2023 KAWASAKI NINJA ZX-4 Recalls — Canada & USA

The 2023 Kawasaki Ninja ZX-4 has two recalls, both involving engine defects that can cause the motorcycle to stall without warning while riding, raising the risk of a crash. One issue involves spark plugs that may have been damaged during production, causing an unstable idle, hesitation, or sudden power loss. The other involves an alternator rotor bolt that may not have been properly tightened, allowing the rotor to work loose and cut engine power while the bike is in motion.
