Congratulations!
Best way to remove the seat on the X2 is to tip the dump bed and lift the rear of the seat. Word of warning too - don't haul it with the second seat up or you will lose your seat! The dump bed and rear seat is all that holds the front seat on. I usually put a strap over the seat when I am hauling it just to be on the safe side. My brother lost his seat, first day, just driving from the dealer.

When putting the seat back on carefully align the seat so you don't push in the rubber grommets on the bottom of the seat.
Hope you enjoy your X2 as much as I have mine. The longer wheel base makes for a much smoother ride. Safe riding.
