A pad keeps the existing seat
Circulator 51076-10 is a large 16-inch-wide seat pad, not a replacement two-up seat. Its three-dimensional breathable construction is intended to encourage airflow where the rider touches the seat. An elastic under-seat strap and non-slip base secure the pad. A passenger pillion pad is a separate item; the listing describes how that optional pad joins the rider pad with hook-and-loop tabs. Choose this type of accessory when you want to retain the existing seating unit.
