Ducati is recalling the XDiavel S because the rear wheels may have been installed incorrectly. Only S versions of the XDiavel are affected, as they use a different rear wheel design than the base models. The recall affects 925 units in the U.S., all produced from Nov. 25, 2015 to May 18, 2016.
The XDiavel S’ four rear wheel shaft driving pins are supposed to fit into holes in the rim (highlighted in green in the diagram below). The wheel design, however, has four oblong slots in the spaces between these holes. On some models, the shaft driving pins may have been inserted into these recesses instead of the intended holes (highlighted red in the diagram).
If the pins were improperly lined up, the pins can rotate within these recesses. Units with this problem may make a metallic noise during acceleration or deceleration. The photo below illustrates the potential damage the drive pins may inflict on the wheel. If left unaddressed, this may cause the drive pins to fail, resulting in a loss of power delivery and braking ability, increasing the risk of a crash.
Ducati first received a field report about this problem in March when an XDiavel S in Europe made a loud noise during acceleration. Ducati received three more reports from Europe in April with the same complaint. Ducati then began an analysis of the rear wheel design and production process and identified the problem. On May 20, Ducati began worldwide recall proceedings.
Dealers will inspect recalled units and replace any rear wheel rims that were installed incorrectly. Dealers will also install rubber inserts into the recesses which would prevent the drive pins from being incorrectly installed into them. The rubber inserts will be added to new production models while future models will have a new rim design to avoid this issue.
