Take the driver seat off with the key.
You'll see 2 small bolts at the front of the passenger seat. Don't worry about a nut behind them, it's tapped. Just remove those 2 bolts, and the seat comes right off.
That's one of the things I love about the Raider, turn the key and off it goes. My Suzuki Volusia seat had to be removed, starting with a bolt on the passenger seat.I was going to just replace it with a thumb screw, but i traded it in begroehand. Funny thing is, the day I bought the Raider, the salesman somehow "hinged" the main seat back towards the passenger seat, without taking it off. I could not duplicate what he did, I have to ask him next time I see him, when I pick up my Cobra Slashers next month.
