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

  • The advanced electronic systems of the Suzuki Intelligent Ride System (S.I.R.S.) help GSX-8R riders optimize performance characteristics to best suit their riding style, their level of experience, and riding conditions. This helps make the GSX-8R sportbike more predictable, and enjoyable on a spirited ride or commuting, and it always helps add up to a more exciting, confident, and fun riding experience.
  • SUZUKI TRACTION CONTROL SYSTEM (STCS)*: The four-mode STCS on the GSX-8R lets the rider control the throttle with more confidence by limiting rear wheel spin in a variety of riding conditions. STCS continuously monitors front and rear wheel speeds, throttle opening, engine speed, and transmission gear. It quickly reduces engine output when it detects wheel spin by adjusting ignition timing and air delivery. The rider can select one of four modes (1, 2, 3, and OFF). The three active modes differ in terms of rear wheel spin sensitivity. Mode 1 is the lowest sensitivity – it allows a certain degree of rear wheel spin and is best suited for good road conditions. Mode 2 is a moderate sensitivity level – the system engages traction control sooner than Mode 1 and is for average road conditions. Mode 3 is the highest sensitivity level – the system engages traction control sooner than the other modes helping to virtually eliminate wheel spin, and is well-suited for poor or slippery road conditions, like wet and cold surfaces. OFF disengages all traction control features – the rider has sole control of the engine’s throttle and any resulting rear wheel spin. The STCS modes are displayed on the TFT instrument panel and can be changed on-the-fly, using the left handlebar switch. When the system is trimming power to prevent wheel spin, the TC icon on the instrument panel will illuminate and flash. (* 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.)
  • The GSX-8R’s S.I.R.S. suite includes the Suzuki Drive Mode Selector (SDMS), the Suzuki Traction Control System* (STCS) (* 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.) and the Bi-directional Quick Shift System (QS). The S.I.R.S. suite of rider aids also includes the Ride-by-Wire Electronic Throttle System, the Suzuki Easy Start, and Low RPM Assist systems for accurate and convenient motorcycle operation.
  • RIDE-BY-WIRE ELECTRONIC THROTTLE SYSTEM: The electronic throttle system uses the capability of the GSX-8R’s 32-bit, dual-processor ECM, and CAN-bus wire harness to convert throttle grip movement and sensor input into instantaneous and precise throttle plate movement in the two 42mm throttle bodies. This system also tunes throttle body action to best match each of the S-DMS modes. The result is a controllable, linear power delivery that responds faithfully to the rider’s intentions, whether commuting or enjoying a sporty ride on a winding road.
  • SUZUKI DRIVE MODE SELECTOR (S-DMS): S-DMS provides the rider with a choice of three different engine power output modes. Working in concert with the Traction Control System*(* 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.), S-DMS permits peak power in each mode while changing the nature of the power delivery. These three modes (A, B, and C) provide the rider with a quick and effortless way to alter the GSX-8R’s power delivery characteristics to match his or her riding style or adjust to changing weather, road surface, or other conditions. Mode A (Active) is for active, sporty use that delivers the sharpest throttle response as the rider opens the throttle. Mode A’s torque characteristics are finely tuned to deliver exciting acceleration when hitting the throttle hard, such as when participating in track day events or enjoying a sporty run on clean, winding roads in clear weather. Mode B (Basic) is for general, all-around riding, as it features softer throttle response and a more linear power delivery curve as the rider opens the throttle. Settings are tuned to fit a wide range of riding styles and conditions and to help control engine power in everyday riding situations. Mode C (Comfort) offers a softer throttle response and more gentle torque characteristics, with power increasing in a directly linear fashion as the throttle is opened. This mode is useful when riding on wet or slippery surfaces, or when the rider desires a relaxing, comfortable ride. Using the mode and select switches on the left handlebar, the rider can change S-DMS modes while riding. The mode settings are clearly displayed on the color TFT instrument panel.
  • BI-DIRECTIONAL QUICK SHIFT SYSTEM (QS): This QS system allows the GSX-8R rider to shift up or down quickly and easily, without operating the clutch or throttle. To ensure smoother upshifts, QS automatically interrupts power delivery just long enough to produce smooth, almost uninterrupted acceleration. When decelerating, the system automatically opens the throttle valves just enough to increase RPM and match engine speed to the next lower gear. The result is that this hands-free, automatic function combines seamlessly with engine braking to create a highly satisfying experience when downshifting. The bi-directional QS works seamlessly in concert with S-DMS to bring riders even greater riding enjoyment. Performance of the GSX-8R’s SACS-style, assist-and-slipper clutch ensures even smoother up - and down-shifts when using QS or manual clutch operation. An icon on the TFT instrument panel (between the speedometer and gear position display) indicates QS status. The QS system can be easily switched on or off using the left-handlebar switch. The shift 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.
  • THE LOW RPM ASSIST SYSTEM: The Low RPM Assist system seamlessly increases engine speed to smooth the power delivery when launching from a standing start or when riding at low speeds, helping ensure better control and operation in stop-and-go traffic. The system also minimizes the possibility of the rider stalling the motorcycle during take-off.
  • THE SUZUKI EASY START SYSTEM: Easy Start allows the rider to easily start the engine with a single, momentary press of the starter button. At any air or engine temperature, there is no need to hold down the starter button until the engine fires. The ECM manages Easy Start so the starter motor automatically stops once the engine has started.
  • S.I.R.S. SUPPORTING TECHNOLOGIES: Controller Area Network (CAN bus). Key to the operation of the S.I.R.S., the GSX-8R uses an interconnected information network instead of a conventional wiring harness. Because it requires fewer wires, this CAN bus wiring lets the GSX-8R be lighter and simpler and provides a way for the advanced components – such as the quick shifter – to have faster data transmission with the ECM. The CAN bus also provides a single connection point for diagnosing any errors that may occur throughout the entire network.
  • ENGINE CONTROL MODULE (ECM): The 32-bit, dual-core ECM has a fast processor and specialized programming to efficiently operate the fuel-injection system, Ride-by-Wire throttle bodies, ignition, and other electrical features on the GSX-8R.

Transmission Features

  • 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, enabling the rider 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.
  • The SCAS also works as an assist clutch, increasing plate pressure under acceleration, but always helping keep the clutch lever’s pull light and precise.
  • 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.

Additional Features

  • 12-month, unlimited mileage limited warranty. Longer coverage periods with other benefits are available through Suzuki Extended Protection (SEP).
  • A variety of Suzuki Genuine Accessories are available for the GSX-8R, such as a solo seat cowl, billet clutch and brake levers, fuel tank, and engine cover protectors, clip-on tank bags, plus a selection of Suzuki logo apparel.
