The Kawasaki Ninja H2 Supercharged was discontinued primarily due to its non-compliance with the newer Euro 5 plus emission regulations. Introduced in 2015 and last updated in 2019 with minor tuning and emission adjustments, the bike did not receive further updates to meet the stricter Euro 5 plus standards that came into effect in 2025. This, combined with the lack of significant technological advancements over its nearly 10-year lifespan, led Kawasaki to discontinue the model as they updated their other sport bikes to comply with the new regulations.
