Kawasaki VN 650 Vulcan S

The Vulcan® S has the same low silhouette of a bigger-bore Vulcan® cruiser, mixed with Kawasaki Ninja®-derived power and handling, as well as its popular ERGO-FIT™ sizing system, designed to comfortably fit a wide range of riders. From 2020, the Kawasaki Vulcan S cruiser returns with Kawasaki’s user-friendly and unique ERGO-FIT with a total of 18 combination adjustments by adjusting the motorcycle’s seat, footpegs and handlebar. This allows for three seat options for added comfort and rider placement, three footpeg placement options, and two different reach handlebars.

With its unique engine, frame, suspension and non-traditional cruiser looks, the Vulcan® S was designed to be different. It was also designed to provide a high level of fit and comfort to help inspire a confidence in riding that makes the Vulcan® S especially attractive to new riders.

The Vulcan S is not your average cruiser. It stands apart, with its Parallel Twin engine, unique frame and suspension layout, and its very non-traditional looks. Unlike any other cruiser, the Vulcan S is geared to fit a wide range of riders. Never taking away from its stylish features, this bike takes comfort, adjustability, and Ninja®-derived power and performance to the next level.

Furthermore, the Vulcan S boasts one of the lowest weights of any motorcycle in its class (twin cylinder cruiser of similar displacement) and we all know what that means–easier to maneuver, quicker acceleration, easier to stop, quicker to turn and smooth suspension action.

Unlike any other cruiser, the Vulcan® S is designed to transport riders into a sporty realm in edgy style. Blending an aggressive ride with a vintage styling and a powerful 649cc engine, this bike kicks any experience into high gear. Whether you’re commuting to work or enjoying a day trip, the Vulcan S adds confidence-inspiring performance to every ride.

ENGINE

Liquid-cooled, DOHC, 8-valve 649cc parallel twin with fuel injection delivers smooth, responsive performance, especially in the low and medium rpm ranges. The Ninja® 650-based engine is re- tuned for even more rider-friendly power characteristics that will inspire confidence in new riders. The Vulcan S offers smooth starts from a standstill, smooth acceleration, and a satisfying pull when accelerating. The strong acceleration helps with highway merging and passing.

Intake porting, camshaft profiles and long-type intake funnels contribute to strong low-mid rpm performance, contributing to the smooth acceleration and good pull feeling.
Crankshaft design includes a heavier flywheel mass than the Ninja 650. This contributes to the easy-to-use engine character so it is very smooth when rolling on and off the throttle which makes pulling away from a stop easier.
Connector tube joining the header pipes helps eliminate peaks and valleys in the torque curve, resulting in smoother power delivery.
The design of the under-engine muffler contributes to strong torque in the low-mid rpm range wich helps with control at lower engine speeds.
Parallel twin engine is compact and helps reduce the dimensions of the entire motorcycle to keep it small and nimble.
180-degree crankshaft plus balancer shaft for extremely smooth engine operation.
Triangular crank and transmission shaft layout makes the engine very short from front to back, a semi-dry sump(KP) oil system reduces overall engine height, while the narrow pitch of the chrome composite(KP) plated aluminum cylinders helps reduce engine width.

Positive Neutral Finder(KP)

Just lift the shift pedal from first gear at a stop to select neutral easily.
A Kawasaki exclusive.

Digital Fuel Injection (KP)

Fuel injection settings provide smooth low end response while contributing to the engine‘s quick- revving character.
Dual 38mm Keihin throttle bodies feature sub-throttle valves(KP) for high power output with smooth, sensitive throttle response. The sub throttles, located behind the main throttle valves, are controlled by the ECU so that the EFI system has smooth throttle response.
Precise fuel injection plus exhaust catalyzer significantly reduce emissions.
Fine-atomizing fuel injectors produce a fine fuel mist for better acceleration, combustion and fuel consumption.

The chassis is slim and lightweight, due in part to the compact design of the engine. Light, easy handling is complemented by a reassuring low seat height and a slim design that makes it easy to reach the ground. The low overall weight is apparent as the bike is lifted off its side stand, making the Vulcan S one of the most accommodating bikes for new riders available.

Frame

The compact engine allows use of a slim, minimalist frame, resulting in a design that is narrow at the knees and feet.
3D analysis was used to achieve the ideal stiffness balance for the frame, contributing to superb handling characteristics.
Constructed of high-tensile steel for strength and light weight.
The layout of the offset single-shock rear suspension allows the battery to be located beside the shock instead of beneath it. This elegant arrangement allows a lower seat height as well as a slim design.
The exhaust is kept under the engine as much as possible, ensuring a slim chassis and an unobstructed reach to the ground.
The Vulcan S’s low weight and low center of gravity make it highly maneuverable, whether riding, pushing from a parking spot, or walking beside the bike.
Slim backbone-style rear frame design allows all components to be positioned close to the bike centerline.
Instead of using seat rails, a single beam formed from interlocked C-section pieces is used. The slim design enables a more comfortable seat construction.
Separate swingarm pivot plates contribute to the slim chassis design. At the swingarm pivot, the lower part of rear frame is supported by two sleeves through which the swingarm bolt passes. This enables a narrower design between the rider’s feet, facilitating the reach to the ground.
Rigid-mount engine is a stressed member, contributing to the frame’s idealised rigidity balance, and to the bike’s excellent handling and stability.
Frame geometry contributes to light, natural handling.
Footpegs are positioned relatively high so that they do not touch down easily, enabling stress-free cornering.
Optimized wheelbase balances light handling and a superior riding experience.

Suspension

Both front and rear suspension settings prioritize ride comfort.
Offset laydown single-shock rear suspension is equipped with linkage to enable a longer stroke for increased ride comfort.
The rear suspension arrangement also contributes to the bike’s compact design, freeing up space for a large-volume silencer under the engine.
Rear shock features adjustable preload, with seven positions to suit rider size and payload.

Brakes

Large 300mm front disc is gripped by a two- piston caliper and at the rear a 250mm disc is gripped by single-piston caliper.
The brakes provide ample stopping power.

Feeling comfortable—especially for a new rider—is one of the key factors when choosing a motorcycle. The Vulcan S was designed to be accommodating for a wide range of riders from short to tall. Complementing the relaxed riding position, adjustable footpegs and levers, and a number of accessory components allow riders to custom-fit their bike to suit size and preference.

Low seat height

Low 27.8-inch seat height allows riders to easily put their feet on the ground when stopped, one of the most important factors in feeling comfortable on a motorcycle.

Slim chassis design

The Vulcan S’ parallel twin engine enables a slimmer space between the rider’s legs since there is no cylinder there such as in a typical V-twin cruiser.
Slim, backbone-style rear frame contributes to the easy reach to the ground.

ERGO-Fit™ adjustability

Footpeg position can be adjusted to any of three positions: mid-reach, one inch forward, or one inch back. (Alternate shift linkage rods, sold separately, are necessary when changing the position from standard.)
Ergo-Fit™ reduced reach accessory handlebar positions the handle grips 1.7 inches closer to the rider.
Three different accessory Ergo-Fit™ seats adjust rider position: reduced reach positions rider closer to the tank and controls to accommodate shorter riders, mid-reach for average-sized riders is standard, and extended reach provides a more spacious seating position for taller riders.
Brake and clutch levers can be adjusted to suit the rider’s hand size and preference.

Comfort

Seat designed with thick padding to offer a wide surface and excellent hip support, ensuring ample comfort for city riding and short tours. The seat bracket is rubber mounted to reduce vibration transferred through the seat.
Footpegs are positioned for foot-forward control, creating a relaxed cruiser-style riding position.
Handlebar is rubber-mounted to reduce vibration transmitted through the handle grips.
Rider footpeg stays are rubber-mounted to further reduce vibration.

For riders who prefer not to follow the crowd, the unique design of the Vulcan S offers a stylish, modern alternative to the traditional cruiser image.
