ON 03/14/2019 WHILE RIDING THE MOTORCYCLE DURING THE DAY I EXPERIENCED A SUDDEN COMPLETE FAILURE OF THE REAR BRAKE SYSTEM WHILE NAVIGATING A TURN.

THE MOTORCYCLE STALLS WHEN COMING TO A STOP SINCE IT WAS NEW (PURCHASED MAY 2018), WITH THE CLUTCH ACTIVATED AND BIKE STILL ROLLING. I HAVE ALL DEALER SERVICE RECORDS AND VIDEOS DOCUMENTING THIS ISSUE. SEVERAL OTHER PEOPLE ON DUCATI FORUMS HAVE ALSO REPORTED THE SAME ISSUE. DEALER WAS UNABLE TO DIAGNOSE, AND DUCATI NA WAS UNABLE TO RESOLVE. I DEALT WITH THIS FOR ALMOST 2 YEARS UNTIL THE MOTORCYCLE WAS RETURNED TO DUCATI AS PART OF A LEMON LAW BUYBACK.
