Ducati is recalling 1,516 of its 2007 1098 motorcycles. The electronic control unit (ECU) ignition timing and idle mixture were improperly set during production, causing the engine speed to drop and stall the engine when temperature of the cooling system exceeded 180 degrees. If the engine stops while the motorcycle is being driven, it could increase the risk of a crash. Dealers will replace the ECU mapping using a dedicated diagnostic system instrument (DDS). The manufacturer has not yet provided an owner notification schedule. (NHTSA recall ID 07V-450.)
Triumph is recalling 4,696 of its 2004-2008 Rocket III and Rocket III Classic motorcycles. When the engine is returning to idle, an unmodified motorcycle may stall. If the motorcycle stalls, the rider will have to restart the engine, increasing the risk of a crash. Dealers will inspect and download new engine management software. The recall was expected to begin during October 2007. (NHTSA recall ID 07V-455.)
Big Dog has recalled 104 of its 2008 Mastiff, K-9, Ridgeback motorcycles. The fuel line can potentially contact heated metal parts of the motorcycle and melt. This condition could occur without any prior warning and could result in fuel leakage. Fuel leakage, in the presence of an ignition source, could result in a fire. Dealers have replaced the fuel line with a new fuel line that has higher thermal resistance properties. Also, the new fuel lines have been rerouted to further reduce exposure to heated metal. All motorcycles have been repaired. (NHTSA recall ID 07V-460.)
New recall information is posted monthly on the website of the National Highway Traffic Safety Administration.
