3 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.
18V835000 · Power Train:Manual Transmission
Reported: 2018-11-27 (November 27, 2018)
Ducati North America (Ducati) is recalling certain 2017-2019 Ducati Monster 1200, Monster 821, SuperSport and SuperSport S motorcycles. The shift lever may have been incorrectly assembled, possibly resulting in the shift knob detaching from the lever.
Consequence: If the shift knob detaches, the rider may not be able to shift gears, increasing the risk of a crash.
Remedy: Ducati will notify owners, and dealers will inspect the gear lever shift knob tightness, replacing it as necessary, free of charge. The recall began January 14, 2019. Owners may contact Ducati customer service at 1-888-391-5446. Ducati's number for this recall is SRV-RCL-18-007.

Consequence: Air in the system may reduce effectiveness of the rear brakes, increasing the distance required to stop and the risk of a crash.
Remedy: Dealers will install new rear brake hoses, free of charge. Owner notification letters were mailed on June 28, 2021. Owners may contact Ducati customer service at 1-888-391-5446.
