Seen at Intermot, the 2015 Suzuki GSX-S1000 is now available in Singapore. Tuned for street use, the roadster has a similar inline-four engine found in the previous GSX-R1000 racing machines.
What’s different from the track racing machines is an all-new aluminum frame chassis exclusively designed for the GSX-S1000, as well as a three-way selectable traction control system and ABS equipped braking system, something very much welcomed on our wet-weather riding conditions.
For road riding it’s definitely a brilliantly thought-out bike, beautifully designed and sculptured by the Suzuki design team. To prove that it’s all go and not just show, the GSX-S1000 has adjustable preload and rebound forks and rear suspension. Radially mounted Brembo monoblock calipers make the closing statements that this is definitely not a budget road-based play bike.
More information about the engine
The GSX-S1000 is powered by a street-tuned version of the four-stroke, liquid-cooled, DOHC, 999cm3 , inline-four engine that became a legend in the 2005-2008 GSX-R1000. The newly honed engine delivers smooth throttle response and immediate, controlled acceleration, so the sport rider experiences adrenaline-rushing performance.
A long-stroke design with a 73.4mm bore and a 59.0mm stroke allows the combustion chambers to be compact. It therefore allows a combination of an optimal compression ratio, a flat-top piston shape, and a broad spread of power throughout the rev range.
Advances inside the engine begin with the pistons. Suzuki used finite-element-analysis techniques to make the pistons light without compromising their rigidity. The benefits include broad torque and quick acceleration.
New cam profiles optimize the valve timing to achieve power characteristics that are ideally suited to city streets and twisty suburban roads. Iridium spark plugs ensure strong sparks for efficient combustion that translates into higher power, linear throttle response, easier engine startup, and stable idling.
Each bore is plated with Suzuki’s own race-proven nickel-phosphorus-silicon-carbide coating, which reduces friction, enhances heat transfer, durability, and ring seal, and is known as Suzuki Composite Electrochemical Material (SCEM).
A newly designed radiator with an efficient round shape helps to keep the engine temperature consistent. Shrouds guide air to the radiator core. A liquid-cooled oil cooler is light and compact. Its small dimensions help to make the bike look neat by creating more room for the exhaust system.
The Traction controls…
Suzuki’s advanced traction control system lets the rider control the throttle with more confidence in diverse conditions, so it makes sport riding more enjoyable and less tiring. The system checks the front and rear wheel speeds, the throttle position sensor, the crank position sensor, and the gear position sensor 250 times a second. It quickly reduces engine output by effecting control over the ignition timing whenever it detects wheelspin.
The system’s control over engine output feels so smooth and natural, it does not detract from riding pleasure. The rider can set the system to any of three modes or turn it off. The modes differ in terms of sensitivity. Mode one is for sport riding with minimal intervention from the system. Mode three gives maximal traction control for riding in poor conditions. Mode two offers a balance that is ideal for typical road conditions.
Do note that the traction control system is not a substitute for the rider’s throttle control under any conditions. It cannot prevent loss of traction due to excessive speed when the rider is entering a turn and or braking. Also, it cannot prevent the front wheel from losing grip.
Chassis and suspension duties…
Suzuki designed a new chassis in a compact, lightweight package that makes the GSX-S1000 agile and fun to ride. Every aspect of the chassis reflects a focus on great handling and control in real-world conditions from city streets to twisty mountain roads.
The main frame helps to ensure nimble handling and great roadholding. The main tubes are straight from the steering head to the swingarm pivot. Their shape is ideal for achieving high rigidity and low weight. Suzuki used finite-element-analysis techniques to make the frame even lighter than that of the current GSX-R1000. The sturdy aluminum-alloy swingarm comes straight from the current GSX-R1000. It is ruggedly braced and helps to ensure great roadholding together with superbike looks.
Suzuki optimized the riding position for greater comfort and slimmed down the knee-grip area for relaxing ergonomics. The slim bodywork combines with the low seat (815mm from the ground) to help the rider put his feet down easily.
Newly specified 43mm KYB inverted front forks give a ride that is sporty yet plush. They have fully adjustable damping, rebound, compression and spring preload. The cast-aluminum wheels have a brand-new lightweight, six-spoke design that gives a combination of nimble handling and sporty looks. Dunlop radial tyres (120/70ZR17 at the front; 190/50ZR17 at the rear) provide great grip for sport riding.
