The legendary Shinya Kimura’s Zero Engineering and Taiwan-based Rough Crafts recently came up with this sweet project based on an S&S Harley Knucklehead engine. Blending a dark, gothic look with brassy Victorian accents, the custom employs a Type 6 frame from Zero, along with numerous other bits including the seat and springer forks.

While the guys at Rough Crafts wanted to fit the bike with an exposed battery, Yeh later came up with a box that could house a smaller and more efficient Lithium-Ion battery and the master cylinder. What do you think of it?
