There are three attachment points that are spring loaded. I didn't even realize it until my mechanic showed me, I thought they were ornamental. He's been in the Harley fix it business for years as a professional mechanic and he has no idea on who makes it. He's suggested that it was purpose built for the RK because of the design "V", same as on the seat. He's combed his catalogs and hasn't come across it.
I'd like to find out where it's from so I can purchase the attachments for it.
