What's wrong?
The regulator/rectifier on 2008-2012 Kawasaki Ninja ZX-6R and Ninja ZX-10R motorcycles is part of the charging system. It changes power from the alternator into battery-ready current and keeps voltage in the correct range while the engine runs. The battery then supports starting, lighting, ignition, and other electrical loads.
On affected Kawasaki motorcycles, a manufacturing error allows the regulator/rectifier to charge the battery too weakly. The bike keeps drawing power, but the charging system does not replace enough of it during normal riding. As the battery drops, electrical power becomes less dependable, and the motorcycle can be left with too little charge to operate normally.
There is no warning sign before failure. Do not rely on a specific sound, light, or ride feel to tell you the regulator/rectifier has stopped keeping the battery charged.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific motorcycle is included.
What's the safety risk?
A discharged battery can make the motorcycle stall without warning, which increases crash risk because power loss can happen before the rider has time to react. Until the voltage regulator is replaced, avoid unnecessary rides and arrange service soon. Repair will be free at any franchised Kawasaki dealer once available.
What should I do?
- Check your VIN to confirm your 2008-2012 Kawasaki Ninja ZX-6R or Ninja ZX-10R is included in this recall.
- Watch for Kawasaki's owner notice if you have not received it; notices were mailed on February 24, 2012.
- Contact a franchised Kawasaki dealer and reference recall number 12V064 when asking about the free voltage-regulator replacement.
- Call Kawasaki customer service at 949-770-0400 if the dealer needs help confirming the recall for your VIN.
- Avoid riding until the voltage-regulator repair is complete because a discharged battery can stall the motorcycle without warning.
What happens at the repair
Kawasaki's remedy is a free voltage regulator replacement. At the dealer, a Kawasaki technician replaces the regulator/rectifier that can leave the battery undercharged, then checks that the charging system is working as intended. Kawasaki's filing says the safety recall began on February 24, 2012, but this input does not give a confirmed current repair status. Parts and labor are covered under the recall once the repair is available through the dealer.
