Ducati XDiavel Thiverval by Fred Krugger Rennie Scaysbrook | July 3, 2017 Two time AMD Custom Bike Building World Champion, Fred Krugger, has released a new masterpiece based off the Ducati XDiavel. The machine is named the Thiverval after a small racetrack located just out of Paris and is possibly one of the most extreme versions of Ducati’s powercruiser ever created. The original lines created by the Ducati designers are still evident, with the engine in full view, while the trellis frame has been deliberately hidden from sight. Much of Krugger’s work centered around the tank and seat design, although Krugger elected to keep the iconic XDiavel headlight.
