Look out for Bonj - he'll be asking why on earth you would choose to ride such an unstable, fad-driven, unpopular, too low to be seen, small wheeled, hard to start.... Ahhhh - you've already seen it!! LOL!!
If that bike's anything like a Ratcatcher, that isn't a fairing so much as an aerodynamically maximised tailbox, for carrying stuff. So it's not just for aerodynamics - although the tailed off shape helps to minimise the vortex behind.
Adding a fairing on the front would be possible, but might just make the bike too unwieldy for everyday use. Of course, Mikey might have a fairing, but just not fitted in the photo...
