Kawasaki Motors Demonstrates Hydrogen-Powered Motorcycle at the Suzuka Circuit

A groundbreaking hydrogen internal combustion engine (ICE)-powered motorcycle at the Suzuka Circuit marks a significant milestone in the company’s ongoing research and developments to create sustainable transportation for the future.

The showcased model, the Ninja H2, features a 998cc in-line four supercharged engine, modified to allow hydrogen injection directly into the cylinders. This innovative adaptation enables the engine to function similarly to conventional gasoline engines while emitting only water vapour and minor amounts of carbon dioxide, resulting from combusted engine oil.

Satoaki Ichi, Project Leader at Kawasaki, emphasised the engine’s conventional feel enhances the rider’s enjoyment by maintaining the traditional motorcycle experience. He also added “Hydrogen burns more quickly and under a wider range of conditions than gasoline, making it possible to create a more responsive feeling than ever,”

Kawasaki’s hydrogen ICE motorcycle, also known as the Ninja H2 SX-based prototype, is the first global hydrogen-powered motorcycle by a major manufacturer that is publicly demonstrated. This model incorporates significant changes to accommodate the hydrogen fuel system, including redesigned chassis and direct hydrogen injection modifications. Despite these changes, the bike retains its performance edge, with the supercharged engine traditionally producing 210bhp and 137Nm on the standard Ninja H2 SX.

The development of this motorcycle is part of Kawasaki’s broader commitment to achieving carbon neutrality and advancing sustainable transportation solutions. The company aims to introduce hydrogen ICE motorcycles by the early 2030s, offering an alternative to traditional fossil fuels.

Kawasaki’s efforts are supported by the Hydrogen Small Mobility & Engine Technology (HySE) association, a collaborative initiative that includes major Japanese manufacturers such as Honda, Yamaha, Suzuki, and Toyota. HySE focuses on research into hydrogen engines, filling systems, and fuel supply systems to support the development of small hydrogen-powered mobility vehicles.

At the Suzuki 8-hour endurance motorcycle race track, the Ninja H2 SX-based hydrogen ICE motorcycle is demonstrated, reinforcing the practical viability of hydrogen as a fuel source for high-performance motorcycles. The demonstration underscored the engine’s ability to produce a responsive and enjoyable riding experience while significantly reducing harmful emissions. Hydrogen combustion poses unique challenges and opportunities and Hydrogen burns much faster than gasoline across a broader temperature range, offering a more dynamic and responsive ride. However, the main byproduct is water vapour, emitted as moist air from the exhaust, which significantly reduces environmental impact.

Safety considerations are paramount in hydrogen technology. Kawasaki Motors ensures that its hydrogen-powered engines and fuel systems meet rigorous safety standards to prevent leaks and manage the inherent risks of hydrogen as a fuel. The development process includes extensive testing and validation to ensure both performance and safety are uncompromised.

Kawasaki’s vision extends beyond motorcycles to a broader hydrogen mobility initiative, reflecting its commitment to exploring all possibilities for sustainable transportation. This initiative aligns with global efforts to reduce carbon emissions and promote cleaner energy sources, positioning Kawasaki as a leader in the transition towards carbon-neutral mobility solutions.
