2024 Kawasaki Ninja 125 Specs & Review

Kawasaki’s smallest Ninja brings big-bike styling and approachable performance to the 125 class. If you’re eyeing an A1-friendly sportbike for commuting, learning, or weekend twisties, the 2024 Kawasaki Ninja 125 specs show a well-rounded package with real-world usability and signature Ninja flair. In this Kawasaki Ninja 125 review, we break down the numbers that matter.

Key Specs at a Glance

  • Displacement: 125 cm³ (7.63 in³)
  • Engine type: Liquid-cooled, 4-stroke, single-cylinder; DOHC, 4 valves; compression ratio 11.7:1
  • Power: 11.0 kW (15 PS) at 10,000 rpm
  • Torque: 11.7 N•m (8.63 lb-ft) at 7,700 rpm
  • Kawasaki Ninja 125 weight: 149 kg (328.49 lbs) curb
  • Kawasaki Ninja 125 seat height: 785 mm (30.91 in)

Engine & Performance

The 125 cm³ single is liquid-cooled with a DOHC 4-valve head, delivering 11.0 kW (15 PS) at 10,000 rpm and 11.7 N•m at 7,700 rpm. That’s classic 125 performance—rev-happy and smooth—ideal for city slicing and confidence-building rides. Fuel injection (28 mm x 1) keeps response clean and predictable, while the digital ignition and electric start make everyday use painless.

A 6-speed, return-shift transmission paired with a wet, multi-disc clutch helps you keep the single in its sweet spot. The chain final drive is simple and efficient, and the gear spread supports both urban acceleration and relaxed cruising. Efficiency is a highlight: the Ninja claims 2.7 l/100 km (87.1 mpg), and CO₂ emissions are listed at 61 g/km—useful numbers for cost-conscious commuters who still want sporty looks.

Handling, Comfort & Kawasaki Ninja 125 Seat Height

The Kawasaki Ninja 125 seat height is 785 mm (30.91 in), making it accessible for a wide range of riders. Combined with the Kawasaki Ninja 125 weight of 149 kg (328.49 lbs) and a compact 1,330 mm wheelbase, low-speed maneuvering is easy and parking-lot confidence is high. The tubular diamond steel frame gives reassuring feedback, while a 90 mm trail and 35°/35° steering angle contribute to stability with nimble steering.

Suspension is straightforward and effective for its class: a 37 mm telescopic fork up front offers 110 mm of wheel travel, and a Uni-Trak, gas-charged rear shock with spring preload adjustability provides 120 mm of travel. This setup strikes a balance between comfort and control on city streets and flowing B-roads. Ground clearance is 170 mm, and the 17-inch wheel setup (100/80-17 front, 130/70-17 rear) delivers neutral, confidence-inspiring turn-in.

Equipment & Features

Braking hardware is a strong point for a 125: a single petal front disc of Ø 290 mm with a dual-piston caliper and a rear petal disc of Ø 220 mm, also with a dual-piston caliper. Petal rotors aid heat dissipation and look the part. Other notable elements from the 2024 Kawasaki Ninja 125 specs include:

  • Fuel injection and digital ignition for reliable starts and smooth fueling
  • Wet, multi-disc clutch for consistent engagement
  • Chain final drive with a final reduction ratio of 3.500 (56/16)
  • Practical 11.0 L fuel capacity for fewer stops

Who Is the 2024 Kawasaki Ninja 125 For?

This bike targets newer riders who want sporty styling with manageable performance, as well as experienced riders seeking a nimble, efficient commuter. Its accessible seat height, light curb mass, and user-friendly power delivery make it welcoming, while the 6-speed gearbox and responsive chassis keep it engaging for weekend fun. If you’re cross-shopping entry-level sportbikes, the Ninja 125’s blend of efficiency, handling, and style is compelling.

Torquepedia Verdict

The 2024 Ninja 125 nails the essentials: approachable performance, solid braking hardware, and a well-judged chassis. The engine’s 11.0 kW (15 PS) and 11.7 N•m figures deliver exactly what you want from a 125—smooth city pace and enough pep to enjoy twisty roads—while fuel consumption of 2.7 l/100 km (87.1 mpg) keeps running costs low.

On the flip side, riders seeking big midrange shove will naturally outgrow a 125 single. But judged in its class, the Ninja stands out with quality suspension components, petal discs, and a comfortable 785 mm seat height. If your checklist prioritizes efficient commuting, friendly ergonomics, and sharp Ninja styling, the Ninja 125 is a smart, confidence-inspiring pick.
