Kawasaki’s supercharged naked returns as a brawny, tech-forward streetfighter built for riders who crave big torque and brutal acceleration without fairings. In this Kawasaki Z H2 review, we break down the 2025 Kawasaki Z H2 specs that matter to aggressive commuters and weekend canyon hunters alike.
At the heart of the Z H2 is a 998 cm³, liquid-cooled, DOHC 16-valve inline-four with a factory supercharger. The headline figures—147.1 kW {200 PS} at 11,000 rpm and 137.0 N•m at 8,500 rpm—translate to fierce roll-on power and immediate thrust when you crack the throttle. Peak torque arriving well before redline means city slicing is just as entertaining as highway blasts, and the characteristic supercharged shove makes short work of overtakes.
Fueling comes via 40 mm x 4 injectors paired to a digital ignition system, helping deliver smooth response. A 6-speed, return-shift gearbox feeds a sealed chain final drive, keeping things straightforward and robust for daily use. Despite the performance, the Z H2 returns a listed fuel consumption of 6.0 l/100km (39.2 mpg) and CO2 emissions of 134 g/km, solid numbers for a machine with this level of output. For long days, a 19.0 litres / 5.02 gal fuel capacity helps extend your fun between stops.
The trellis, high-tensile steel frame anchors the chassis with a measured blend of rigidity and feel. Stability is aided by a 1,455 mm / 57.28 in wheelbase and 104 mm / 4.09 in trail, making the bike planted during high-speed runs while remaining manageable in urban cut-and-thrust. The Kawasaki Z H2 seat height is 830 mm / 32.68 in, which will suit average-to-taller riders; shorter riders may want to try before buying to assess reach and low-speed confidence.
The Kawasaki Z H2 weight (curb mass) is 239 kg / 527 lbs. You feel that bulk when maneuvering at walking pace, but once rolling, the chassis geometry and suspension support quick direction changes. Ground clearance is 140 mm / 5.51 in, and steering angle is a practical 29° to both sides, helping tight U-turns and garage shuffles.
Stopping power is a highlight: dual 320 mm semi-floating front discs clamped by Brembo radial-mount M4.32 monobloc, opposed 4‑piston calipers. Out back, a 260 mm single disc with a single-piston caliper handles stabilization and low-speed braking. The setup offers strong bite and consistent feel suited to the Z H2’s power.
Suspension is track-capable yet street-honest. Up front, an inverted Separate Function fork (SFF-BP) provides adjustable compression, rebound, and spring preload; rear duties are handled by a Uni-Trak, gas‑charged shock with adjustable rebound damping and spring preload. Wheel travel is 120 mm / 4.72 in front and 134 mm / 5.28 in rear—enough to keep the ride composed over imperfect pavement without dulling feedback.
The chassis rides on 17-inch rubber: 120/70 ZR17 (58W) front and 190/55 ZR17 (75W) rear, a proven combo for grip and agility. Additional details enthusiasts will appreciate include an electric starting system, wet multi-disc clutch, and a sealed chain final drive. Practical touches: a 19.0 litres / 5.02 gal tank and dimensions of L: 2,085 mm / 82.09 in, W: 810 mm / 31.89 in, H: 1,130 mm / 44.49 in.
With 200 PS on tap and a supercharged character, the Z H2 is aimed squarely at experienced riders who want superbike-level thrust in a naked package. It can commute thanks to its manageable seat height and fueling, then flip into weekend fun mode without breaking a sweat. Beginners will be better served by smaller, lighter machines before stepping into this league.
The 2025 Kawasaki Z H2 specs paint a clear picture: outrageous power, serious brakes, and quality suspension inside a stable, confidence-inspiring chassis. The supercharged engine is the star, delivering addictive midrange and top-end push without drama when ridden responsibly.
Trade-offs? The Kawasaki Z H2 weight of 239 kg and the 830 mm seat height may intimidate smaller riders at a standstill, and its performance focus rewards smooth inputs. But if you want a hyper-naked that blends everyday usability with headline-grabbing performance, the Z H2 sits right near the front of the pack.
