2021 SUZUKI GSX-S1000 ENGINE FEATURES
The Suzuki GSX-S1000’s long-stroke GSX-R engine has been refined to produce a broad, smooth torque curve through the full rev-range with increased peak horsepower.
The Suzuki GSX-S1000 provides predictable and controllable throttle response with abundant top-end power to provide the rider an exciting riding experience.
New camshaft profiles decrease lift and valve overlap not only to improve emissions, but balance the engine’s performance and drivability, enhancing rider control.
New valve springs are calibrated to the new camshafts to aid performance and improve durability.
The cam chain tensioner and tension adjuster are updated to reduce friction and improve durability.
Suzuki’s legendary Twin Swirl Combustion Chamber (TSCC) design is machined into the cylinder head that, with the flat-top pistons, achieves an optimal 12.2:1 compression ratio that helps deliver a broad spread of power throughout the entire rev range.
Aluminum pistons, engineered with use of Finite Element Method (FEM) analysis, are cast with optimal rigidity and weight.
Ventilation holes between the cylinders reduce pumping loss within the crankcase so the engine can deliver more power and torque.
Suzuki Composite Electrochemical Material (SCEM)–plated cylinders integrated into the upper crankcase reduce friction and improve heat transfer and durability.
The engine finish is revised to present an even stronger image of quality while the design of the engine covers (clutch, stator, and drive sprocket) are updated with a new shape and finish.
New electronic throttle bodies are used on the Suzuki GSX-S1000, so engine response is smooth and controlled, especially when the rider is applying the throttle to accelerate out of a corner.
These new Ride-by-Wire throttle bodies provide precise control for the Suzuki Drive Mode Selector (SDMS), Traction Control (TC), and Bi-directional Quick Shift system (QS).
Long-tip, 10-hole fuel injectors on each throttle body improve fuel atomization, while the automatic Idle Speed Control (ISC) improves cold starting and stabilizes the engine idle.
The air cleaner has a new internal structure that contributes to the Suzuki GSX-S1000’s increased engine performance while maintaining the exciting intake sound that the Suzuki GSX-S1000 is renowned for.
The air cleaner’s external shape is changed to accommodate the larger capacity fuel tank.
Retaining the under-chassis design, sharp looks and exciting note of the prior generation’s system, the Suzuki GSX-S1000’s new stainless steel, 4-2-1 exhaust system is completely redesigned and tuned.
Behind the header pipes, the redesigned mid-chamber contains a second catalytic converter to help ensure emissions compliance, a low center-of-gravity, and good exhaust flow to help the engine deliver a strong low- to mid-range punch with an exciting rush to redline.
A refined Suzuki Exhaust Tuning (SET) valve manages flow from the mid-chamber into the sculpted muffler that has a pleasing appearance that’s not common to under-chassis exhausts while creating an exciting, distinctive sound.
With the catalytic converters located in the mid-chamber, Suzuki GSX-S1000 riders can fit an EPA or CARB-compliant silencer from suppliers such as Yoshimura R & D, USA.
The digital ignition fires iridium-type spark plugs that increase spark strength and combustion efficiency, contributing to higher power, more linear throttle response, easier engine start-up, and a more stable idle. These quality components also last longer than conventional spark plugs.
The restyled radiator shrouds efficiently guide cooling air to the high-capacity curved radiator.
A thermostatically controlled cooling fan helps ensure lower coolant temperatures when riding in slow moving traffic. The design also defects hot air away form the rider at speed.
Additional heat is removed from the engine via the use of a lightweight and compact liquid-cooled oil cooler (like those used on certain Suzuki GSX-R models).
TRANSMISSION FEATURES
Like a Suzuki GSX-R1000, the race-proven, six-speed, close-ratio transmission features vertically staggered shafts to reduce overall engine length.
The precise shift linkage helps the rider easily and quickly select the best gear for the riding conditions.
A new rotary sensor sends shifter movement data to the ECM, so the Bi-directional Quick Shift system precisely responds to the rider’s actions. This new design eliminates situations where previous designs incorporated into the shift rod could cause a vague feeling at the shift lever or could be easily damaged in a tip-over.
The gearshift cam, shift shaft and clutch release cam were also revised to support the function of the new, bi-directional Quick Shift system.
The latest version of the Suzuki Clutch Assist System (SCAS) clutch is fitted to the Suzuki GSX-S1000. More than ever before, the SCAS clutch increases plate pressure under acceleration, yet acts as a slipper clutch to smooth the engine response during engine braking and corner entry.
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.

SUZUKI INTELLIGENT RIDE SYSTEM (S.I.R.S.) FEATURES
The Suzuki Drive Mode Selector (SDMS) provides the rider a choice of three different engine power output modes. All three modes deliver maximum engine output but provide different throttle response and torque characteristics when accelerating.
These three modes (A, B, and C) provide the rider a quick and easy way to alter the GSX-S1000’s power delivery characteristic to match his or her riding style, or adjust to changing weather, road and 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 good 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 make the bike more controllable 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 SDMS modes while riding. The mode settings are clearly displayed on the LCD instrument panel.
The advanced Ride-by-Wire Electronic Throttle System leverages the capability of the 2021 Suzuki GSX-S1000 32-bit ECM and CAN-style wire harness to precisely control engine output relative to throttle action.
This precision allows the throttle body action to be tuned to best match each of the SDMS 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.
The five-mode Suzuki Traction Control System (STCS) continuously monitors front- and rear- wheel speed, engine RPM, throttle position and gear position to adjust engine output to prevent undesired rear wheel spin, helping maintain traction and power delivery to the road.
Compared to the three-mode system on the prior generation GSX-S1000, this updated, five-mode version of STCS features a wider selection of sensitivity to better accommodate a variety of riding conditions, styles, and rider experience. The system can also be turned off when preferred. The higher number the mode, the quicker STCS intervenes to limit rear wheel spin.
The STCS modes are displayed on the LCD 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 in the center of the instrument panel will illuminate and flash.
The Bi-directional Quick Shift System (QS) allows the rider to shift up or down quickly and easily, without operating the clutch or throttle.
To ensure smooth 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 of this hands-free, automatic blipping function combines seamlessly with engine braking to create a highly satisfying experience when downshifting.
The bi-directional QS works seamlessly in concert with SDMS to bring riders even greater riding enjoyment.
Performance of the GSX-S1000’s new SACS-style assist & slipper clutch ensures even smoother up- and down-shifts when using QS or manual clutch operation.
A new style rotary sensor sends shifter movement data to the ECM, so the Bi-directional Quick Shift system precisely responds to the rider’s actions.
The Suzuki Easy Start System lets the rider start the motorcycle with a simple press of the starter button. There is no need to pull in the clutch lever when the transmission is in neutral, and the starter motor automatically disengages, the instant the engine fires up.
The Low RPM Assist System seamlessly increases engine speed to smooth the power delivery when launching from a standing start or riding at low speeds, which helps 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.
