Does anyone know how much work is involved in replacing the Gl500 seat with say a classic looking seat like a double up Triumph Bonneville seat? Triumph sells a seat that can convert to a single with a cowl or double rider with just two snaps on either side. I love the idea of this as my wife wont like it too much if I only have a single seat. I also will be making a cafe racer out of this bike and will be removing any unwanted metal that may stick out in the back. BTW its a 81 GL500.
