The 2019 and 2020 Kawasaki Ninja ZX-10R are subject to a recall issued by Kawasaki Motor Corp. In all, close to 1,530 units are affected by the recall. On affected units, the engine could backfire while shifting under high engine loads when the Kawasaki Quick Shifter (KQS) is activated, potentially resulting in damage to the air suction valves. The blowback of high-temperature exhaust gas from continued use could result in additional damage to surrounding parts and create the potential for a fire.
Kawasaki is alerting all registered owners of affected motorcycles and instructing the dealer network to repair the ECU by reprogramming it and replacing the air suction valves.
