2025 Suzuki GSX-8S
The numbers
Where the price sits
A comparable set is anchored on this machine's odometer, and this listing does not publish one. There may well be machines like it on the board — there is just no way to line this one up against them. The ask is shown on its own instead.
A comparable is the same make, model, year and trim, within 3,999 miles of this odometer and 500 miles of this dealer. Unpriced listings are ignored, this one is excluded, and a dealer posting the same machine twice counts once.

What they say about it
2025 Suzuki GSX-8SDesigned to excite riders who value agility, power, and bold styling, the 2025 Suzuki GSX-8S is the latest addition to Suzuki’s renowned GSX-S series. This mid-size naked street bike packs a responsive 776cc DOHC parallel-twin engine with 270-degree crankshaft timing, ensuring a smooth, torque-rich ride. Enhanced by Suzuki’s Cross Balancer technology, the GSX-8S delivers the punch and precision riders demand, whether carving through twisty backroads, navigating the city, or cruising the open highway.Features may include:EngineThe new-generation 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 with a 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.The 84mm cylinder bores inside the aluminum die-cast cylinders are plated using Suzuki’s SCEM process. Dual, 10-hole, long-nose, 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.TransmissionThe 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 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.ChassisDesigned around the compact parallel-twin engine and constructed with rugged steel pipe, the GSX-8S’s backbone style frame was developed to provide excellent straight-line performance, to contribute to nimble handling, and to perform well in the city, on twisty roads, and at highway speeds.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.ElectricalThe advanced electronic systems of the Suzuki Intelligent Ride System (S.I.R.S.) let GSX-8S riders optimize performance characteristics to best suit their riding style, level of experience, and riding conditions. The GSX-8S instrument panel uses a full-color, 5-inch TFT LCD screen to give the rider information on these systems and their current settings.The four-mode STCS on the GSX-8S lets the rider control the throttle with more confidence by limiting rear wheel spin in a variety of riding conditions.
