Specs

One of the notable features of the GPZ900R was its four-cylinder inline engine with a liquid-cooled 16-valve double overhead cam (DOHC) configuration. This engine setup significantly differed from previous Kawasaki models and contributed to the bike’s impressive power and performance.

Furthermore, the GPZ900R gained recognition as the fastest production motorcycle upon its release. It’s top speed and acceleration capabilities set new standards in the industry and established Kawasaki as a leader in the super sports category.

The Kawasaki GPZ900R was a game-changer in the motorcycle industry, setting the stage for future advancements and inspiring the development of high-performance motorcycles that followed.

Technical Features 

  • Engine: The motorcycle has an inline four-cylinder engine with a total displacement of 908 cm³ (cubic centimetres). The machine has a quadruple butterfly system, which likely refers to the four throttle butterflies used for fuel-air mixture control. It is also assisted by four Mikuni carburettors, which mix fuel and air.
  • Valvetrain: The engine has 16 valves that are inclined at 35°. These valves are actuated by two overhead camshafts, which control the opening and closing of the valves. This configuration allows for efficient airflow and performance.
  • Power Output: The motorcycle produces 115 bhp (brake horsepower) or approximately 86 kW (kilowatts). This power enables the bike to reach speeds of 151 mph (243 km/h). Notably, it is mentioned that this motorcycle is the first production street bike to exceed 150 mph (240 km/h), indicating its performance capabilities.
  • Cooling System: The bike incorporates a water cooling system, which helps regulate the engine’s temperature. Combining water cooling with a 16-valve head likely improves heat dissipation, increasing power output.
  • Chassis Design: The motorcycle utilizes the engine as a load-bearing element. This design approach enhances the bike’s handling by improving rigidity and reducing weight. A stiffer chassis contributes to better control and manoeuvrability.
  • Anti-Dive Braking System: The motorcycle features an innovative braking system called “AVDS” (Automatic Variable Damping System), which helps prevent excessive front-end dive during braking. This system interacts with the braking system and ensures that the front fork does not compress excessively when weight is transferred to the front wheel. The bike maintains stability during deceleration by reducing the forward pitch caused by braking.
