There are custom bikes and then there are amazing custom bikes. This one fits in the second category from obvious reasons. It is a Harley-Davidson customized by Horst Dzhangmen in a unique way during three long years. Long story short, all parts were cut in the form of hexagon, apart from the Shovelhead 1340 cc engine, transmission and modified frame, which are all original H-D parts.
Looking for a reason to why would someone spend that amount of time handcrafting parts for such a bike? No special reason. This is just another way to stand out.
