An affordable, beginner-friendly sport bike in Kawasaki's Ninja line, powered by a 248 cc liquid-cooled parallel twin with electric start and six gears. It was sold under several names, GPX250R and ZZR250 among them, and is known in later markets as the Ninja 250R. Its appeal was light weight, a low seat and gentle power rather than outright performance.
