The CS_05 Zen, the latest creation by Portuguese custom bike builder it roCkS!bikes, is the lovechild of a partnership between the Portuguese branch of Yamaha Motor Europe, Motociclismo magazine and the custom shop from northern Portugal.
Alexandre Santos and Osvaldo Coutinho transformed the Yamaha SR400, using their trademark monocoque design to create their Yard Built interpretation of the classic Yamaha. Inspired by the early flat trackers, the Zen employs the distinctive design characteristic of the Portuguese custom builder, the single piece tank, seat and tail.
