Kawasaki’s liter-class supersport is built for riders who want track-bred precision without sacrificing road manners. If you’re comparing modern inline-four superbikes, the 2025 Kawasaki Ninja ZX-10R specs deliver the numbers and hardware that matter. In this Kawasaki Ninja ZX-10R review, we explain how those figures translate to the ride.

Engine & Performance

The 998 cm³ DOHC inline-four is the heart of the ZX-10R’s identity. Peak output is 149.3 kW (203 PS) at 13,200 rpm, rising to 156.8 kW (213 PS) with RAM Air at the same rpm, backed by 114.9 N•m (84.7 lb-ft) at 11,400 rpm. That means a bike that builds speed relentlessly above midrange, with a top-end howl that rewards riders who are comfortable working the upper revs.

Fuel injection uses dual injectors (47 mm x 4) for crisp throttle response, while a 13.0:1 compression ratio and digital ignition keep the engine sharp and eager. On the street, this translates into a clean, predictable roll-on in higher gears and tractable response out of corners. On the highway, Kawasaki claims 6.0 l/100km (39.2 mpg), which is respectable for a superbike of this output.

A 6-speed, return-shift cassette transmission is paired with a wet, multi-disc clutch and sealed chain final drive. The cassette design isn’t just race-bred for quick ratio swaps; it also helps with maintenance and track-focused setup. Primary and final reduction ratios (1.681 and 2.412) combine with the listed gear ratios to deliver strong drive without feeling abrupt.

Handling, Comfort & Kawasaki Ninja ZX-10R Seat Height

The chassis is a twin spar cast aluminium frame with geometry aimed at stability and precision. A 1,450 mm wheelbase and 105 mm trail keep the ZX-10R planted through fast sweepers, while a 27° steering angle (L/R) aids low-speed maneuvering. OEM tire fitment is 120/70 ZR17 front and 190/55 ZR17 rear—aggressive yet versatile sizes that suit both track rubber and grippy road compounds.

Kawasaki Ninja ZX-10R seat height is 835 mm (32.87 in). Combined with a 207 kg (456 lb) curb mass, shorter riders may find tiptoeing necessary, especially on uneven surfaces. Taller riders will appreciate the roomy cockpit and the leverage it provides. Ground clearance is 135 mm, and wheel travel is 120 mm front / 115 mm rear—enough for compliance on rougher roads while keeping the bike taut for track days.

Dimensions of 2,085 mm (L), 750 mm (W), and 1,185 mm (H) give the ZX-10R a compact frontal area, aiding aerodynamics and lane filtering. The net result is a literbike that feels composed in fast sections and precise on turn-in, with predictable behavior at commuting speeds once you’re comfortable with the height and weight.

Who Is the 2025 Kawasaki Ninja ZX-10R For?

This bike suits experienced riders who want a focused supersport for weekend blasts and track days without giving up road usability. The strong top-end power and adjustable suspension reward skilled inputs and setup time. For daily commuting, the smooth fueling and reasonable economy help, though the 835 mm seat height and 207 kg curb mass will be more comfortable for confident, taller riders.

New riders should look elsewhere; the combination of 998 cm³ displacement and 203 PS demands restraint and experience. If value matters, note the MSRP figures provided: $17,799 (US) and €20,695 (EU).

Torquepedia Verdict

The 2025 Kawasaki Ninja ZX-10R specs read like a purist’s checklist: a high-revving inline-four with up to 213 PS (with RAM Air), fully adjustable race-derived suspension, and serious Brembo hardware. On the road, it’s predictably composed, with clean fueling and a chassis that encourages committed cornering.

Its weaknesses are the inherent demands of a liter-class supersport: a tall 835 mm seat height and a curb mass of 207 kg that can feel substantial in stop-and-go traffic. If your priority is track-capable performance with proven hardware, the ZX-10R remains a compelling pick in the class.
