I have a 2006 GL1800 Champion trike, and I would like to add a cup holder for the passenger. I do not have the arm rests.
The ones i have seen without the armrest mount, use the screw holding the passenger handle, however, due to the trike fender, there is not enough room for the cup holder to mound and hang properly.
I apologize if this thread has appeared before. I searched but didn't see anything.
