All-New Suzuki GSX-8S Features 776cc Parallel-Twin

The long-rumored, mid-displacement Suzuki parallel-twin engine made its debut earlier today at EICMA in two new models, including the naked GSX-8S seen here and a new V-Strom (look for an MD article on this new Adventure bike). The new engine looks impressive on paper with a 270 degree crank mimicking the power pulses of a v-twin, and a sophisticated, patented double balancer-shaft design that Suzuki claims creates an extremely smooth, low vibration engine.

The new GSX-8S also gets a bright 5″ TFT display, selectable rider modes and a quick shifter, among other features. U.S. availability is expected next Spring. European speculation on pricing would put this model in the $8,500 U.S. range.

We noticed some pretty extreme lean angles in the photos of the new bike, so ground clearance appears generous. Here is the press release from Suzuki on this new model, followed by a video from English publication MCN:

Brea, CA (November 8, 2022) – The 2023 GSX-8S is brand-new, engineered from the ground up to deliver streetfighter performance for a new generation that’s sure to turn heads and Make a Statement.  Powerful, agile, and ready to go, the 8S offers a strong appeal to a broad range of riders, regardless of their age or riding experience.

The GSX-8S joins the Suzuki line featuring trendsetting naked sportbike styling combined with real-world performance, user-friendly electronic rider aids, confident handling, and optimized comfort. 

During the development of the new GSX-8S, Suzuki followed a strategic process aimed at creating superior performance and value by focusing on rider needs. Suzuki engineers aimed for the ideal combination of engine and suspension performance, ergonomics, and features. To reach this ideal combination in one bike, multiple optimization tests were conducted, with consumer feedback given to achieve an ideal balance. The new GSX-8S was refined through a strategic and constructive process, resulting in what we believe is the ideal middleweight street bike.

The new GSX-8S features Suzuki’s brand-new parallel-twin 776cc DOHC engine mounted in a new frame design. Marking a new innovative path for future Suzuki products, the GSX-8S is a brand-new naked middleweight streetfighter with a robust engine, an agile chassis, a suite of electronic rider aids, plus stunning looks, and a smart price that’s in line with the demands of a new generation of riders. Every aspect of the motorcycle is geared to deliver a satisfying experience to riders who desire more power than a 650-class motorcycle may deliver, and who desire a satisfying ride that is exciting and dependable.

Wrapped in Suzuki’s new generation styling for the GSX line, the GSX-8S features an aggressive, mass-forward look that is slim, compact, well-balanced, and ready for action.

Key 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. 
  • All-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
  • The Suzuki Clutch Assist System (SCAS) smooths shifting and engine braking, while shifting has never been easier with the Bi-directional Quick Shift system. 
  • High-quality KYB suspension delivers controlled handling while ABS-equipped** NISSIN radial-mounted 4-piston brake calipers with dual, floating brake rotors provide controlled stopping power.
  • 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 Suzuki’s popular Easy Start & Low RPM Assist systems. 
  • 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 and graphics that help identify the sport’s newest performance motorcycle.

GSX-8S New Parallel-Twin Engine:

  • The 270-degree crankshaft configuration provides a comparable, but more powerful experience as provided by the 90-degree V-twin engine used in the SV650 models.
  • The spaced nature of the engine’s power pulses enhances traction and contributes to ample power output at extremely low speeds, making the GSX-8S easy to maneuver in slow traffic or through tight corners. 
  • Suzuki Cross Balancer technology, used for the first time on a production motorcycle, helps create a compact, lightweight design that delivers smooth operation. 
  • The pistons were developed using FEM (Infinite Element Method) analysis to maximize strength and minimize weight.
  • The 83mm 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.
  • 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 GSX-S8 has two ten-hole, long-nose, 49 PSI (343kpa) high-pressure-feed fuel injectors that maximize fuel atomization for better combustion efficiency and lower fuel consumption.
  • 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-S8’s slim chassis.
  • 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.
  • 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.
  • A large-capacity radiator effectively cools the parallel twin’s power output. A thermostatically controlled cooling fan helps stabilize coolant temperatures when riding at low speed and constant stops.
  • 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. 
  • 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).

SUZUKI Intelligent Ride System (S.I.R.S.) Features:

  • A Suzuki Drive Mode Selector (S-DMS) supports the rider in matching performance to the riding and road conditions, or the rider’s preferred riding style.
  • There are three standard mode settings in the Suzuki Traction Control System (STCS) for the GSX-8S. The settings for each mode were custom-tuned and thoroughly evaluated to maximize the GSX-8S’s capabilities as a top-performing streetfighter, with the flexibility to adapt well to changing weather, road, and riding conditions, and to make the overall riding experience exciting and enjoyable in these conditions.
  • Suzuki’s ride-by-wire electronic throttle control system offers throttle action that responds faithfully to the rider’s every input.
  • Suzuki’s legendary Bi-directional Quick Shift System (with ON/OFF settings) provides quicker, smoother, more assured shifting, without operating the clutch while in motion.
  • The ABS system contributes to more stable braking by helping prevent the wheels from locking up, even under hard braking. The system is programmed to monitor wheel speed and match stopping power to the available traction. The ABS control unit features a compact, lightweight design that contributes to making the bike nimbler.
  • The Suzuki Easy Start System starts the engine with one quick press of the starter button.
  • Suzuki’s Low RPM Assist function helps maintain engine idle speed for smoother and easier starts.

GSX-8S Chassis:

  • A rugged new steel frame developed for the GSX-8S contributes to comfort, straight-line stability, and nimble handling.
  • The new exposed seat rails are engineered to support the rider well, and also to contribute to the GSX-8S’ slim appearance and stripped-down look of functional beauty. 
  • KYB inverted front forks with a 130mm stroke deliver a plush, controllable ride and feature stable damping characteristics that make them suitable for both sports riding and long-distance rides.
  • 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 mechanical preload adjuster is particularly useful when heading out to ride tandem.
  • Radial mount front brake calipers mated with 310mm outer diameter floating-mount dual discs 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.
  • The cast-aluminum wheels feature a unique new lightweight design that looks great and contributes to nimble handling and sporty performance.
  • The GSX-8S is shod with a new generation of Dunlop RoadSport 2 radial tires (120/70ZR17 at the front; 180/55ZR17 at the rear) designed to perform optimally and provide consistent grip in a variety of street riding conditions. 
  • The GSX-8S uses a uniquely shaped, lightweight aluminum swingarm offering enhanced torsional rigidity to better support the increased suspension travel and contribute to straight-line riding stability.
  • The fuel tank features a 14L (3.69 gals) capacity that helps deliver the right balance between riding range and slim, compact looks that heighten the appeal of the GSX-8S’ sporty styling.
  • The tapered aluminum handlebars provide a sporty yet comfortable upright riding position and feature a wide enough grip to contribute to positive control when steering the GSX-8S.
  • The rider’s seat is built for comfortable sport riding. Delivering solid support for the rider toward its rear edge, the seat is shaped to offer freedom of movement and is covered in durable materials that offers a positive grip.

    The only twin 800cc I would buy is a 90 degrees V or L, otherwise give me a four cylinders…

  2. carl says:

    This is getting a little boring………

  3. David says:

    I love the engine, the technology, wheels, pretty much everything except the cosmetic style, including: headlights and housing, plastic flaps attached to the tank, the short seat section and that long stinger (rear fender?). Modern sportbike style seems to get more insectile and birdlike.
    I’m over 50 and the owner of a 1st year GSXR 1100. It’s not comfortable, but it is fun to ride and look at. Not sure if I’m biased, but I think the best looking sport-bikes are the 90s models. I wish we would go back to a more hefty style. The high or non-existent tail-end and the alien style of the front-ends of the latest bikes is not appealing. I’m not a huge fan of the new retro bikes, and wish we still had sportbikes that draw you to them in the showroom.

    • viktor92 says:

      Totally agree, the new bikes, with few exceptions, are ugly and a mix of alien and transformer. We are many that think that ’90 bikes are the best looking ones. I’m 60 and owner of a ZX11 D and I love the style and the rounded and aerodynamic lines.

  4. Jim says:

    Now we just need Kawasaki to bump their P-twin to 700-900 and join the club.

  5. todd says:

    800; the new 650. Progress marches on.

  6. yellowhammer says:

    The motor is cool. The right size & wt. I didn’t read all the article – what is the purpose of those crab-like pincer/wing thingies that stick out from the sides of the gas tank and wrap up around the fork? Does form follow function or is it a manga/origami fashion statement?

    • Mick says:

      The pincers are there to emulate the radiator shrouds on a dirt bike. Much like the “beak” that a lot of guys whine about is there to emulate a dirt bike fender on an adventure bike. I guess they feel that by adding dirt bike elements, they can get the dirt bikers to overlook the fact that these things still weigh as much as two dirt bikes.

      That’s not happening. Most dirt bikers see street bikes as Frankenstein steam punk engineering atop Flintstone suspension components. And, for the most part, they are right. The speed sensitive suspension the Yahama started equipping their dirt bikes with in 2006 has yet to make it onto a street bike for instance. Dirt bikes gained only seven pounds when they were suddenly equipped with a battery and electric start. And they have since lost that seven pounds and more. Meanwhile street bikes have steadily gained even more weight. 500 being the new 400 pounds while many are closer to 600 or more. 400 pounds is still ridiculously heavy to a dirt biker. Recognizable radiator shrouds or fake supermoto fenders aren’t going to change that.

  7. Mrpokey says:

    Either that rider is very large or the bike looks very small.

  8. Trent says:

    So is Suzuki really pulling the plug on the GSXR-1000 in Europe and Japan?

  9. Neal says:

    To my eyes it looks likes it has been designed to have a faired version. Nice tech features, should be a winner if priced right.

  10. Tom R says:

    Okay, now use this engine and emulate a retro chassis akin to the GS850 from the 80s with a NICE WIDE FLAT SEAT.

  11. wncmcrider says:

    Been a Suzuki fan since racing an X6 in the late ’60. My question is, if I were to take my best girl out for a weekender on this bike, where would we carry our toothbrushes?

    • Motoman says:

      You would carry your toothbrushes in another bike or your car. Because you knew when you bought this bike that you wouldn’t use it for over-nighters without buying some accessories.

      With all the motorcycle options available today why is this question regularly asked?

      • Mick says:

        So many bikes on the market now days are openly hostile towards utility.

        What’s sad is that these designs aren’t bringing any benefits. Here’s a new parallel twin, which should be lighter. It’s in a paired down chassis, which should be lighter because anything that isn’t there is weightless.

        But does it weigh less than a twenty year old open class sport bike from the same company? Well, no. It weighs a considerable percentage more.

        Some storage for a couple of toothbrushes isn’t really a lot to ask. One gets a bit tired of getting so much nothing from the onward march of technology.

      • JohnB says:

        Toothbrush How about a six-pack of thongs for milady.

    • SVGeezer says:

      “where would we carry our toothbrushes?”


    • cw says:

      I think that’s what those various luggage accessories with the Suzuki logo on them are for.

  12. cw says:

    For the life of me, I can’t remember this Pokemon’s name…

    and…why not “S8” if putting this in the GSX family?

  13. Dave says:

    Looks like the new Hornet has some direct competition. Both should be less than $1k more than an MT07, Z650 or SV650 for arguably a lot more bike. This thing does have a small fuel tank for a 750+cc engine. I prefer the Honda’s looks. Looking forward to reading the ride reviews and seeing them in person. Might have to let go of the ol’ VFR.

    • Artem says:

      SV650 is discontinued. May be I’m wrong.

      • Dave says:

        Is it? Shows current 2022 on their website. I wouldn’t be surprised if they let it sunset with this new bike coming.

        • Fred N says:

          On the UK press launch, the Suzuki Guy said that the SV650 would run in tandem with the 8S next year. He expressed a view that the SV650 would be the lower priced bike and the GSX-S 1000 the upper priced bike. The 8S in the middle.

          • Dave says:

            It would make sense to let the SV650 go. It’s almost 24 years old now and Making a v-2 is more expensive than a p-2 and also harder to package. I won’t be surprised if a 500-600cc version of this new engine doesn’t emerge in the next year or two.

  15. SparkyK says:

    God, what is with all of these fugly bird-beaked looking bikes coming out? KTM is not who Honda, Kawasaki, and Suzuki should be emulating when it comes to style.

  16. Curly says:

    I like it. The price is right, it’s well equipped, big brakes, the stance is good and the power plant should be like a stronger MT-07. Throttle by wire will allow cruise on a touring version.

  17. motomike says:

    Huh, a bug with the stinger in front. At least it’s something new from Hammatsu.

  18. Nick says:

    Definitely state of the art: Finite Element design (of the pistons) has now advanced to Infinite Element design! But then, what would the marketing dept know about such things?

    Naturally, no prizes for style.
