FST Platform/Seat

The seat is provided in a rider seat section and a passenger seat section.

The passenger seat can be released with the key, revealing a small tray (for tools, perhaps) and hooks for locking a helmet on each side of the tail.

The rider seat can be released by Torx (T15?) bolts that are at the front of the area under the passenger seat.

The SR/S seat differs from the SR/F seat, apparently in being broader and longer especially for the passenger.
