Kawasaki’s legendary supercharged Ninja H2 is getting an update for 2027, and the news comes with a caveat that’s got the internet buzzing. Fresh EPA and CARB filings reveal that the new generation might be losing more than thirty horsepower compared to the current model. That’s a significant drop for a bike positioned as the engineering pinnacle of Kawasaki’s lineup.
The 2026 Ninja H2 was certified at 228 hp at 11,500 rpm. The 2027 version, according to homologation documents, will share emissions data with the Z H2 SE, pointing to a new peak of 197 hp at 10,500 rpm. The change appears to stem from production simplification rather than pure emissions compliance, aligning the supercharged engine across both Ninja and Z model lines. That said, 197 hp is still plenty of performance for a street bike.

Why Less Power Might Actually Be Fine
Yes, 31 fewer horses sounds like a punch to the gut. But here’s the thing: peak power numbers don’t tell the whole story. The Suzuki Hayabusa proved this when it came back with 190 hp instead of its original 197, and real-world testing showed it was just as quick where it mattered. Same engine, different tune, different era of emissions rules. The H2 has been gradually tightening its grip on its own position in the market, and if losing some headline figures means Kawasaki can keep building these bikes profitably, that’s a trade worth considering.
Interestingly, 197 hp is the exact output the first-generation Ninja H2 launched with back in 2015. Kawasaki is essentially cycling back to where it started, though with over a decade of refinement and technology improvements under the belt. The new homologation codes (ZXT02W for the standard H2, ZXT02X for the Carbon) suggest this is a different generation despite the power alignment, so we should expect updates beyond just engine tuning.

The UK Angle: Maybe Not Coming at All
There’s a wrinkle here for riders across the Atlantic. Last year, Kawasaki announced it would stop taking new orders for road-going Ninja H2 and H2 Carbon models, making the 2026 edition the final for the European market. These EPA and CARB filings point to U.S. availability in 2027, but there’s no guarantee it’ll make the trip to the UK or Europe. For now, these documents are intriguing hints of what could have been, at least in some markets.
Kawasaki clearly sees a future for its supercharged flagship somewhere in the world. Whether that translates into a bike you can actually walk into a dealership and buy depends on which side of the Atlantic you’re on. Either way, if these filings are accurate, the 2027 Ninja H2 will still be a serious piece of machinery. Just with slightly less bragging rights on the dyno.
