Piaggio Group Americas is recalling 123 model year 2019-2020 MP3 500 motorcycles.
The brake lines may have been improperly galvanized, allowing hydrogen to be released into the brake fluid.
Hydrogen in the braking system can reduce the brake lever's ability to activate the brakes, increasing the risk of a crash.
What to do
Piaggio will notify owners, and dealers will perform a complete brake system flush free of charge.
The recall is expected to begin September 24, 2020.
Owners may contact Piaggio customer service at (212) 380-4433. Piaggio's number for this recall is PP2ZZQ1904_MP3.
