Suzuki Intelligent Ride System(S.I.R.S.) Features
– The advanced electronic systems of the Suzuki Intelligent Ride System (S.I.R.S.) featured on the GSX-8S assist and help you optimize performance characteristics to match your changing riding needs and preferences. By making the GSX-8S feel more controllable, predictable, and less tiring to operate, these systems help you ride with greater peace of mind.
– Suzuki Drive Mode Selector (SDMS) lets you freely choose among three different power output characteristic modes to best match varying riding conditions or your preferences. While all three ultimately deliver maximum engine output, finer control over response and torque characteristics as you open the throttle to accelerate empowers you to ride with greater confidence and pleasure.
– Mode A (Active)
– Delivers the sharpest throttle response as you open the throttle. Torque characteristics are finely tuned to deliver exciting acceleration as the throttle is opened.
– Mode B (Basic)
– Features softer throttle response and a more linear power delivery curve as you open the throttle. Settings are tuned to help make the bike more controllable and a good fit for everyday riding.
– Mode C (Comfort)
– Offers yet softer throttle response and more gentle torque characteristics. This mode is useful when riding on wet or slippery surfaces.
– The Suzuki Traction Control System (STCS)* is designed to help prevent rear wheel slip, thereby reducing stress and fatigue while instilling greater confidence in controlling your ride. You can select from 3 modes to control how quickly the system takes effect and how proactive it is in limiting wheel spin, or you can opt to run with it turned off.
– Suzuki’s Ride-by-wire Electronic Throttle System realizes linear feedback to throttle grip action that responds faithfully to your every intention and makes the GSX-8S feel more controllable.
– The Bi-directional Quick Shift System lets you shift up or down while in motion without operating the clutch lever. When activated, this standard-equipment system delivers clean upshifts with smooth acceleration, as well as quick and easy downshifts. The gear shift linkage system load rate is optimized to provide a solid, satisfying click with each shift that assures you the gearbox has responded immediately to your action.
– By helping prevent engine speed from dropping excessively when you pull away from a standing start or ride at low speeds, Low RPM Assist delivers smoother starts and inspires greater confidence when you are riding in stop-and-go traffic, or doing U-turns.
– Suzuki Easy Start System lets you start the engine with just one quick press of a button. As a function used on every outing, it makes your riding experience all the more pleasurable and convenient.
* 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.
