The 2023 Kawasaki Ninja 400 Is A Great Sportbike Entry

For 2023, Kawasaki has updated the Ninja 400 ABS which is designed for riders who are looking for a sleek and that can handle both city streets and winding roads while being accessible to newer riders. While the Ninja is powered by the smallest engine of Kawasaki’s Ninja family, the 399cc liquid-cooled, parallel-twin engine still delivers 45 horsepower and 28 lb-ft of torque and a nimble ride. The bike has a six-speed transmission and a slipper clutch, which makes downshifting smoother and easier. The Ninja 400 ABS also comes with a lightweight trellis frame, which improves the bike’s agility and handling. Bringing you to a stop on the Ninja 400 is the single 310mm front disc and a single 220mm rear which provide excellent stopping power and control. ABS is an extra cost add on which adds an extra layer of safety.

The Ninja 400 ABS also includes a digital instrument panel that displays speed, rpm, fuel level, and other information. The seat is designed to be comfortable for both riders and passengers, and the bike has a sleek and aerodynamic fairing that reduces wind resistance at high speeds. The baby ninja includes features that make it competitive with the other Japanese brands in the class and is an excellent choice for those entering the sportbike world.

2023 Kawasaki Ninja 400 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.
