The 2023 Kawasaki Z400 Packs A Lot In A Small Package

The 2023 Kawasaki Z400 ABS is one of several naked options from the Kawasaki motorcycle brand.  This new rider friendly naked motorcycle packs a punch in a lightweight package. While not the smallest in Kawasaki’s long list of 2023 bike model, the heart of the Z400 is a 399cc liquid-cooled engine that still delivers impressive performance while producing 44 horsepower and 25 lb-ft of torque.  Kawasaki didn’t skimp on features with this small bike and it features an Assist & Slipper Clutch which helps to provide smooth shifting and prevents wheel hop during aggressive downshifts.  With its sleek design and advanced technology, this bike is geared for riders who are looking for a high-performance motorcycle that is both fun to ride and easy to handle.

One impressive feature of the Z400 is its lightweight chassis. Weighing in at just 363 lbs, this bike is incredibly nimble and easy to handle, making it ideal for riders of all skill levels.  Another key feature of the Z400 ABS is its advanced technology. This bike comes equipped with a full digital instrumentation that includes a tachometer, speedometer, odometer, trip meter, fuel gauge, and more.   The Z400 ABS obviously includes safety features such as Anti-lock Brakes (ABS) as standard, which helps to prevent the wheels from locking up during sudden stops, reducing the risk of skidding and accidents.  In this crowded class of small displacement Japanese bikes, Kawasaki definitely has a contender in the Z400 ABS.

The 2023 Kawasaki Z400 starts at: $5,399 USD/$6,699 CAD

2023 Kawasaki Z400 Features

Assist & Slipper Clutch

Based on feedback from racing activities, the Assist & Slipper Clutch uses two types of cams (an assist cam and a slipper cam) to either drive the clutch hub and operating plate together or apart.
Under normal operation, the assist cam functions as a self-servo mechanism, pulling the clutch hub and operating plate together to compress the clutch plates. This allows the total clutch spring load to be reduced, resulting in a lighter clutch lever feel when operating the clutch.
When excessive engine braking occurs – as a result of quick downshifts (or an accidental downshift) – the slipper cam comes into play, forcing the clutch hub and operating plate apart. This relieves pressure on the clutch plates to reduce back-torque and helps prevent the rear tire from hopping and skidding. This race-style function is particularly useful when sport or track riding.

Economical Riding Indicator

Using high-precision electronic control for engine management, Kawasaki models can achieve a high level of fuel efficiency. However, fuel consumption is greatly affected by throttle use, gear selection, and other elements under the rider’s control. The Economical Riding Indicator is a function that indicates when current riding conditions are consuming a low amount of fuel. The system continuously monitors fuel consumption, regardless of vehicle speed, engine speed, throttle position and other riding conditions. When fuel consumption is low for a given speed (i.e. fuel efficiency is high), an “ECO” mark appears on the instrument panel’s LCD screen. By riding so that the “ECO” mark remains on, fuel consumption can be reduced.

While effective vehicle speed and engine speed may vary by model, paying attention to conditions that cause the “ECO” mark to appear can help riders improve their fuel efficiency – a handy way to increase cruising range. Further, keeping fuel consumption low also helps minimize negative impact on the environment.

ABS (Anti-lock Brake System)

Kawasaki ABS systems use front and rear wheel sensors to constantly monitor wheel speed. Should information from either of the sensors indicate that wheel lock has occurred, the ABS ECU directs the pump in the ABS unit to modulate brake fluid pressure (releasing and reapplying pressure so that traction can be regained) until normal operation resumes. ABS offers rider reassurance that contributes to greater riding enjoyment.


Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style.

ERGO-FIT is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride.

*Adjustable parts and their range of adjustability vary by model.
