Engine & Performance

At the heart of the H2 SX is a 998 cm³ in-line four with a factory supercharger, pairing a 76.0 mm x 55.0 mm bore and stroke with an 11.2:1 compression ratio. On paper, it makes 147.1 kW (197.3 hp) at 11,000 rpm and a stout 137.3 Nm (101.3 lb-ft) at 8,500 rpm; with Ram Air, output rises to 154.1 kW (206.6 hp). In the real world, that translates to effortless overtakes on the highway and a deep reserve of thrust when you’re having fun on a backroad.

Fuel injection with dual injectors (40 mm x 4) promotes precise fueling, while a digital ignition and forced-lubrication wet sump keep the supercharged four humming during sustained high-speed runs. A 6-speed return-shift transmission feeds a sealed chain with a 2.444 final reduction ratio, giving you a relaxed cruise in top gear yet instant response with a downshift. Despite the performance, Kawasaki quotes a frugal 5.4 l/100km fuel consumption and 128 g/km CO2 emissions, underscoring its sport-touring mission.

Handling, Comfort & Kawasaki Ninja H2 SX Seat Height

A trellis, high-tensile steel frame with a swingarm mounting plate provides rigidity and predictable feedback. Geometry is sport-touring stable with a 1480 mm wheelbase and 103 mm trail, while a 30° left/right steering angle helps low-speed U-turns. The 43 mm inverted fork offers compression and rebound damping plus spring preload adjustment (with top-out springs), and the rear Uni-Trak, gas-charged shock features a piggyback reservoir, high/low-speed compression and rebound adjustability, a remote spring preload adjuster, and a top-out spring. Wheel travel is a practical 120 mm front and 139 mm rear, striking a balance between support and comfort.

The Kawasaki Ninja H2 SX seat height is 835 mm (32.87 in), placing you up and over the tank with a neutral sport-touring stance. Taller riders will appreciate the roomy 2175 mm x 790 mm x 1260 mm overall dimensions, while shorter riders should test the reach and width. The Kawasaki Ninja H2 SX weight is 266 kg (586.4 lbs) curb, which you’ll feel during parking-lot maneuvers; once rolling, the chassis composure and 17-inch rubber—120/70 ZR17 front and 190/55 ZR17 rear—deliver planted confidence. Ground clearance is 130 mm, appropriate for brisk road riding without excessive compromise to comfort.

Equipment & Features

Braking is serious: dual semi-floating 320 mm front discs with radial-mount, monobloc, opposed 4-piston calipers and a 250 mm rear disc with a dual-piston caliper. The wet, multi-disc clutch and 6-speed gearbox support smooth transitions between steady-state touring and spirited runs. With a 19.0-litre (5.02 gal) fuel capacity, it’s ready for long stints between stops, complemented by the efficient 5.4 l/100km figure.

Details enthusiasts will notice include the sealed final chain, digital ignition, electric starting, and comprehensive suspension adjustability for tailoring ride quality to load or pace. Tyre sizes, wheel travel, and the adjustable fork/shock package add up to a road-biased setup capable of confident, fast touring.

Who Is the 2025 Kawasaki Ninja H2 SX For?

With nearly 200 hp on tap (and more with Ram Air) and a 266 kg curb mass, this is a machine best suited to experienced riders. It excels at fast cross-country work, two-up weekend escapes, and daily commuting where smooth power, stability, and comfort matter. New riders may find the combination of performance and size daunting, while seasoned sport-touring fans will appreciate the refinement, adjustability, and easy overtaking power.

Torquepedia Verdict

If you’re chasing supercharged excitement without abandoning comfort, the Ninja H2 SX delivers. The headline 197.3 hp and 137.3 Nm numbers, combined with a stable trellis chassis, quality brakes, and highly adjustable suspension, make it a formidable sport-tourer. The 19.0-litre tank and efficient 5.4 l/100km consumption support real-world touring, while the 998 cm³ engine’s seamless thrust turns every pass into a non-event.

On the flip side, the Kawasaki Ninja H2 SX weight and 835 mm seat height won’t suit everyone at low speeds, and shorter riders may want to consider fitment before committing. For riders who value long-distance capability with superbike punch, the 2025 Kawasaki Ninja H2 SX specs place it squarely among the most compelling choices in the class.
