To realise the goal of creating the ultimate motorcycle, help was enlisted from other companies in the Kawasaki Heavy Industries (KHI) Group, precipitating an unprecedented level of inter-company collaboration.

THE QUEST FOR POWER

Supercharged 998 cm³ In-Line Four

In-House-Designed Supercharger

The supercharger used in the Ninja H2R was designed by Kawasaki motorcycle engine designers with assistance from other companies within the KHI Group, namely the Gas Turbine & Machinery Company, Aerospace Company, and Corporate Technology Division. Designing the supercharger in-house allowed it to be developed to perfectly match the engine characteristics of the Ninja H2R. The highly efficient, motorcycle-specific supercharger was the key to achieving the maximum power and the intense acceleration that engineers wanted to offer.

Maximising Airflow Efficiency

Ram Air Intake

Air supplied to the supercharger enters via dual Ram Air intakes in the upper cowl. Their total frontal area is approximately 13,000 mm2—illustrating just how much air is needed to achieve the over 300 PS output.

The Ram Air duct was designed to route fresh air to the supercharger in as straight a line as possible. Its shape was derived to match the impeller characteristics, further contributing to the engine’s high output. The duct is constructed of highly rigid, lightweight CFRP (carbon-fibre reinforced polymer).

Keeping the Engine Cool

Oil Jets

To keep the engine compact and simple, a single lubrication system provides cooling oil for the engine components, supercharger and transmission. Oil jets lubricate the supercharger chain at the contact points where the chain meets the upper and lower gears. In addition, the supercharger drive train’s lower gear has an oil passage.

Inside the engine, there are two oil jets per cylinder to ensure the hot pistons are effectively cooled.

(Kawasaki Traction Control)

Kawasaki's most advanced traction control system offers a selection of mdoes to suit a variety of riding situations, from sport riding to touring

A mark appearing on the instrument panel to indicate favourable fuel consumption, encouraging fuel efficient riding.

Dual Injectors

Two injectors, operating at different rpm ranges, to deliver both quick response and increased high-rpm power.

Offering highly efficient braking while maintaining natural feel, this high-precision brake system was designed specifically for supersport models.
