2023 Suzuki GSX-8S

Description

Ready to make a statement? Swing a leg over the all-new 2023 Suzuki GSX-8S and let your riding speak volumes. Engineered from the ground up as an innovative path for future Suzuki sportbikes, the GSX-8S is a brand-new naked street fighter with a robust engine, an agile chassis, a suite of rider aids, plus stunning looks with a smart price that’s a statement to your brilliance.

Joining Suzuki’s popular GSX-S series of street fighters, the GSX-8S is the ideal response to rider demands in the mid-size naked street bike category. In response to these demands, Suzuki engineers created a fully new package in a complementary engine and chassis size packed with the most desirable features in its category.

The new 776cc DOHC parallel twin engine employs 270-degree crankshaft timing with the industry-exclusive Suzuki Cross Balancer to deliver a smooth, torque-rich experience. This is ideal for riders who desire more power than a 650cc engine can deliver and does so in a reassuring and reliable way.

The rugged steel backbone frame takes advantage of the new engine’s compact size, resulting in a chassis that is nimble and stable on country roads, city streets, or the open highway. That wide ranging performance is achieved through quality suspension and braking components that provide Supersport-levels of performance.

A new, color 5-inch TFT LCD multifunction instrument panel provides the rider access and on-the-fly control over the Suzuki Intelligent Ride System (S.I.R.S.) suite of advanced electronic control systems that includes Suzuki Drive Mode Selector, the Suzuki Traction Control System*, and Suzuki’s Bi-directional Quick Shift system. Plus, the rider can enjoy that control in a sporty, yet ergonomically comfortable riding position.

Wrapped in unique styling and eye-catching colors, the GSX-8S features an aggressive, mass-forward look that is slim, compact, well balanced, and ready for action. The new GSX- 8S is set to become the best choice for street riders of all experience levels, so get to your Suzuki dealer and make your own statement.

*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. Traction control cannot prevent the front wheel from losing grip.

Specifications

Features

The fully new GSX-8S is a thoroughly modern street fighter design that sets a trend for an exciting new generation of Suzuki motorcycles ready to carry the brand into the future.
The Suzuki Clutch Assist System (SCAS) smooths shifting and engine braking, while shifting has never been easier with the Bi-directional Quick Shift system.
The GSX-8S uses the Suzuki Intelligent Ride System (S.I.R.S.) with a three-mode Suzuki Drive Mode Selector and the four-mode Advanced Traction Control System* plus the popular Easy Start & Low RPM Assist systems.
New, compact 776cc parallel twin engine uses a 270-degree firing order for strong torque production and is equipped with Suzuki’s exclusive Cross Balancer system for smooth operation.
High-quality KYB suspension delivers controlled handling while ABS-equipped** NISSIN radial-mounted 4-piston brake calipers with dual brake rotors provide controlled stopping power.
Select from Suzuki’s Pearl Cosmic Blue, Pearl Tech White, or Metallic Matte Black No. 2 / Glass Sparkle Black paint scheme – each featuring unique logos that help identify the sport’s newest sportbike. *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. **Depending on road surface conditions, such as wet, loose, or uneven roads, braking distance for an ABS-equipped vehicle may be longer than for a vehicle not equipped with ABS. ABS cannot prevent wheel skidding caused by braking while cornering. Please ride carefully and do not overly rely on ABS.

The new design 776cc parallel-twin DOHC engine delivers a superb balance of smooth controllable torque-rich power from low RPM and freely revs up to its peak power output.
The spaced nature of the engine’s power pulses enhances traction and contributes to strong power output at extremely low speeds, making the GSX-8S easy to maneuver in slow traffic or through tight corners.
The pistons were developed using FEM (Infinite Element Method) analysis to maximize strength and minimize weight.
Dual, linked 42mm electronic throttle bodies use a newly configured Accelerator Position Sensor (APS) to provide an authentic response and feel to the rider’s throttle operation.
The 6.0L air cleaner box shape and intake pipe lengths were created using computer-aided design to help maximize peak power output plus strong torque production at low engine speed. Positioned under the seat, the air box size and shape contribute to the GSX-8S’s slim chassis.
The digital ignition fires iridium-type spark plugs that increase spark strength and combustion efficiency, contributing to higher power, more linear throttle response, easier engine start-up, and a more stable idle. These quality components also last longer than conventional spark plugs.
The unique cooling system inlet control thermostat valve helps maintain consistent engine temperature and smooths the idle speed during warm-up. This helps stabilize combustion and contributes to reduced exhaust emissions.
The 270-degree crankshaft configuration provides a similar, but more powerful experience as provided by the 90-degree V-twin engine used in the SV650 models.
Suzuki Cross Balancer technology, patented by Suzuki and used for the first time on a production motorcycle, helps create a compact, lightweight design that delivers smooth operation.
The 84mm cylinder bores inside the aluminum die-cast cylinders are plated using Suzuki’s SCEM process. Originally developed for racing and proven on the track, the SCEM cylinder promotes better heat dissipation, reduces friction, and provides a consistent wear resistant seal to the pistons’ rings.
The GSX-8S has two 10-hole, long-nose, 49 PSI (343kpa) high-pressure-feed fuel injectors that maximize fuel atomization for better combustion efficiency and lower fuel consumption.
The GSX-8S has a new, distinctive short muffler design that produces an exciting and unique exhaust note. Most of the exhaust system is located under the chassis in an optimal, centralized location that benefits handling. The stainless-steel 2-into-1 exhaust system uses a high flow, dual-stage catalytic converter inside the mid-pipe that helps satisfy worldwide emissions standards. From the mid-pipe, the exhaust flows into an under-chassis chamber that has a short new muffler design with an upswept end cap that slightly protrudes from the right side of the chassis.
A large capacity radiator effectively cools the parallel twin’s power output. A thermostatically controlled cooling fan helps stabilize coolant temperatures at low speed and stops.
Additional heat is removed from the engine via the use of a lightweight and compact liquid-cooled oil cooler (like those used on certain GSX-R models).

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 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.
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.
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.

Designed around the new, compact parallel twin engine and constructed with rugged steel pipe, the GSX-8S’s backbone style frame was developed to provide excellent straight-line stability, to contribute to nimble handling, and to perform well in the city, on twisty roads, and at highway speeds. The engine is suspended and precisely fit to the frame to create a rigid chassis that also provides the compliance required for sport riding. The frame and engine package helps create sporty chassis geometry with rider-friendly ergonomics.
Matched to the GSX-8S’s chassis geometry and suspension is a new, uniquely shaped aluminum swingarm that enhances vertical, lateral, and torsional rigidity to aid straight-line stability and controlled cornering.
The GSX-8S rides on new design, 17-inch lightweight, cast aluminum wheels that look great and contribute to the bike’s nimble handling and sporty performance. Front rim size is 17 x 3.5 in., rear rim size is 17 x 5.5 in.
Dual front brakes with 310mm diameter discs and radially mounted NISSIN four-piston calipers provide strong and consistent stopping power.
Both the front and rear brakes can be modulated by a compact Anti-lock Brake System (ABS)** controller to match stopping force to the available traction.
The GSX-8S features an upright riding position for superior comfort and control. The compact parallel engine allows the rider’s foot pegs to be set further forward, creating a reasonable sport riding position between the handlebar, footrests, and seat. The matte black tapered cast-aluminum handlebar contributes to the excellent riding ergonomics, with great vibration damping and a performance-oriented style. In addition to increased comfort and a more upright posture, these changes make it easier for the rider to steer the front end with less effort.
The rider’s seat is designed for comfortable sport riding, delivering solid support for the rider. The rear edge of the seat is shaped to offer freedom of movement and is covered in a cover that provides positive grip. Compared to the GSX-S750, the seat is lower, with a low height of 31.9 inches (810 mm), and contributes to the sporty, yet upright riding position and helps riders plant their feet on the ground when stopped. Positioned on the motorcycle higher so the passenger can see over the rider’s shoulder, the rear seat shape matches the GSX-8S’s angular styling but has ample padding. This separate pillion seat includes a hand strap for the passenger and can be replaced with an optional sport cowl for solo rides with a race-inspired style. Both seats are covered in a rugged, weather-resistant cover that provides a good balance between grip and smooth movement.
The 3.7-gallon (14L) fuel tank has narrow rear section that flows into the front of the rider’s seat, creating additional clearance for the rider’s knees. The internal construction and cap of the fuel tank were engineered so the gasoline capacity is the same for both the 49-state and California versions.
The steel sub-frame has short and narrow seat rails that result in low and slim seating that helps riders maneuver the motorcycle and touch the ground at stops. GSX-8S seat height: 31.9 in. (810 mm).
Created solely for the GSX-8S, the front fork and single-shock rear suspensions’ spring rate and valving were tuned to maximize performance and comfort when riding on city street or twisty roads. The KYB-supplied inverted fork has 41mm inner tubes with 5.1-inches (130 mm) of travel delivers a plush, controllable ride thanks to carefully selected spring rates and damping characteristics that are well suited to sporty rides or long-distance runs. The link-type mono-shock KYB rear suspension is set up to contribute to straight-line stability and agility, even when carrying a passenger. Rear wheel travel is 5.1 in. (130 mm). The cam-style spring preload adjuster is particularly useful when heading out to ride tandem or adding cargo.
Dunlop’s new-generation Roadsport 2 radial tires (120/70ZR17 at the front and a wide 180/55ZR17 at the rear) are custom-engineered to perform optimally on the GSX-8S, providing great grip in dry or wet conditions, faster warm-up, and long tread life. These new wheels and tires were developed to work in harmony with the new KYB suspension to provide great grip, stability and nimble handling while providing a comfortable ride.
The front brakes are complemented by a 240mm stainless-steel rear disc brake with a NISSIN single-piston caliper to help ensure controlled stops.
The GSX-8S features a wheelbase that is longer than a typical naked street fighter, and this contributes to straight-line stability. Even so, the chassis geometry was adjusted to ensure nimble handling and cornering ability, while keeping the motorcycle compact.
The front brake lever features a multi-step adjuster that permits quick adjustment of the lever’s distance from the grip.
The front fender features a bold upright strut that extends upward toward its leading edge. In addition to adding strength, this strut contributes to the GSX-8S’s sporty appearance.

The GSX-8S fulfills the goal of creating a thoroughly modern design that sets a trend for an exciting new generation of Suzuki motorcycles ready to carry the brand into the future. As the 2022 GSX-S1000 established a new design direction featuring sharp lines and an edgy futuristic look, the GSX-8S takes it’s styling to an exciting new space. The angular stacked LED headlights within the pointed upper cowling are further defined by strips of position lights that bring a unique new face to motorcycling. The fuel tank’s front cover flows into the larger, pointed radiator shrouds that protrude past the fork legs bringing further attention to the pointed upper cowling. The bike’s sharp nose is offset by the short, compact muffler outlet, exposed subframe, and slim tail section creating a compact body that emphasizes the new parallel twin engine.
The GSX-8S adopts the fresh new graphics and fonts that first appeared on the 2022 GSX-S1000. This not only connects this new model to the S1000’s naked roadster legacy, but further emphasizes the “8S” moniker which resembles the endless loop of the infinity symbol.
The 2023 GSX-8S boldly arrives with three body color choices: Pearl Cosmic Blue (QU1): is a brand-new color created exclusively for the GSX-8S. Its bright, solid pearl finish creates an appearance that changes depending on how the light strikes it, even providing the impression the body is illuminated in low light settings. Pearl Tech White (QU2): is also introduced for the first time on any Suzuki, this bold, pearly white finish creates a mechanically futuristic appearance. The Pearl Cosmic Blue wheels, exposed blue sub-frame, and graphics make the entire motorcycle stand out in any setting. Metallic Matte Black No. 2 / Glass Sparkle Black (KGL): Suzuki’s popular, glossy, and flat black combination finish perfectly captures the GSX-8S’s street fighter soul.
Attention to detail extends to the engine as the clutch cover and magneto cover have a dark-gray finish that complements the GSX-8S body colors, while the SUZUKI name on the cover is in a contrasting silver to bring attention to the new, fully modern engine.

The 2023 GSX-8S instrument panel uses a new-generation 5-inch, color TFT LCD screen.
The brightness adjustable TFT display delivers a wide range of useful information, keeping the rider fully aware of all the bike’s systems, settings, and real-time operating status. The display can be set for manual or automatic switching between Day Mode (white background) and Night Mode (black background). The display’s general brightness can be set to automatically adjust to the ambient light-level, or manually set to suit the rider’s preference.
The main TFT panel is flanked by LED indicators, including: Left-turn signal indicator, MIL (Malfunction Indication Lamp), neutral indicator light, master warning indicator, high-beam indicator light, right-turn signal indicator, TC (Traction Control) indicator, low oil pressure warning light, ABS indicator, and coolant temperature warning light.
The handlebar switches are designed for intuitive operation (so the rider can better maintain focus on the road). The right handlebar switch includes a poly-function engine stop-on-start rocker switch and a hazard flasher switch. The left handlebar switch was designed so selecting modes and making settings and adjustments for each of the advanced S.I.R.S. features simply involves operating the MODE button and the UP/DOWN switch (which recognizes long and short presses). Headlight control is literally a flip of the finger – the left index finger to be precise. Set on the forward side of the left handlebar switch, the headlight control lever easily toggles between low beam, high beam, and flashing the high beam.
Thin, compact LED position lights trace the forward section of the front cowl. The angled design of the narrow slits of bright light add to the unique appearance of this new streetfighter.
With lower electrical draw than conventional lighting, the LED headlights, position light, turn signals and taillight complement the GSX-8S’s sharp, angular styling while improving both visibility and durability.
This high-quality instrument panel is set into the upper cowl above the handlebars, for good visibility and protection from road debris. The TFT panel features a scratch-resistant surface, and an anti-reflective coating that improves visibility in bright light.
The TFT panel provides operational information in an easily recognizable way: The left side of the panel has an analog tachometer animation with a sweeping red needle that accurately shows engine speed all the way up to the 9,500 RPM redline. The tachometer can be preset to flash at certain engine speeds, acting like a shift light (it can be set in 250 RPM increments within a range from 4,000 to 9,500 RPM).
To the left, center of the panel is a digital speedometer, quick-shift system status indicator, and gear position indicator. Directly below the speed display is a fuel level gauge. The upper right portion of the panel displays the clock and S.I.R.S. feature information such as the Traction Control, and S-DMS settings. Depending upon the rider’s selection, the lower portion of the right side of the panel can display coolant temperature, ambient air temperature, odometer, dual tripmeters, fuel consumption, and riding range. The panel can also be configured to display large pop-up alerts and warnings. These alerts can present service reminders or advise of an operational issue.
The charging system uses a durable, oil-cooled three-phase stator. A high-capacity, maintenance-free style battery and fuses are easily accessible under the seat. Charging output is 375W @ 5,000 RPM
The GSX-8S front cowl houses a stacked pair of hexagonal headlights that employ the bright, Mono-focus LED light technology that provides the rider clear and bright illumination of the road ahead. Supplied by Koito®, the independent, polygon-shaped, high- and low-beam headlights feature Mono-focus LED technology that shines light directly through a convex lens to brightly illuminate the road.
The GSX-8S’s front LED turn signals are mounted in thin, arrow-shaped housings, extending outward from the upper portion of the front cowl. Mounted to the side of the rear LED taillight the rear turn signals use the same lightweight and low-draw LED illumination as the front signals.

A variety of Genuine Suzuki Accessories are available for the GSX-8S, such as a solo seat cowl, meter visor (acting as a sport screen), billet clutch and brake levers, fuel tank and engine cover protectors, clip-on tank bags, plus a selection of Suzuki logo apparel.
