Kawasaki is recalling certain model-year 2008-11 Ninja ZX-10R and 2009-12 Ninja ZX-6R motorcycles. A report from the National Highway Traffic Safety Administration says that due to a manufacturing error, the regulator/rectifier may insufficiently charge the battery. If the battery discharges, the motorcycle may stall without warning, the NHTSA report says.
Kawasaki dealers will replace the voltage regulator free of charge. The number of potential units affected is 20,544.
