The 2020 Ducati Monster 821 has two recalls, both involving the rear brake system and both raising the risk of a crash if left unaddressed.
The more serious issue involves the rear brake hose, which can suffer heat damage and cause the rear brakes to fail entirely. The second recall involves air working its way into the rear brake hydraulic system, which reduces braking effectiveness and extends stopping distances. Both issues affect the same circuit, so riders may notice a soft or unresponsive rear brake pedal as a warning sign of either problem.
