Look through the renders of Barbra Custom Motorcycles and one thing is conspicuously absent — anything explicitly "retro". There are hints and nods to the past, but nothing could be mistaken for a modern refresh of a classic design. The Black Matter is a perfect example of Barbra's design language. Low and sleek with a minimalist appearance, the Black Matter is a glorious subversion of current trends. Now to find someone to build it.
