I have or had a top box on my Xciting 500. I left a friends house and took my helmet from the back of it. I drove up the road, about 5 miles, to meet the GF at a bar for a drink.
I take off my helmet and go to place it in the top box. ONLY THE TOP BOX IS GONE!!!
I drove back the way I came 3 times looking for it and it was gone.
Still not a clue what happened to it.
