The Kawasaki GPZ900R (also known as the ZX900A or Ninja 900) is a motorcycle that was manufactured by Kawasaki from 1984 to 2003. It is the earliest member of the Ninja family of sport bikes. The 1984 GPZ900R (or ZX900A-1) was a revolutionary design[1][3] that became the immediate predecessor of the modern-day sport bike.[5] Developed in secret over six years, it was Kawasaki's and the world's first 16-valve liquid-cooled inline four-cylinder motorcycle engine.[3][7][8]
The 908 cc four-cylinder engine delivered 115 bhp (86 kW), allowing the bike to reach speeds of 151 mph (243 km/h), making it the first stock road bike to exceed 150 mph (240 km/h).[3]
Prior to its design, Kawasaki envisioned producing a sub-liter engine that would be the successor to the Z1.[3] Although its steel frame, 16-inch front and 18-inch rear wheels, air suspension, and anti-dive forks were fairly standard at that time, the narrow, compact engine[5] was mounted lower in the frame, allowing it to take Japanese superbike performance to a new level.[3] Six months after being unveiled to the press in December 1983, dealers entered three works GPZ900R bikes in the Isle of Man Production TT finishing in first and second places.[3][5][9][10]
