Triumph is recalling several 2014 and 2015 motorcycles because of a problem with the engine control units. The recall affects the Bonneville, Bonneville T100, Thruxton, Scrambler, Tiger 800, Tiger 800XC, Speedmaster, America, Thunderbird, Thunderbird Storm, Rocket III Touring and Rocket III Roadster. As of this writing, recalls have been announced in the United Kingdom, Australia and Canada but we expect a similar recall in the next few days for the U.S. market.
According to Transport Canada, the ECU may inadvertently activate one of the fuel injectors, causing it to fill one of the engine cylinders. This may cause the affected motorcycle to fail to start or, if the motorcycle is already operating, may cause one engine cylinder to lose ignition due to excessive fueling. The U.K.’s Vehicle and Operator Safety Agency the problem is caused by ECU components which may be “incompatible when operating at extremes of tolerance”.
Triumph dealers will correct the problem by replacing the ECU on affected units.
We will provide more information when the National Highway Traffic Safety Administration announces a similar recall for the U.S.
