TRANSMISSION & DRIVELINE FEATURES
The six-speed transmission features gear ratios that deliver exciting acceleration, whether shifting normally or when using the standard-equipment Bi-directional Quick Shift system to shift without clutch operation.
The GSX-8S’s precise shift linkage helps the rider easily and quickly select the ideal gear for the riding conditions.
A sensor on the shift rod sends shifter movement data to the ECM, so the Bi-directional Quick Shift system precisely responds to the rider’s actions.
The transmission’s output is managed by the Suzuki Clutch Assist System (SCAS). This system works like a slipper clutch by allowing a small amount of clutch slip for smoother downshifts. It also works as an assist clutch, increasing plate pressure under acceleration, but always keeps the clutch lever pull light and precise.
This large-diameter, wet, multi-plate clutch uses a precise cable-activated release, providing the rider with a light pull that also has superb friction-point feel.
Riding on durable steel sprockets, a strong O-ring style drive chain contains lubrication pre-packed between the pins and rollers for quiet, reliable operation.
The chassis is engineered to be slim, compact, lightweight, highly agile, and ideally suited to supporting the high-performance parallel twin engine. Every aspect reflects a strong focus on great handling and control, and on minimizing fatigue.
A highly rigid steel frame contributes to comfort, straight-line stability, and nimble handling.
The exposed seat rails provide solid support, while also contributing to a slim appearance and stripped-down look of functional beauty.
The long wheelbase (1,465mm) contributes to straight-line stability. Even so, the overall chassis geometry helps ensure nimble handling, cornering ability and a comfortable riding position with effective front-rear weight distribution, and the design still makes the bike appear compact.
Dual radial mount front disc brake calipers act on ø310mm discs to provide sure stopping power and controllable braking performance. The rear brake has a 240mm outer diameter disc and uses a single-piston pin-slide caliper.
KYB inverted front forks with a 130mm stroke deliver a plush, controllable ride and feature stable damping characteristics that makes them suitable for both sports riding and long-distance runs.
Adjustable KYB link-type rear suspension contributes to agility and stability. 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. And the settings are optimized to help realize nimble handling and predictable steering into corners.
Lightweight cast aluminum wheels contribute to agile handling and the sporty, futuristic appearance of the GSX-8S’ sharp styling.
Dunlop SPORTMAX Roadsport 2 tires (120/70ZR17 at the front; 180/55ZR17 at the rear) contribute to nimble, predictable handling and sporty performance. The tires feature an internal construction custom-engineered to match the characteristics of the GSX-8S and perform optimally, and a silica compound that enhances grip in wet conditions and durable wear resistance.
Features a uniquely shaped lightweight aluminum swingarm with enhanced torsional rigidity that contributes to nimble handling, straight-line stability, and ride comfort.
Tapered aluminum handlebars contribute to positive control and an upright riding position that offers comfort combined with a sporty riding experience.

Exposed parts proudly highlight the mechanical appeal of the engine, frame, and other functional components. All combined, the styling creates an aggressive, futuristic mass-forward look that is slim, compact, well balanced, and ready for action.
Adopting the design concept, “an icon for a new era of functional beauty”, Suzuki’s design team based its GSX-8S styling goals on the following three keywords. “New Era” reflects the goal of creating a thoroughly modern design that sets a trend for an exciting new generation of motorcycles. “Visual Structure” reflects the goal of exposing the bike’s functional parts, painting them, 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 futuristic silhouette with iconic presence that is instantly recognizable from a distance and symbolizes the future of Suzuki design.
SUZUKI INTELLIGENT RIDE SYSTEM (S.I.R.S.) FEATURES
The advanced electronic systems of the Suzuki Intelligent Ride System (S.I.R.S.) featured on the GSX-8S assist and help you optimize performance characteristics to match your changing riding needs and preferences. By making the GSX-8S feel more controllable, predictable, and less tiring to operate, these systems help you ride with greater peace of mind.
Suzuki Drive Mode Selector (SDMS) lets you freely choose among three different power output characteristic modes to best match varying riding conditions or your preferences. While all three ultimately deliver maximum engine output, finer control over response and torque characteristics as you open the throttle to accelerate empowers you to ride with greater confidence and pleasure.
- Mode A (Active)
Delivers the sharpest throttle response as you open the throttle. Torque characteristics are finely tuned to deliver exciting acceleration as the throttle is opened.
- Mode B (Basic)
Features softer throttle response and a more linear power delivery curve as you open the throttle. Settings are tuned to help make the bike more controllable and a good fit for everyday riding.
- Mode C (Comfort)
Offers yet softer throttle response and more gentle torque characteristics. This mode is useful when riding on wet or slippery surfaces.
The Suzuki Traction Control System (STCS)* is designed to help prevent rear wheel slip, thereby reducing stress and fatigue while instilling greater conﬁdence in controlling your ride. You can select from 3 modes to control how quickly the system takes effect and how proactive it is in limiting wheel spin, or you can opt to run with it turned off.
Suzuki’s Ride-by-Wire Electronic Throttle System realizes linear feedback to throttle grip action that responds faithfully to your every intention and makes the GSX-8S feel more controllable.
The Bi-directional Quick Shift System lets you shift up or down while in motion without operating the clutch lever. When activated, this standard-equipment system delivers clean upshifts with smooth acceleration, as well as quick and easy downshifts. The gear shift linkage system load rate is optimized to provide a solid, satisfying click with each shift that assures you the gearbox has responded immediately to your action.
By helping prevent engine speed from dropping excessively when you pull away from a standing start or ride at low speeds, Low RPM Assist delivers smoother starts and inspires greater confidence when you are riding in stop-and-go traffic, or doing U-turns.
Suzuki Easy Start System lets you start the engine with just one quick press of a button. As a function used on every outing, it makes your riding experience all the more pleasurable and convenient.
* The Traction Control System is not a substitute for the rider’s throttle control. It cannot prevent loss of traction due to excessive speed when the rider enters a turn and/or applies the brakes. Neither can it prevent the front wheel from losing grip.
The vertically stacked pair of hexagonal LED headlights provides a clear view of the road ahead and features a sharp design with unique character. Compact LED position lights form narrow slits that trace down the front cowl to accent the face’s unique “mask”.
The LED rear combination light is integrated with the license plate light. Mounted on the slim rear fender, this light contributes to a sporty design that makes the GSX-8S look even shorter and slimmer in the rear.
The custom 5-inch color TFT LCD multifunction instrument panel features clearly legible displays that keep you fully aware of all the bike’s systems and settings in real time, and now adds a function that lets you display large pop-up alerts and warnings. Manual or automatic switching between day and night display modes lets you maximize visibility at any hour and in any riding situation.
The ergonomic handlebar switch layout maximizes operating ease and efficiency so you can intuitively access all controls while focusing on the road ahead. Select modes and make settings and adjustments for each S.I.R.S. control system by simply operating the MODE and UP/DOWN switches on the left handlebar.
