Piaggio is issuing a recall on its Fly 50 scooter and Vespa’s LX50 and S50 models due to a potential failure in the ignition control unit. The three scooters use the same four-valve four-stroke engine and may be subject to the same problem.

According to documents filed with the National Highway Traffic Safety Administration, the capacitor discharge ignition (CDI) unit on the affected scooters may fail, altering the ignition timing. This may lead to airbox backfire and a potential fire hazard.

Piaggio has secured a replacement CDI unit from a supplier and authorized dealers will replace the unit on recalled models at no charge.

The recall affects 265 Piaggio Fly 50 units from model years 2011-2012, 702 Vespa LX50 units from 2010-2012 and 1,180 Vespa S50 units from 2009-2012.
