• Liquid-Cooled, 16-Valve Engine: The heart of the Ninja was its 908cc inline-four engine. Liquid cooling allowed for tighter tolerances and higher compression, resulting in more power. The 16-valve design (four valves per cylinder) was cutting-edge for its time, improving breathing and further boosting performance.
• Compact Engine Design: The engine was designed to be as compact as possible, allowing for a shorter wheelbase and improved handling. This was crucial for the bike's sporty character.
• Perimeter Frame: The GPZ900R used a perimeter frame, where the frame rails ran around the outside of the engine. This design provided superior rigidity compared to traditional frames, enhancing handling and stability.
• Aerodynamic Fairing: The GPZ900R was one of the first motorcycles to feature a full fairing designed for aerodynamic efficiency. This not only improved top speed but also enhanced rider comfort by reducing wind blast.
