Cross-purposes exist within the Open class as well. At Dorna's urging, Honda has developed a price-controlled "production racer" version of its RC213V (called the RCV1000R, and costing more than 1 million euro) to help fill the grid. Yamaha—with a special dispensation by Dorna—has taken a different path to support the Open class and will lease (not sell) engines very near Factory specification, including pneumatic valve springs, to be housed in independently constructed prototype chassis (but will provide temporary use of 2013 frames and swingarms to get this effort off the ground). A third manufacturer, Ducati, was presumed to be a full-Factory team but at press time was openly considering abiding by Open rules, enticed by the potential benefit of 24 liters and 12 engines. Such complexity!
