How do I remove the seat on a 1991 Honda 250 Nighthawk?

On the gearshifter side of the bike, in front of the rear turn signal is a lock and loop thingy. That is for locking the helmet. But, if you turn the key as though you are going to lock the helmet, and push a lever next to it, the seat will unlock. I believe you move the lever towards the front of the bike. The key will stay in the lock when you are in this mode. Give the seat a pull on the passenger strap. The seat will pop off. Put back on by looking under the seat when reinstalling it. You'll put it back on by putting the drivers end of the seat first, then the passenger part.

There is a storage compartment under the back of the bike, accessible by taking off the seat.

I've had one of those since 1991. Actually you turn the key as though you were going to unlock the helmet. There is a tab beside the helmet loop and you push that down. While holding that down pull up and back on the seat strap. You can remove the key once the seat is removed.
