What's wrong?
The generator rotor, also called the flywheel, is a rotating part inside the 2021 Ducati Streetfighter V4 and Streetfighter V4 S engine. It spins with the engine and helps the charging system make electrical power for the motorcycle. The part has to stay intact while it turns at engine speed.
On affected motorcycles, cracks in the raw steel bars remained after the forging process used to make the rotor. Those cracks can stay inside the finished part until engine operation puts stress on it. If the rotor breaks, it can damage the generator cover and let engine oil leak out.
There is no warning sign before failure. Ducati's defect description says the failure can occur without any warning to the rider, so an owner should not expect a sound, light, or change in feel before the rotor breaks.
Who's affected?
Covers the standard and S versions of the Streetfighter V4, both tied to the same generator rotor (flywheel).

What happens at the repair
At the dealer, a Ducati technician inspects the production dates on the generator rotors, also called flywheels. If a rotor date falls within the affected range, the technician replaces the rotor before the motorcycle is delivered or returned. The recall repair is free, with parts and labor covered. Ducati said all affected motorcycles were still in dealer inventory when the recall began on August 12, 2020. Ducati's general reimbursement plan is on file for documented out-of-pocket repairs connected to this recall, so ask Ducati customer service how to submit paperwork if you already paid for a related generator rotor repair.
