No, it's an artist's rendering.
Some of the things are derived from real parts that can be bought for the Bullet, or Electra models.
For example, that exhaust system(almost identical) is available for the Electra, but I don't think they make one like that for the UCE yet. But the Electra version exhaust is just like that, with similar(not exactly the same) basic bends, and going thru the left side toolbox just like that, with the same muffler and bracket. Woodsman II exhaust, I think they call it.
The front fender is available from Watsonian, on the trials kit.
The tank is a standard tank, with a custom paint job, and a stick-on knee pad set.
The seat is the traditional Bullet English dual-seat, and is available. The taillight set-up is available.
What's not available is the rear disc brake package, and the separate headlight system with twin clocks housed on top. Those are fictional.
You could actually make a bike very much like that, using an Electra, and having the paint job custom done.
Perhaps some of that same type aftermarket stuff might become available for the UCE over time.
