Utopia Has One
Freak..... First, thanks for the pictures of your new baby. I noticed you weren't smiling at all but once you start riding.....the grin appears before you notice. Let us all know how you like the power and comfort after you've spun it around town a few times.
Now....on to your question. I bought a backrest from Utopia:

The brace bolts into the three holes used for the pillion so if you're riding alone, just use the pre-drilled holes. A single bolt is used to put on or take off the backrest and it's adjustable for height and forward/backward movement.
