Technology Engine management

Ever since our first motorcycle engine in 1950, Kawasaki has been continually pursuing new technologies in the creation of our high-performance engines. Today, our models are filled with numerous original Kawasaki technological features that have evolved over our long history.

Supercharged engine

Designed completely in-house, the immense potential of the highly compact, highly efficient supercharged engine is a testament to the technology possessed by the KHI Group.

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.
