IMO looks much better, that i can run with or without the backrest.
Current bikes in the stable:
2009 Street Glide
