Joining the inline-four GSX range, Suzuki have delivered something fresh with the punchy parallel-twin GSX-8S. We put it to the ultimate test on road and track... Pics: iKapture Footage: Black Fox Media

We spent a day on the roads and a day on track testing the all-new Suzuki GSX-8S parallel-twin nakedbike. Well priced, with a cracker of an engine, versatile chassis, quick-shifter, traction control, ride modes and ABS, the new 8S has it all…



TECH TALK, 2023 Suzuki GSX-8S

Engine
The parallel-engine has a 270-degree crankshaft configuration with a patented Suzuki Cross Balancer – two balancers positioned at 90 degrees to the crankshaft – contributing to even smoother operation. The Euro5 engine, which is also used in the all-new V-STROM 800DE, has a maximum output of 62kW@8500rpm and peak torque of 78Nm@6800rpm.



The two-into-one exhaust system has a dual-stage catalytic converter inside the collector which helps satisfy Euro5 emissions standards, and the striking design features a short new muffler – the shortest ever mounted on a Suzuki motorcycle – that barely rises up and out from the right side of the engine.

Electronic throttle-bodies help achieve a linear throttle response and superb mechanical grip, while other key pillars of the Suzuki Intelligent Ride System (SIRS) include multiple ride modes, three-stage traction control (plus off), ABS, a Bi-directional quick-shifter and Suzuki’s Easy Start System.

  • Suzuki Cross Balancer, the first of its type on a production motorcycle, contributes to smooth operation and a compact, lightweight engine design.
  • Cooling system inlet control helps maintain consistent engine temperature and eliminate rough idle while warming the engine in cold weather.


  • The electronic throttle-bodies help achieve faithful response and a linear feeling to throttle action.
  • The 2-into-1 exhaust system features a dual-stage catalytic converter inside the collector that helps satisfy Euro 5 emissions standards and a striking new short design
  • The six-speed transmission realizes smooth shifting and improved controllability.
  • Suzuki Clutch Assist System (SCAS) helps reduce fatigue on long rides and contributes to smoother shifting. 

Just like the parallel-twin engine, the steel frame in the GSX-8S is a completely new design, contributing to comfort, stability and nimble handling.

Chassis
Just like the parallel-twin engine, the steel frame in the GSX-8S is a completely new design, contributing to comfort, stability and nimble handling. The machine also has a unique aluminium swingarm, KYB suspension, Nissin radial-mount monobloc brakes and cast-aluminium wheels with Dunlop Sportmax Roadsport 2 rubber.



Designed around the new engine platform and made from rugged steel pipe, the frame was engineered to provide excellent straight-line stability, to contribute to nimble handling, and to perform well in the city and at highway speeds. This includes providing solid handling stability when the genuine accessory soft side case set is mounted.

Radial mount front brake calipers mated with 310mm floating dual discs provide sure stopping power and controllable braking performance. The rear brake has a 240mm disc and uses a more basic single-piston pin-slide caliper.



Suzuki say that the KYB inverted front forks with a 130mm stroke deliver a plush, controllable ride and feature stable damping characteristics. 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 cast-aluminium wheels feature a unique new lightweight design. They are shod with a new generation of Dunlop RoadSport 2 radial tyres (120/70ZR17 at the front; 180/55ZR17 at the rear). 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 GSX-8S. Dunlop’s proven tread pattern introduces a new silica compound that enhances positive grip in wet conditions and features durable wear resistance. Wet weight is just 202kg, including 14 litres of fuel.

Electronics
The Suzuki Intelligent Ride System (S.I.R.S.) features a collection of advanced electronic rider assist systems. The rider can freely choose the settings for each system to best suit their level of skill and experience, and to optimise performance characteristics for the conditions and road surface.These settings in turn help make the GSX-8S more controllable, predictable, and less tiring to operate. With each system designed and thoroughly tested to operate the way the rider expects.



The robust collection of advanced S.I.R.S. electronic systems employed by the GSX-8S include the Suzuki Drive Mode Selector (SDMS), Suzuki Traction Control System (STSC), Ride-by-Wire Electronic Throttle System, Bi-directional Quick Shift System, Suzuki Easy Start System, and Low RPM Assist.


Suzuki Intelligent Ride System (S.I.R.S.) Highlights

  • Suzuki Drive Mode Selector (SDMS) better supports the rider in matching performance to the conditions of the riding scene, road conditions, or preferred riding style.
  • Suzuki Traction Control System (STCS) with 3 mode settings (+ OFF) enables greater control over the bike’s behavior under diverse riding conditions.
  • Suzuki’s Ride-by-Wire electronic throttle control system realizes throttle action that responds faithfully to the rider’s every intention.


  • Suzuki’s Bi-directional Quick Shift System (with ON/OFF settings) provides quicker, smoother, more assured shifting without operating the clutch lever while in motion.
  • The ABS system contributes to more stable braking by helping prevent the wheels from locking up, even under hard braking.
  • 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.
  • The GSX-8S’s custom 5-inch full-color TFT LCD multi-function instrument panel features a
    clearly legible display of a rich variety of information.


Styling
In developing the styling for the new GSX-8S, Suzuki’s design team set a goal based on the three keywords, “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 brand into the future.



The 14-litre fuel tank features a stunning slim design unique to the GSX-8S, and the electronic equipment includes a five-inch TFT multi-function dash, all-LED lighting – including vertically stacked headlights – and distinctively styled LED daytime running lights.

The 2022 model GSX-S1000 established the beginnings of a new design language featuring sharp lines and an edgy futuristic look. And now the GSX-8S is ready to take the ball and carry it.
