Alright, this is the one. The blend of carbon fiber, machined aluminum, and leather is absolutely stunning. Limited to production of only 23 motorcycles, Arch is calling this a "concept production bike," probably because styling like this is only ever seen on concepts. A proprietary S&S 143ci engine (yes, that's 2,343cc) is housed in an entirely carbon-fiber MonoCell chassis. Developed as part of a new partnership with Suter Industries, the swingarm is single-sided and CNC machined with a carbon-fiber cover. SC Project—the same company that makes the exhaust for Marc Marquez's MotoGP bike—has developed a full titanium and carbon-fiber exhaust system that's incredible to look at, and, as you can hear in the clip below, it sounds absolutely amazing. The carbon-fiber wheels from BST were designed by Arch and are unique to this bike. I can only imagine what this beautiful, arty monster will cost.
