Triumph is recalling a number of its models for faulty engine control units (ECUs), which may improperly activate the bikes’ fuel injectors.

The recall affects the 2014 and 2015 model year Triumph Thunderbird, Thunderbird ABS, Tiger 800,Tiger 800 ABS, Thruxton, and Bonneville motorcycles manufactured between February 6, 2014 and August 7, 2014.

It’s not clear how many total motorcycles this recall affects, as Triumph lists the number currently as “0” with NHTSA, but given the number of models involved and the wide timeframe given on the production dates, we would expect a massive number of motorcycles to be involved.
