Report Receipt Date: June 29, 2015

Component(s): Electrical System
Potential Number of Units Affected: 12,721
Manufacturer: Yamaha Motor Corporation, USA
THE RECALL: Yamaha Motor Corporation, USA (Yamaha) is recalling certain model year WR250X motorcycles manufactured from June 1, 2008, to June 1, 2011, and WR250R motorcycles manufactured from June 1, 2008, to June 1, 2015. In the affected motorcycles, the insulation on the stator coil, a component of the alternator, may become damaged and short circuit to due insufficient heat resistance.
WHAT COULD HAPPEN: If the stator coil is not insulated, the motorcyle will not charge and the battery will go dead, causing the engine to stall which increases the risk of a crash.
THE FIX: 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.
