Yamaha Motor Corporation, USA is recalling 12,721 model year 2008-2011 WR250X motorcycles manufactured June 1, 2008, to June 1, 2011 and 2008-2015 WR250R motorcycles manufactured June 1, 2008, to June 1, 2015.
The insulation on the stator coil, a component of the alternator, may become damaged and short circuit to due insufficient heat resistance. If the stator coil is not insulated, the motorcycle will not charge and the battery will go dead, causing the engine to stall which increases the risk of a crash.
Yamaha will notify owners, and dealers will replace the stator coil with one that has sufficient heat resistance, free of charge. The recall is expected to begin in July 2015.
Owners may contact Yamaha customer service at 1-800-962-7926.
