2025 Suzuki GSX-8S

Designed 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:

Engine
  • The 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.
Transmission
  • 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 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.
Chassis
  • Designed 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.
Electrical
  • The 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.
