how does the circulator passenger seat pad fit to the pillion seat?

 

The velcro tabs on the front are supposed to attach to the front drivers velcro tabs.
Otherwise there is nothing that keeps it on.

 

The drivers pad has a strap that slides over the nose of the seat where it meets the gas tank. You have to buy a separate pad for the pillion. Also on the rear of the driver's pad the are Velcro tabs that will either wrap around the grab strap or connect to the passenger pillion.
I installed a drivers pad on my seat Tuesday so it's fresh in the head.
