The 2021 Kawasaki Vulcan S and Vulcan S Cafe models are a very interesting take on a sports cruiser. Whereas most cruisers, including in Kawasaki’s own lineup, are powered by V-twins, the Vulcan S uses the very same 649cc parallel-twin that is found in the Ninja 650 and Z650 sport bikes. For the cruiser, however, the engine gains a heavier flywheel and a different routing of the air intake to give the plucky little motor some serious down low grunt and mid-range power. In fact, it develops 54 HP and 46 lb-ft of torque, with most of that torque starting to come in at 3,000 RPM.

In an attempt to make this a friendly cruiser for everyone, the Japanese manufacturer designed their patented Ergo-Fit system, which allows three different peg positions, three different seat types, and three different handlebar angles you can choose. As well, compared to 2020, dual-zone ABS has become standard across all Vulcan models, globally.

There is also an S Cafe variant of the Vulcan, which adds a Cafe Racer style cowling and low wind deflector around the front headlight. It also gains a cafe inspired three tone paint option, but otherwise remains the same specification as the base Vulcan S.

The 2021 Kawasaki Vulcan S starts at $7,599 USD / $8,499 CAD, while the Vulcan S Cafe starts at $8,199 USD / $8,899 CAD.

2021 Kawasaki Vulcan S/S Cafe Features

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.

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.

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.
