The 2006 Kawasaki Ninja ZX-14 has two recalls, the more serious being a frame weld that can crack and cause the rear suspension to collapse while riding, which can result in a crash.
The frame issue involves the lower rear crossmember, where over-tightened engine mount collars place stress on the surrounding welds until they crack, leaving the rear suspension with no structural support. The second recall involves the vehicle down sensor, which may not have been properly secured during assembly. This sensor detects when the motorcycle has fallen over, and a loose or failed sensor can interfere with the engine's ability to start or run correctly.
