Kawasaki has rebuilt the Ninja H2’s supercharged 998cc four-cylinder to meet Euro 5+
The Ninja H2 is back in Europe, and from the outside it looks almost unchanged. Underneath is another story. Kawasaki has reworked nearly every major part of the supercharged 998cc four-cylinder so it meets Euro 5+ emissions rules, which means the H2 can be sold in Europe again.
New Internals, Familiar Bodywork
The list of new engine parts is long. It includes the supercharger impeller, the whole intake system, the pistons, cylinder, cylinder head, crankshaft and camshafts. The throttle bodies are new and the gear ratios have changed.
The exhaust is new as well, with revised pipe diameters and a redesigned pre-chamber. The polished twin-outlet can has gone, replaced by a compact single-exit silencer. Kawasaki says the lighter system adds torque in the low and mid-range.
Less Peak Power, by Design
Output is 209hp (154kW) at 11,000rpm, measured with ram air. Peak torque is 135Nm at 8,500rpm. When the H2 was last homologated in the US, it was listed at 228hp, so on paper the new bike has less power.
Kawasaki says it wanted more mid-range strength while keeping the H2’s familiar surge at high revs. That is the company’s stated goal, and no independent riding impressions are available yet. Weight is unchanged at 238kg ready to ride.
A Shared Heart With the H2 SX?
This is where it gets interesting. The new H2 has the same 76 x 55mm bore and stroke as the 2026 H2 SX sport tourer. It also makes peak power and peak torque at exactly the same revs. The single-outlet exhaust already appears on the H2 SX and the Z H2, and both have met the stricter rules all along.
Kawasaki has not confirmed a shared base or commented on the overlap. Still, the parallels are hard to ignore.
Brakes, Chassis and Electronics
The H2 is the first Kawasaki to use Brembo Hypure four-piston calipers, which replace the Stylema units. They clamp 330mm semi-floating discs. The trellis frame stays, along with a 43mm KYB AOS-II fork, an Öhlins TTX36 shock and an electronic Öhlins steering damper.
A new dash offers two layouts. One places supercharger readings at its centre and shows lean angle in an aviation-style graphic. Nice. The traction and launch control systems have been reworked, and the bike keeps cornering ABS, a two-way quickshifter and cruise control.
