Engine & Performance

If your benchmark is sheer thrust, the 2025 Kawasaki H2R specs are staggering. The 4-cylinder, 998 cc engine makes a claimed 228.0 kW {310 PS} at 14,000 rpm, rising to 240.0 kW {326 PS} with RAM Air at the same revs. Peak torque is 165.0 N•m {16.8 kgf•m} at 12,500 rpm (121.7 lb-ft), signaling a motor that loves to spin and rewards riders who keep it in the upper rev range.

Around town, the 6-speed return-shift gearbox helps keep the engine in its sweet spot without constant hunting for gears. On fast roads and closed-course riding, the tightly stacked ratios (1st: 3.188 through 6th: 1.348) and a primary reduction of 1.551 with a final reduction of 2.333 deliver relentless drive. A sealed chain final drive supports durability under high loads. In practice, this translates to instant, linear acceleration once you’re past midrange, with a top-end that feels almost bottomless.

Handling, Comfort & Kawasaki H2R Seat Height

The Kawasaki H2R seat height is 830 mm (32.68 in), placing the rider in a purposeful, commanding position typical of elite sport machines. For taller riders, this offers room to move and weight the pegs; shorter riders may find the reach manageable but will need to account for the 216 kg (476.2 lbs) curb mass at parking-lot speeds.

Chassis geometry skews toward high-speed stability and precise cornering: a 1,450 mm wheelbase, 108 mm (4.25 in) trail, and steering angles of 27° left and right combine for confident turn-in while maintaining composure on the gas. Ground clearance is 130 mm (5.12 in), and wheel travel measures 120 mm (front) and 135 mm (rear)—enough to keep the bike settled over curbing and imperfect surfaces without dulling feedback.

Tire fitment is aggressive: 120/600 R17 up front and 190/650 R17 at the rear, providing a substantial contact patch and support during high-load cornering. The Kawasaki H2R weight is well-managed by the trellis, high-tensile steel frame, which communicates track-focused rigidity with predictable flex characteristics.

Equipment & Features

Braking hardware is top-shelf. Up front are dual semi-floating Brembo discs (Ø 330 mm) clamped by Brembo radial-mount, Stylema monobloc opposed 4-piston calipers—designed for strong initial bite, consistent modulation, and heat management. The rear setup is a single 250 mm disc with a Brembo opposed dual-piston caliper for controlled trail braking and stability.

Suspension is equally serious. The front uses a Ø 43 mm inverted fork with compression and rebound damping plus spring preload adjustability and top-out springs. Out back, a Uni-Trak linkage works with an Öhlins TTX36 gas-charged shock with piggyback reservoir, offering compression and rebound damping, spring preload adjustability, and a top-out spring—track-ready support with tuning range for different riders and circuits.

Electronics and rider aids are not listed in the provided specifications; focus here is clearly on mechanical excellence.

Who Is the 2025 Kawasaki H2R For?

Given the 2025 Kawasaki H2R specs, this machine is best suited to experienced riders who can exploit its high-rpm power delivery and chassis fidelity. It thrives on fast roads and closed-course environments where the engine can breathe at 12,000 rpm and beyond. Beginners will find the combination of 228.0 kW {310 PS}, a tall-ish 830 mm seat, and a 216 kg curb mass overwhelming. For commuting, its mission-focused setup is overkill; for weekend blasts and dedicated performance riding, it’s in its element.

Torquepedia Verdict

The 2025 H2R delivers an uncompromising performance package: colossal peak output, a communicative trellis chassis, adjustable high-spec suspension, and Brembo Stylema stopping power. The synergy between a rev-happy 998 cc four and a precise 6-speed gearbox makes it intoxicating when ridden hard.

Trade-offs? The Kawasaki H2R weight and seat height demand confidence at low speeds, and the bike’s personality is unapologetically focused on high-performance riding rather than everyday practicality. If your priority is the most extreme expression of a liter-class hyper-sport with componentry to match, the H2R sits at the sharp end of the segment.
