Hello, I am from Indonesia. My motorbike is Honda Supra GTR 150cc.
That's right, it is because the seat is very thin at first brougt. So i adding 2 foam layer into back seat , and 1 layer into front seat. So it is very comfortable for a long destination.I had to look closely at the picture, With the boxes open at first glance it looks like you have a double seat on the back
