2023 Kawasaki Vulcan S Blends Sport Performance with Cruiser Comfort

Kawasaki motorcycles has been a dominant force in the motorcycle world, and its 2023 Vulcan S Sport Cruiser is another impressive addition to Kawasaki’s 2023 motorcycle lineup. This versatile bike is designed to cater to a wide range of riders, offering a comfortable ride with a unique style that combines the essence of both sportbikes and cruisers. At the heart of the 2023 Kawasaki Vulcan S is its powerful and reliable 649cc parallel-twin engine, which is derived from the popular Ninja 650. This fuel-injected, liquid-cooled engine provides ample torque and smooth power delivery, making this Japanese-made motorcycle suitable for both city riding and highway cruises.

The Vulcan S’s Ergo-Fit system sets it apart from its competition. This innovative feature allows riders to customize their seating position, footpeg placement, and handlebar reach. With a combination of adjustable components, the Ergo-Fit system ensures that riders of all sizes and preferences can find their perfect riding position.

The chassis of the 2023 Vulcan S features a high-tensile steel perimeter frame, providing a lightweight yet rigid foundation for the bike. The single-shock rear suspension is adjustable for preload, enabling riders to fine-tune their suspension setup.  Braking is handled by a 300mm front disc brake with twin piston calipers and a 250mm rear disc brake, both of which can be complemented by the ABS (Anti-lock Braking System).

The 2023 Kawasaki Vulcan S has a distinctive, modern look that sets it apart from traditional cruisers. Its angular bodywork and sharp lines give it an aggressive, sporty appearance. The stylish headlight, LED taillight, and minimalist instrumentation contribute to the bike’s contemporary aesthetic, making it a head-turner wherever it goes.  There is also a Cafe version with a stylish three-tone paint, a small windscreen and other visual updates.

2023 Kawasaki Vulcan S / S Cafe Features

Dual Throttle Valves

Late-model sport bikes often use large-bore throttle bodies to generate high levels of power. However, with large diameter throttles, when a rider suddenly opens the throttle, the unrestricted torque response can be strong. Dual throttle valve technology was designed to tame engine response while contributing to performance.

On models with dual throttle valves, there are two throttle valves per cylinder: in addition to the main valves, which are physically linked to the throttle grip and controlled by the rider, a second set of valves, opened and closed by the ECU, precisely regulates intake airflow to ensure a natural, linear response. With the air passing through the throttle bodies becoming smoother, combustion efficiency is improved and power is increased.

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.
