Kuryakyn 7902 ISO Driver/Passenger Board Combo Set ISO&#174;-Boards are a great looking and comfortable alternative to the lackluster original equipment floorboards. Rubber ISO-ribs run the full length of the board providing both traction and comfort. Longer than stock length allows the rider to move their feet around while on long hauls. ISO&#174;-Passenger Boards complement the ISO-Boards perfectly. These boards were designed with comfort in mind for both you and your passenger.
