The motor that built a legend. This Monsters on Machines design celebrates the iconic Harley-Davidson Knucklehead with a fully detailed V-twin engine, ghosted in blue flames and laced with skulls in the rocker boxes and cam cover. Cool metallic blues, deep shadows, and a dark backdrop give it a haunting, garage-wall poster feel in compact sticker form.
Built for riders who appreciate old-school Harley engineering and gothic artwork in equal measure.
