What sort of riding do you plan to do - lots of longer distances on interstate, short hops around town, everything in between?
Some people just want a smaller fairing to keep the pressure off their chest, others want full coverage from any moving air as they ride in chilly temperatures, etc. Some want a frame mount (fixed) fairing for maximum protection and no wind-pushing-the-handlebars effect.
There are a number acrylic type fairings that work oretty well on these bikes, and others.
So, any more info you can provide about what you like and what you plan to do with it will help with what we can suggest.
