The 2021 Aprilia Tuono 660 has two recalls, both centering on the same critical engine defect: a connecting rod inside the engine can break, causing a sudden stall and loss of power while riding.
When a connecting rod fails, the engine stops without warning and cannot be restarted, leaving the rider without power in traffic or at speed, which raises the risk of a crash.
