Hello fellow Road Glide enthusiast. I recently joined this forum and find the wealth of info so helpful. I just installed KST Kustoms 12" Mayhems. Thanks to Donk and others who have left nuggets on here, this project went pretty good for a rookie... Beer was a must... I've been riding my current 2012 Road Glide Custom for 3 years and it just gets better with time and money.
