The Ducati Diavel will be officially revealed next month at the Milan EICMA show but thanks to the Ducati News Today, we can show you how the first prototype looked like. The pictures were taken 18 month ago in Los Angeles as the bike was created up for a trip back to Europe. This prototype has only one exhaust and a custom swing arm. The Diavel obviously evolved in the last 18 months and we are curious about the production version of Ducati’s big cruiser.
