It is a revolutionary motorcycle that changed production- based racing forever. Filling racing paddocks around the globe, and driving would-be competitors from the grid. A machine so dominant that other brands abandoned the 750cc racing class because they could not compete.
The GSX-R slogan, Own The Racetrack, is based solidly in fact. Say GSX-R75O, and the world thinks of a racebike with lights, with the best possible balance of engine and chassis performance.
For 2007, the latest version of the legendary GSX-R7SO continues to relentlessly advance high-performance technology. Combining the responsive torque and broad, smooth powerband of a heavyweight with the compact size and easier handling of a middleweight. Now more compact . More powerful. More aerodynamic.
Engine FeaturesCompact & lightweight 4-stroke, 4-cylinder, liquid-cooled engine designed for overall weight reduction, optimum combustion efficiency and power deliveryCylinder head with narrow valve angles creating a compact combustion chamber design, 12.5:1 compression ratio, large intake and exhaust ports for optimum intake and exhaust efficiency and high power outputLightweight titanium valves with steel alloy springs and aluminum spring retainers operated by thin-wall hollow camshafts to reduce weight and inertiaLightweight forged aluminum alloy pistons with short skirts, cut away sides and an anti-friction surface finish along with shotpeened chrome-moly steel connecting rods for improved strenthOne-piece cylinder block and upper crankcase section is equipped with 39mm ventilation holes between cylinders to reduce crankcase pressure and mechanical lossTapered, 50mm double-barrel throttle body design features Suzukis SDTV throttle valve system, plus twin multi-hole-type injectors per cylinder for optimum performance and throttle responseCrankshaft features forged steel construction and a secondary balancer shaft for reduced vibration at high rpm.Crankshaft and transmission shafts are positioned to create a compact engine design and the engine itself is rotated slightly forward in the chassis allowing for straighter and shorter intake and exhaust portsNew back torque limiting clutch allows smoother downshifts and works in conjuction with an updated six speed transmission with revised internal gear ratios and updated shift forksInnovative new Suzuki Advanced Exhaust System (SAES) with new under engine muffler layout and Suzuki Exhaust Tuning (SET) system for maximum mass centralization, superior aerodynamics, and improved low-to-mid range performanceHigh capacity large trapezoidal-shaped radiator provide efficient engine cooling - includes compact cooling fan assembly designed for improved air flowSuzuki Idle Speed Control (ISC) system improves cold starting and stabilizes engine idle speed in a variety of conditions.SRAD ( Suzuki Ram Air Direct) force feeds cool, pressurized air into the airbox at highway speeds, improving engine effeciency and throttle response
