Recall 21V315 affects 5,909 2016-2020 Ducati Monster, Supersport, and XDiavel motorcycles for air in the rear brakes. Repair is free at any franchised Ducati dealer.
Ducati is recalling 5,909 2016-2020 motorcycles across the Monster 797, Monster 821, Monster 1200, Supersport, and XDiavel lines under recall 21V315 because air can permeate the rear brake system. Air in the lines reduces rear braking effectiveness and lengthens stopping distance, so Ducati dealers will bleed and repair the rear brake system free of charge.

What's wrong?
The rear brake hose on these Ducati motorcycles carries pressurized brake fluid from the rear master cylinder to the ABS control unit. When the rider presses the rear brake pedal, fluid moves through this hose and clamps the rear pad onto the rotor. The hose has to hold pressure cleanly every time, with no air mixed into the fluid.
On affected Monster 797, Monster 821, Monster 1200, Supersport, and XDiavel motorcycles, the original hose material lets small amounts of gas pass through the hose wall over time. That gas collects inside the brake line as a pocket of air. Air compresses in a way brake fluid does not, so the rear pedal travels farther before the brakes bite. The problem grows worse during long stretches when the bike sits unused or when the rear brake is rarely applied during a ride.
If you notice the rear brake pedal sinking farther than normal during your pre-ride check, or the rear brake feeling soft on the road, that is the warning sign.
Who's affected?
Covers five Ducati model lines (Supersport, Xdiavel, Monster 1200, Monster 797, Monster 821) across five model years, all sharing the same rear brake hose routed between the master cylinder and the ABS control unit.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorcycle is included in this recall.
What's the safety risk?
Air in the rear brake system reduces braking effectiveness and lengthens stopping distance, which raises the risk of a crash. The change builds gradually, so a longer rear pedal stroke during a pre-ride check is the signal to stop riding and call the dealer before the next outing. Repair is free at any franchised Ducati dealer.
What should I do?
- Check your VIN to confirm your 2016-2020 Ducati motorcycle is included in this recall.
- Contact your nearest franchised Ducati dealer to schedule the rear brake hose replacement that fixes the air-permeation problem reducing rear brake effectiveness.
- Reference recall number 21V315 when you call the dealer or Ducati customer service so they pull the right campaign.
- Call Ducati customer service at 1-888-391-5446 if you have questions about parts availability or the owner notification letter.
- Ride cautiously until the repair is complete. Allow extra stopping distance and rely more on the front brake, since rear braking distance can increase.
What happens at the repair
At the dealer, a Ducati technician installs new rear brake hoses on the motorcycle. Parts and labor are free under the recall. If you previously paid out of pocket for a rear brake hose repair on your motorcycle, Ducati's standard reimbursement plan covers documented expenses. Bring your receipts and service records to the dealer when you arrive, or contact Ducati customer service to ask how to submit your documentation for review.

Recall 21V315 covers 5,909 Ducati motorcycles, including 2017-2020 Monster 797, 2017-2020 Monster 1200, 2018-2020 Monster 821, 2017-2020 Supersport, and 2016-2020 XDiavel models. Air can permeate the rear brake system, reducing rear brake effectiveness and increasing stopping distance.
What should I do if my 2016-2020 Ducati is on this recall?
Check your VIN to confirm your specific motorcycle is included in recall 21V315. If it is, contact a franchised Ducati dealer to schedule the rear brake hose replacement. Reference recall number 21V315 when you call. The repair is free. You can also reach Ducati customer service at 1-888-391-5446.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to perform the recall repair at no cost. Ducati dealers will install new rear brake hoses free of charge for every motorcycle included in recall 21V315, regardless of where it was originally purchased.
What is the safety risk?
Air in the rear brake system reduces rear brake effectiveness, which increases the distance required to stop and the risk of a crash. The dealer fix replaces the rear brake hoses and restores normal braking, so schedule the repair as soon as your VIN is confirmed in recall 21V315.
What if I bought my Ducati used?
The free repair still applies. Federal recall law requires manufacturers to honor the recall regardless of ownership history. If Ducati never mailed you a notice, check your VIN to confirm whether your specific motorcycle is included in recall 21V315, and reference that number when you call the dealer.
