Engine & Performance

At the heart of the 2023 Kawasaki Z400 specs is a 399 cm³ parallel twin with DOHC and 8 valves. It’s tuned for a broad, approachable spread of performance: 33.4 kW (45 PS) arrives at 10,000 rpm, so there’s genuine top-end zing when you wring it out, and 37.0 N•m (27.3 lb-ft) at 8,000 rpm gives a healthy midrange for slicing through city traffic or powering out of corners.

Fuel injection (32 mm x 2) and a digital ignition system keep throttle response crisp and predictable. Paired with a 6-speed return-shift gearbox and a wet, multi-disc clutch, gear changes are light and precise. The final drive is a sealed chain—simple, efficient, and easy to maintain. For daily duty, the Z400’s efficiency stands out: fuel consumption is rated at 3.9 l/100km (60.31 mpg), and CO2 emissions are listed at 91 g/km. It fires up via an electric starter and uses forced lubrication with a semi‑dry sump for dependable durability.

On the road, the engine’s character makes sense: docile enough for learners yet lively enough to reward more aggressive riding. It’s happiest being revved, but the torque curve remains friendly for short-shifting through town.

Handling, Comfort & Kawasaki Z400 Seat Height

The Z400 rides on a trellis, high-tensile steel frame, a recipe that keeps things light and communicative. Geometry is well-judged for real-world riding: a 1,370 mm (53.94 in) wheelbase and 92 mm (3.62 in) trail balance agility with stability. A generous left/right steering angle of 35° helps with tight U-turns and parking-lot maneuvers—handy for urban riders.

Suspension consists of a 41 mm telescopic fork up front and a Bottom-link Uni-Trak, gas-charged shock at the rear with spring preload adjustability. Wheel travel is 120 mm (4.72 in) front and 130 mm (5.12 in) rear, enough to smooth out rough pavement while keeping feedback sharp. The tire sizes—110/70R17 (front) and 150/60R17 (rear)—offer quick turn-in and confidence on corner exits without sacrificing stability.

The Kawasaki Z400 seat height is 785 mm (30.91 in), an accessible figure that pairs well with the bike’s 167 kg (368.17 lbs) curb mass. Shorter riders will appreciate how easy it is to get boots on the ground, while taller riders still have room to breathe thanks to the neutral naked-bike ergonomics. Ground clearance is 145 mm (5.71 in), and overall dimensions (L: 1,990 mm, W: 800 mm, H: 1,055 mm) keep it compact for commuting and filtering.

Equipment & Features

Braking hardware is straightforward and effective: a single semi-floating petal disc up front (Ø 310 mm) with a dual-piston caliper, and a single petal disc at the rear (Ø 220 mm) with a dual-piston caliper. The petal design helps with heat dissipation during spirited rides or repeated stops in traffic.

The front suspension’s 41 mm fork provides solid support under braking, while the rear Uni-Trak shock’s gas charge and preload adjustability let riders fine-tune for load or preference. A 14.0-litre (3.70 gal) fuel capacity supports commuting and weekend blasts without constant fuel stops. Other mechanicals include a primary reduction ratio of 2.219 (71/32), well-spaced gear ratios for the 6-speed transmission, and a final reduction ratio of 2.929 (41/14).
