Ducati is recalling the 2011-2012 Monster 1100 EVO because of potential cracks developing on the rear wheel spokes. The affected units have rear wheels labeled “DU6-RR“. Rims with the code “DU6N-RR” are not included in the recall campaign.

According to documents released by the National Highway Traffic Safety Administration, the spokes the rear wheel of some units may crack after intense use or after logging a lot of mileage, estimated by Ducati to be equivalent of six years’ worth of average use.

The problem was first identified in November 2011 during development of a different model which uses a similar wheel design (possibly the Streetfighter 848 which uses a similar 10-spoke 5.50×17 wheel). Ducati examined its Monster 1100 EVO test units and found one with 26,888 miles on it with cracks on two spokes.

To resolve the issue, Ducati designed a new wheel with supplier Enkei Thai. The new wheels are labelled “DU6N-RR” instead of “DU6-RR”.

Ducati dealers will replace the rear wheels on affected units at no charge to the motorcycle’s owner. The recall campaign affects 892 units.
