This concept design for a futuristic Harley-Davidson motorcycle looks like a combo of a street bike from today and Batman's Batcycle from The Dark Knight. And you know what? There are certainly worse places to draw inspiration from.
The design itself is, like most concept designs, low on details on how this thing would actually run, but that's OK. They have 10 years to figure it out. For now, we can just enjoy the eye candy.
