Just unveiled is the new Suzuki GSX-S1000 ABS. A street bike with the heart of a race machine, this is basically a ready-made GSX-R1000 street fighter.
Traction control and ABS help to tame this supersport motor, while a less aggressive riding position should make this a fun, but – dare we say it – almost practical bike.
35 years after the birth of the original GSX model, the GSX-S1000 takes the GSX line in an aggressive new direction. The roots of the GSX series started in 1976 with the GS750 – Suzuki’s first four-stroke in-line-four cylinder sports bike. In 1980, the GS engine evolved to a 16-valve design with the introduction of the GSX750E. It was the origin of the glorious GSX lineage, followed by the radical GSX1100S KATANA in 1981, and the legendary, original GSX-R750 in 1985.
The concept of the original GSX was high-performance sportsbike which has broad power band, nimble handling, and great durability. Its heritage is still alive in the engineering philosophy of the all current GSX models, from top-end Moto GP race machine to street legal on-road bikes.
Here are the full details of this new bike, straight from Suzuki:
Engine design – outline
Four-stroke, liquid-cooled, DOHC, 999cm3 inline-four engine, street-tuned version of the legendary 2005-2008 GSX-R1000 engine, is designed to provide smooth throttle response, immediate, controlled acceleration. That results in exciting, adrenaline-rushing performance in sport riding.
- We chose 2005-2008 GSX-R engine, not using that of the current GSX-R1000. The reasons are;
- Because of its long stroke design, it has broad low-to-mid range power/torque that is more suitable for street riding.
- Because of its crankshaft/gearbox layouts, the main frame can be designed straight from steering head to swing-arm pivot. It enables us to design the main frame lightweight.
- 2005-2008 generation GSX-R1000 won number of championship all over the world. This engine has great reputation in the market.
The GSX-R1000 engine, which started out as a long-stroke version of the GSX-R750 engine, has a long-stroke design with a 73.4mm bore and 59.0mm stroke. The long-stroke design allows the combustion chamber to be compact. It makes it possible to regulate compression ratio while maintaining a flat-top piston shape and power characteristics with a broad spread of power throughout the rev range can be obtained.
In this GSX-S1000, the legendary engine is re-tuned for the real world riding environment, without detracting the raw power of GSX-R1000 – the broad low-end torque and adrenaline rushing performance in the high rev range.
|Bore x Stroke||73.4mm x 59.0mm|
|Compression ratio||12.2 : 1|
Pistons and Piston Rings
- New pistons were engineered with use of FEM (Finite Element Method) analysis to achieve optimal rigidity and weight.
- The piston and piston rings are designed 3% lighter than that of the 2007 GSX-R engine without compromising the durability.
- The new cam profiles are designed to optimize the valve timing to tune the GSX-R1000 engine – which is designed keeping in mind racetrack use – to obtain the GSX-S1000 power character that’s more suited to the streets and winding roads.
- Iridium spark plugs heighten the spark strength and combustion efficiency, thereby contributing to higher power, more linear throttle response, easier engine start-up, and a more stable idle compared to conventional type.
- Suzuki Composite Electrochemical Material (SCEM)-plated cylinders integrated into the upper crankcase reduce friction and improve heat transfer and durability.
- Fuel injection system employs Suzuki’s original, SDTV (Suzuki Dual Throttle Valve) 44mm throttle body (same size as GSX-R1000K7), the secondary throttle valves are controlled by servo motor for smooth power delivery and optimum combustion efficiency.
- Fuel injectors are 10-hole; long-nosed injectors on each throttle body improve fuel atomization for better combustion efficiency and while reducing fuel consumption.
- Fuel injection works with O2 feedback system and intake pressure sensor for optimum combustion efficiency in various conditions, reduces emissions to meet Euro 3 requirement.
- Air cleaner is newly designed to match with required intake capacity.
- The air cleaner has partition plate inside the box, which guides air into the box, that increases intake efficiency and reduces intake noise.
- Exhaust system is newly designed to achieve clean looks, exciting exhaust notes, and adrenaline-rushing performance.
- The exhaust system is 4-into-2into-1 system, it has equalizer pipes between 1 and 4, 2 and 3 header pipes. This design contributes to stronger low-to-mid range output by fine tuning the exhaust pressure waves.
- The system has exhaust chamber after the joint section. The chamber is carefully shaped to fit under the engine. Thanks to the exhaust chamber, the muffler size is minimized for clean, agile look of rear section.
- The exhaust system contains catalyzer for clean emission. It conforms to the strict Euro 3 emission regulations.
- The new GSX-S1000 uses the Suzuki Exhaust Tuning (SET) system. A butterfly valve is actuated by a servo motor. The amount of valve opening is determined by engine rpm, throttle position and gear position. The SET system controls exhaust pressure waves in order to improve engine combustion at low rpm.
Radiator Newly designed, High-efficiency round shaped radiator has strong cooling performance. The radiator shrouds efficiently guides air to radiator core.
Oil Cooler Liquid-cooled oil cooler is used unlike air-cooled type on the GSX-R1000. Benefit of liquid-cooled oil cooler is lightweight, compact and clean look. Thanks to its compact design, it creates room for exhaust pipes.
Three-Mode Traction Control System
2015 GSX-S1000 features Suzuki’s advanced traction control system to let the rider to control throttle with more confidence in various riding conditions. As a results rider can enjoy sport riding with more confidence, with less stress and fatigue.
Suzuki’s traction control system continuously monitors front and rear wheel speeds, throttle position sensor, crank position sensor and gear position sensor, and quickly reduce engine output when wheel spin is detected. Engine output is controlled by managing ignition timing and air delivery to ensure smoother traction control operation.
Suzuki’s Traction control system confirms conditions every 4 milliseconds, and governs ignition, which allows extremely quick reaction.
Suzuki’s system precisely controls output by optimizing ignition timing and air delivery depends on the conditions. That results in smooth, natural control of power, which does not bother sport riding even in the system is working.
Rider can select 3 different modes 1, 2, 3 and off, depends on conditions or rider’s preference. The difference between mode 1, 2 and 3 is sensitivity levels.
Mode 1 is the lowest sensitivity level, allows certain level of rear wheel spin. It is suitable for sport riding in good grip road conditions.
Mode 2 is the second lowest sensitivity level. System activates slightly earlier than Mode 1. It is suitable for most of the riders and road conditions.
Mode 3 is the highest sensitivity level, system activate earlier than other 2 modes. It is suitable in bad road conditions.
|Mode||Sensitivity level||Suitable conditions|
|1||Low||Sport riding, good road conditions|
|2||Middle||City riding, regular road conditions|
|3||High||Wet or cold conditions|

Bar-type tachometer features “peak-hold” function, which shows peak rpm when rpm drops. So rider can recognize the peak rpm of the last moment when downshifting.
Suzuki Easy Start System
GSX-S1000 features a new Suzuki Easy start system. On the regular motorcycle engine starting, rider need to press-hold the starter switch until the engine fires up. On the GSX-S1000, all you need to do is just one-push the starter switch just like the recent automobile’s engine start system. The 32-bit ECM recognizes the signals and keeps starter motor working for a certain time.
Thanks to the new system, rider doesn’t have to pull the clutch lever in engine starting (when the gear is in neutral).
