suzuki 2021 GSX S1000



Born of race-winning, track-proven DNA and raised for the street, the honed physique of the new GSX-S1000 morphs it into an even tighter and more striking package that is ready to turn heads and own the streets. It’s all about commanding performance, greater controllability, rider usability, and looks that can’t be beaten.


The high-performance 999cc four-stroke DOHC liquid-cooled inline-four engine that powers the GSX-S1000 inherits true winning superbike DNA. This street-tuned engine is based on core architecture that benefits from know-how acquired over decades of developing the GSX-R1000 to win countless production race victories, while also incorporating advanced technologies developed for MotoGP racing.


Every aspect of performance has been refined. Overall power output is increased and is stronger through the low- to mid-range engine speeds most commonly used. A broader, smoother torque curve featuring greater cumulative torque production consistently delivers abundant 

power throughout the engine’s operating range and particularly shines in the mid to high rpm range. Revised exhaust and intake cam profiles decrease the amount of lift and reduce valve lift overlap to achieve a better overall balance of performance and controllability across a broad range of engine speeds, while also contributing to improved emissions performance. Changes to the internal structure of the new air cleaner box help improve power output characteristics. A change to the bore size of the new electronic throttle bodies helps achieve a better balance between idling throttle response and power output characteristics.


A clean, sharp look and exciting sound, the 4-2-1 exhaust system is designed and tuned to maximise overall performance, help satisfy Euro 5 emission standards and enhance the quality of its exhaust note. The design includes a new layout behind the collector, a new chamber structure, and the addition of a second catalytic converter inside the chamber. The redesigned structure of the connecting pipes between cylinder pairs increase the performance of the secondary air injection system, which improves the ability to purify exhaust gases. In addition, the collector is now marginally longer and the Suzuki Exhaust Tuning (SET) system is positioned a little differently.


Adopting both slip and assist functionality.

The slipper clutch partially disengages to reduce negative engine torque and mitigate the effect of engine braking when downshifting from high rpm. This helps prevent the rear tyre from locking up or hopping and provides smoother deceleration, enabling the rider to shift down with greater confidence and maintain better control when downshifting into corners.

The assist function increases the clutch’s clamping force under acceleration and thereby allows the use of softer springs while still efficiently transferring torque to the rear wheel. This results in light clutch lever operation, which reduces left hand fatigue when stuck in traffic jams, or in other situations that require frequent clutch lever operation.

Engineered For Excitement

Just looking at the chassis design, you can sense how agile, controllable and fun the GSX-S1000 is to ride. Every aspect reflects engineering focused on delivering great handling
and control, whether riding on city streets, negotiating twisty mountain roads, or even taking the GSX-S1000 to the track.

Compact and Lightweight

The chassis features a compact, lightweight package that makes the GSX-S1000 agile and predictable for a high-performance, large-displacement street bike. Its twin-spar aluminium frame helps deliver sharp handling and great road holding ability, while its straight main tubes are ideal for achieving high rigidity and low weight. All this connects to a ruggedly braced aluminium swingarm that further contributes to the road gripping character that lets you ride with confidence.

Brembo Brakes                 

The GSX-S1000 has high specification radial-mount Brembo monobloc calipers. The calipers each have four opposed 32mm pistons acting on a 310mm floating-mount disc for strong stopping power.

Adjustable KYB Suspension

The 43mm KYB inverted front forks give a ride that is smooth yet sporty. They feature 120mm of stroke and fully adjustable damping, rebound, compression and spring preload settings. The link-type rear suspension with adjustable rebound damping and spring preload settings reacts efficiently to varying road surfaces to maintain an agile and stable feel while helping offer up to 130mm of rear wheel travel. The suspension settings are tested and tuned to best match the internal structure of the tyre and realise precise handling and improved steering into corners.

High Performance Wheels and Tyres

Cast aluminium wheels feature sporty good looks and a rigid lightweight structure, in a six spoke design. These are fitted to Dunlop’s new SPORTMAX Roadsport 2 radial tyres rear, these benefit from an updated internal structure custom engineered to perform optimally on the GSX-S1000, as well as an optimised tread pattern with a new compound that enhances positive grip in wet conditions, warms up faster, and wears better.

The combination of these wheels and new tyres works harmoniously with the front and rear suspension settings to help realise the great grip, stability and quick handling demanded for sporty performance.

New 19L Fuel Tank

The new fuel tank increases capacity to 19L, without appearing larger. This benefits the rider by reducing the frequency of refuelling stops, giving a range of 194 miles possible based on the official WMTC fuel consumption of 46.31MPG.

The new GSX-S1000 adopts a collection of the advanced electronic systems that comprise the Suzuki Intelligent Ride System (SIRS). These enable the rider to optimise performance characteristics to best suit riding conditions and varying road surfaces, as well as their level of confidence and experience. These benefit the rider by instilling greater confidence and allowing them to concentrate on enjoying the riding experience.                     


This feature lets you shift up or down more quickly and easily without the need to operate the clutch or throttle. When activated, Quick Shift automatically interrupts power delivery just long enough to produce smoother, almost uninterrupted acceleration when you shift up. When decelerating, the system automatically opens the throttle valves just enough to increase rpm and match engine speed to the next-lower gear ratio. The result of this hands-free automatic blipping function combines seamlessly with engine braking to create a highly satisfying experience when downshifting. Bi-directional Quick Shift works in unison with SDMS to bring you even greater riding fun with a more linear feel.


STCS² is programmed to continuously monitor front and rear wheel speed, engine RPM, throttle position and gear position, and designed to limit power to prevent slipping when it determines an imminent loss of traction. This enhances stability to give you more confident control with less stress and fatigue. Now featuring a wider selection of five mode settings, this updated version of STCS² better fits a more diverse variety of riding conditions, styles, and level of experience. The system can be also turned off when preferred. The higher number the mode, the faster control kicks in and the more proactive the system is in limiting wheel spin.


Choose between three different power output modes. All three ultimately deliver maximum engine output, but offer control over the level of throttle response and torque characteristics when accelerating. This empowers you to maximise the GSX-S1000’s capabilities as a powerful street bike but enhances the overall riding experience by building in the flexibility to prioritise sports or stability characteristics to better match your intended riding style or adapt to changing weather, road and other conditions.
