The launching point for the development of the Ninja H2R was a strong desire to offer riders something they had never before experienced. The bike needed to deliver intense acceleration and an ultra-high top speed, coupled with supersport-level circuit performance. The H2R has fully encapsulated what it is like to ride a Kawasaki Ninja.

Drawing on the know-how and technology possessed by the KHI Group, Kawasaki’s supercharged engine delivers high engine output while maintaining a compact design. The key to achieving this incredible performance lies in the engine’s supercharger – a motorcycle-specific unit designed completely in-house with technology from Kawasaki’s Gas Turbine & Machinery Company, Aerospace Company and Corporate Technology Division.
One of the greatest benefits of designing the supercharger in-house and tailoring its design to match the engine’s characteristics was that engineers were able to achieve high-efficiency operation over a wide range of conditions – something that would not have been possible by simply dropping in or trying to adapt an aftermarket automotive supercharger.
The importance of high efficiency in a supercharger is that, as the air is compressed, power-robbing heat gain is minimal. And while many superchargers are able to offer high-efficiency operation in a very limited range of conditions, Kawasaki’s supercharger offers high efficiency over a wide range of pressure ratios and flow rates – meaning over a wide range of engine speeds and vehicle speeds. This wide range of efficient operation (similar to having a wide power band) easily translates to strong acceleration. The supercharger’s high efficiency and minimal heat gain also meant that an intercooler was unnecessary, greatly saving weight and space, and enabling the engine’s compact design.
Kawasaki Engine Brake Control
The Kawasaki Engine Brake Control system allows riders to select the amount of engine braking they prefer. When the system is activated, the engine braking effect is reduced, providing less interference when riding on the circuit.
Electronic Throttle Valves
Kawasaki’s fully electronic throttle actuation system enables the ECU to control the volume of both the fuel (via fuel injectors) and the air (via throttle valves) delivered to the engine. Ideal fuel injection and throttle valve position results in smooth, natural engine response and the ideal engine output. The system also makes a significant contribution to reduced emissions.
Electronic throttle valves also enable more precise control of electronic engine management systems like S-KTRC and KTRC, and allow the implementation of electronic systems like KLCM, Kawasaki Engine Brake Control, and Cruise Control.
Kawasaki’s high-quality original paint has a highly reflective, glasslike metal appearance. Its debut on the 2015 Ninja H2 and Ninja H2R marked its first use on a mass-production vehicle in either the automotive or motorcycle industries.
In the shade the paint has the appearance of its base coat colour, but once in the sunlight its highly reflective surface takes on the appearance of the surrounding scenery. The stark difference in the way the paint appears in the light and the shade emphasises the sculpted shape of the bodywork on which it is applied.
The highly reflective surface is created by inducing a silver mirror reaction (a chemical reaction between a solution of silver ions and a reducing agent) that forms a layer of pure silver (Ag). This Ag layer is what creates the paint’s glasslike metal appearance. Compared to candy paints, which use aluminium flakes to generate a sparkling effect, the Ag layer appears as a uniform metallic surface.
In the shade the Ag layer is translucent, allowing the base coat colour to show through. This gives the paint a deep, three-dimensional quality.
While the multiple layers of paint on typical mass-production models are done by robot painters, for this silver-mirror paint each layer – from primer to clear coat – is carefully finished by the hands of Kawasaki craftsmen to ensure a flawless, lustrous surface.
KQS: Kawasaki Quick Shifter
Designed to help riders maximise their acceleration on the circuit by enabling clutchless upshifts with the throttle fully open, KQS detects that the shift lever has been actuated and sends a signal to the ECU to cut ignition so that the next gear can be engaged without having to use the clutch. For some models, when a race kit ECU is used, clutchless downshifts are also possible.
