Thirty-five years after the birth of the original GSX model, the GSX-S1000 takes the GSX line in an aggressive new direction. The product concept of GSX-S1000 is “Pure Sport Roadster.” The model is developed to provide maximum fun of sport riding on street. Both engine and chassis are developed to achieve an exciting riding experience. The basic performance aspects of “running,” “braking” and “cornering” are embodied to the fullest extent allowed with the latest state-of-the-art technology. The motorcycle is made for experienced, sport-minded enthusiasts who desire to enjoy sport riding on the street in an upright riding position.
The GSX-S1000 is powered by a four-stroke, liquid-cooled, DOHC, 999-cubic centimeter inline-four engine, street-tuned version of the legendary 2005-2008 GSX-R1000 engine, which was designed to provide smooth throttle response, immediate, controlled acceleration. In this GSX-S1000, the legendary engine is re-tuned for the real world riding environment, without detracting the power character of GSX-R1000 – the broad low-end torque and adrenaline rushing performance in the high rev range. It produces 107 kilowatts (143 horsepower) at 10,000 revolutions per minute and 106 Newton-meters at 9,500 rpm. New pistons were engineered with use of FEM (Finite Element Method) analysis to achieve optimal rigidity and weight. 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 spark plugs.
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) 44-millimeter throttle body (same size as GSX-R1000K7), the secondary throttle valves are controlled by servomotor for smooth power delivery and optimum combustion efficiency. Fuel injectors are 10-hole, long-nosed injectors on each throttle body to improve fuel atomization for better combustion efficiency while reducing fuel consumption. Meanwhile, the newly-designed, high-efficiency round-shaped radiator has strong cooling performance. The radiator shrouds efficiently guides air to radiator core. Liquid-cooled oil cooler is used unlike air-cooled type on the GSX-R1000.
The 2015 GSX-S1000 features Suzuki’s advanced traction control system to let the rider control throttle with more confidence in various riding conditions. As a result, the 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. It also confirms conditions every four milliseconds, and governs ignition, which allows extremely quick reaction. The rider can choose from three different modes, depending on personal preference or road conditions. Mode 1 has the lowest sensitivity level, allows certain level of rear wheel spin. It is suitable for sport riding in good road grip conditions. Mode 2 has the second lowest sensitivity level and activates slightly earlier than Mode 1. Mode 3 is the highest sensitivity level and the system activates earlier than other two modes. It is suitable in conditions with poor surface traction. Full LCD Instrument cluster is designed lightweight and compact. The LCD readouts include speedometer, tachometer, odometer, dual trip meter, gear position, water temperature, driving range, average fuel consumption, instant fuel consumption, traction control mode, fuel gauge and a clock.
GSX-S1000 features a new Suzuki Easy start system. On the regular motorcycle engine starting, the 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 those found in some recently introduced automobile. The 32-bit ECM recognizes the signals and keeps starter motor working for a certain time. Thanks to the new system, the rider doesn’t have to pull the clutch lever in engine starting. Seat height is 810 millimeters, the lowest in the 1000-cc sport naked class. Newly designed mainframe is aimed to provide nimble handling and great road holding performance. Newly equipped, 43-mm KYB Inverted front fork has 120-mm stroke and provides sporty yet plush ride. The front fork has fully adjustable damping, rebound, compression and spring pre-load. Link-type shock unit has 63-mm stroke, tuned for a superb handling. Anti-lock brake system (ABS) monitors wheel speed 50 times per wheel rotation, and matches stopping power to available traction. Dunlop radial tires, D214F (front) and D214R (rear) provide great grip in sport riding on the public roads. Handlebar is Renthal Fatbar and is made from aluminum. Its tapered design increases the rigidity of the handlebar and reduces weight and vibration.
The Suzuki GSX-S1000 is now available at Suzuki Big Bikes Center in Makati City with a price tag of P599,000.
