Work hard, play harder. The all-new Suzuki GSX-8S features a torquey 776cc, 270° crank, parallel twin that delivers exciting performance and an exhilarating soundtrack throughout the rev range. A 5” TFT colour dash, bi-directional quick-shifter and aggressive design make for a refined yet thrilling ride on every journey.


The GSX-8S is propelled by an all-new 776cc DOHC 270° crank parallel twin engine, focussed on dynamic performance and delivers abundant torque for flexibility suited to a range of riders, paired with a powerful top end for an exciting and rewarding ride.


The new 776cc, DOHC, parallel twin engine with four valves per cylinder features a long-stroke configuration that delivers a fine balance of smooth, controllable power from low rpm and the enjoyable feeling of free-revving performance through to the top end. The engine features a 270° crankshaft design, which delivers a smooth ride with lots of torque, positive traction, and a unique, thrilling rumble.


The assist function leverages precision-engineered ramps to force the clutch boss and pressure plate together and efficiently transfer torque to the rear wheel under acceleration, all while using softer clutch springs. The slipper clutch partially disengages when downshifting and decelerating to mitigate the effect of engine braking and provides smoother deceleration, which enables the rider to shift down with greater confidence and maintain better control.

This patented biaxial primary balancer positions its two balancers at 90° to the crankshaft, marking a first among production motorcycles. This patented mechanism suppresses vibration to contribute to smooth operation, and it also helps achieve a lightweight powerplant that is more compact from front to rear.

Balancer no.1 cancels the primary vibration generated by the piston (reciprocating weight) of the first cylinder, while balancer no.2 cancels the primary vibration of the second cylinder. Adopting a 270° crankshaft angle cancels secondary vibration, contributing to even smoother engine operation. Furthermore, placing the two balancers at 90° to the crankshaft with each positioned equidistant from the crankshaft cancels primary couple vibration.


Designed around the new engine and made from steel tube sections, the frame is engineered to provide excellent straight-line stability, contribute to agile handling, and perform well in the city as-well-as at highway speeds. The new exposed subframe is designed to support the rider, and contribute to the GSX-8S’ slim appearance and stripped-down look.


Featuring a wheelbase that is longer than on a typical naked streetfighter, this contributes to straight-line stability, while the overall chassis geometry provides agile handling and cornering performance. A priority of the geometry is to provide a comfortable riding position that effectively distributes weight to the front and rear. The new engine benefits the geometry with its compact front-rear dimensions, allowing the positioning of the rider’s hip to point well-forward. This in turn enables the rider to shift their weight toward the front and more easily control the Suzuki GSX-8S when negotiating tight corners.


Radially-mounted front brake calipers biting 310mm floating discs provide strong stopping power and predictable braking performance. The rear brake uses a 240mm disc and a single-piston pin-slide caliper.

KYB inverted front forks with a 130mm stroke deliver a plush ride and feature stable damping characteristics that makes them suitable for a wide range of riding styles. The dedicated link-type mono-shock KYB rear suspension is set up to contribute to straight-line stability and agility, even when carrying a passenger.


The aluminium wheels feature a unique, lightweight design that adds style and contribute to the handling and sporty performance. They are fitted with a new generation of Dunlop RoadSport 2 radial tyres designed to perform optimally and provide consistent grip. The custom-engineered internal construction features a carcass and belt layer tuned to achieve the right level of rigidity to match the weight and performance characteristics of the Suzuki GSX-8S, and to deliver the right combination of agile handling and stability. Dunlop’s proven tread pattern introduces a new silica compound that enhances positive grip in wet conditions and features durable wear resistance.


The GSX-8S adopts an attractive aluminium swingarm with a unique shape that is engineered to perform with the right amount of vertical, lateral, and torsional rigidity providing confident handling stability and greater ride comfort.


The tapered aluminium handlebars are designed to provide a sporty-yet-comfortable upright riding position, and feature a wide enough grip to contribute to positive control.


Designed for comfortable and sporty riding. Delivering support for the rider toward its rear edge, the seat is shaped to offer freedom of movement and is covered in a material that provides positive grip. Featuring a slim design, the smoothly rounded edges of the seat also make it easier for the rider to plant their feet on the ground when stopped.

The Suzuki Intelligent Ride System (SIRS) is a collection of advanced electronic rider assist systems, which allow the rider to choose the settings for each system to best suit their preference or to suit the conditions. SIRS helps enhance an already exciting riding experience that inspires confidence and frees riders to concentrate on enjoying the ride.


The Bi-directional Quick Shift System allows riders to shift up without closing the throttle or downshift without blipping it, so removes the need to operate the clutch lever once the bike is in gear and moving.

The system automatically interrupts power delivery when accelerating and maintaining steady speed just long enough to unload the transmission gear dogs, thereby producing a smoother ride and uninterrupted acceleration when the rider shifts up. When decelerating the system automatically opens the throttle valves just enough to increase rpm and match engine speed to the next-lower gear ratio without manually blipping the throttle or using the clutch.


SDMS leverages the electronic throttle control system to offer a choice between three modes that deliver different power characteristics to match the riding conditions or preferred riding style. The settings for each mode were thoroughly tested to maximise the GSX-8S’s performance in various scenarios.

Mode A (Active) provides the sharpest throttle response as the throttle is opened. Settings for torque characteristics are tuned to deliver exciting acceleration and fully-leverage the engine’s power. It is well suited for enjoying sporty rides in good weather.

Mode B (Basic) reaches the same level of maximum output, but features a more linear curve with softer throttle response. Planned as an ideal setting for touring or commuting, this mode is a good fit for a wide range of riding styles and road conditions.

Mode C (Comfort) provides the softest throttle response and more gentle torque characteristics. This is particularly beneficial when touring for long distances, when riding with a passenger, when riding on wet or otherwise slippery surfaces, when road conditions are bad, or even when the rider wants to relax.

STCS2 for the Suzuki GSX-8S enables the rider to better control the bike in diverse and varying conditions, such as riding in inclement weather, and instils greater confidence regardless of the rider’s level of experience. The rider can select from three modes or turn the system off. The higher the number of the mode selected, the faster the control takes effect and the more proactive the system is in limiting wheel spin.


The GSX-8S uses a 5-inch colour TFT display. Clearly legible high-quality information displays keep you fully aware of all the bike’s systems and settings, and supply vital real-time operating status information. The tachometer doubles up as a programmable rpm indicator light that blinks when the engine reaches a pre-set speed, and adds a function that lets you display large pop-up alerts and reminder. Manual or automatic switching settings for the day (white) and night (black) display modes let you maximise visibility at any hour and in any riding situation.


The styling for the new Suzuki GSX-8S is based on the three core phrases: new era, visual structure, and icon. New era reflects the goal of creating a thoroughly modern design that sets a trend for an exciting new generation of motorcycles ready to carry the Suzuki brand into the future. Visual structure reflects the goal of exposing the bike’s functional parts, painting them in the new body colours, and simplifying the bodywork and graphics to put a spotlight on the visceral appeal of its structural elements. Icon reflects the goal to create a unique silhouette with an iconic presence that is instantly recognisable and symbolises the future of Suzuki design.


The vertically-stacked pair of hexagonal LED headlights are designed to emulate the GSX-S1000 and use a bright mono-focus LED light source that provides the rider with a clear view of the road ahead. The vertical orientation of the thin, compact headlight assembly creates a sharp look with unique character that makes the front end look light and ready for action. Compact LED position lights flank the headlights as they trace forward and down along the front cowl. The angled design of these narrow slits add to the unique face.
