The Sano Cover is the perfect canvas for you to customize with paint or a decal, and you can just turn it around if you ever want just plain black.


"I dig your air cleaners cause it's such a great platform to personalize your bike.  And you can do something different on either side and just flip from one side to the other for a different look.-Bart
