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.

Low weight and low center of gravity make the Vulcan S 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 tothe 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 twopiston caliper and at the rear a 250mm disc is gripped by single-piston caliper.

The brakes provide ample stopping power.

Customers looking for an added degree of reassuring braking performance can also choose models with ABS that assists braking under certain conditions.

The compact ABS unit contributes to the lightweight chassis, and is conveniently tucked away under the rear shock, which ensures a slim construction beneath the seat.

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.
