Theres a kit out there that converts your banshee to a three wheeler, by using a motorcylce style swingarm with a single tire, they also make it for other bikes. I dunno if its still around or not but it was in dirtwheels mag awhile back. That kit would be all you need to make your banshee street legal in PA other then the obvious, DOT tires, turn signals, a mirror, and a horn.
