The 2021 Kawasaki Ninja H2 SX has 3 recalls, the most serious being a dry rear hub needle-bearing that can lock up the rear wheel without warning, raising the risk of a crash.
Two engine-related recalls round out the list. In one, a software or mechanical condition can cause the engine to stall while riding. In the other, the oil pressure relief valve can come apart internally, causing a sudden loss of oil pressure that can also stall the engine. Both stall scenarios leave the rider without power mid-ride, which can reduce control and increase crash risk.
