The defect
Piaggio Group Americas, Inc. (Piaggio) is recalling certain 2019-2020 MP3 500 motorcycles. The brake lines may have been improperly galvanized, allowing hydrogen to be released into the brake fluid.
The risk
Hydrogen in the braking system can reduce the brake lever's ability to activate the brakes, increasing the risk of a crash.
